Take a look around your home.

0:00:040:00:05

Can you be sure that every appliance is safe?

0:00:080:00:10

Is everything a company tells you about a product true?

0:00:130:00:16

And are you getting the best value for your money?

0:00:170:00:20

With the help of the country's top experts, we're going to see

0:00:220:00:25

what it takes to test the household products we use every day.

0:00:250:00:29

We'll discover how they're pushed to their limits.

0:00:320:00:35

We'll put the makers' claims on trial...

0:00:370:00:39

..and show you how to make your money go further.

0:00:410:00:45

You'll find these products in any ordinary house

0:00:450:00:48

but this is no ordinary house and no ordinary street.

0:00:480:00:53

This is the Watchdog Test House.

0:00:530:00:55

Hello.

0:01:010:01:03

We're deep inside one of Britain's leading science centres.

0:01:030:01:06

Here at the Building Research Establishment,

0:01:060:01:09

some of the products and materials that we use every day

0:01:090:01:12

are put to the test to make sure that they're safe,

0:01:120:01:16

environmentally friendly and that they don't fall apart.

0:01:160:01:20

Coming up on today's programme...

0:01:200:01:22

Beware of what you eat from abroad.

0:01:220:01:25

I ran to the bathroom

0:01:250:01:27

and I spent probably the next 36 hours either in bed

0:01:270:01:33

or the bathroom, literally thinking I was going to die.

0:01:330:01:36

We're out with the Port Health Authority,

0:01:360:01:38

the front line for the safety of food products coming into the UK.

0:01:380:01:42

When we're talking about the size of containers

0:01:420:01:46

and the potential problems for illness,

0:01:460:01:49

it really is quite enormous.

0:01:490:01:51

HDMI cables - they connect your TV to your DVD player

0:01:510:01:55

but are you paying over the odds?

0:01:550:01:58

It would be a guess between the two, so I'm going to plump for the left.

0:01:580:02:02

And the development of the baby buggy.

0:02:020:02:05

Imagine that this carrot is a child's finger.

0:02:050:02:09

As the frame collapses,

0:02:090:02:10

you might pull on the handle to stop that happening.

0:02:100:02:14

It's not been an easy ride

0:02:150:02:17

but are we any closer to ensuring all children are safe?

0:02:170:02:20

Now, from tea bags to takeaways, we come into contact

0:02:250:02:30

with ingredients from other countries every day,

0:02:300:02:33

all of which must comply with our hygiene and safety rules.

0:02:330:02:36

But with billions of pounds worth of imported food coming in every month,

0:02:360:02:41

testing everything is impossible

0:02:410:02:43

and harmful products can get through.

0:02:430:02:45

This was the Street Spice Festival in Newcastle,

0:02:470:02:50

held between 28th February and 2nd March in 2013.

0:02:500:02:55

An estimated 12,000 people from across the region attended

0:02:550:02:58

the event, including young mum Jennifer Jennings.

0:02:580:03:01

It was really busy. People seemed really excited.

0:03:030:03:05

You had to queue quite a bit to buy anything,

0:03:050:03:07

so we walked around a couple of times and then sort

0:03:070:03:10

of the atmosphere, people were just really happy

0:03:100:03:13

and having a good few drinks.

0:03:130:03:14

But what started as a good day out turned into a nightmare.

0:03:140:03:18

We went for the savoury pancake.

0:03:180:03:20

The next day, I turned to my mum and said that I wasn't feeling too well,

0:03:200:03:24

and then I ran to the bathroom

0:03:240:03:26

and I spent probably the next 36 hours either in bed

0:03:260:03:32

or the bathroom, literally thinking I was going to die. It was

0:03:320:03:37

horrific. I've never felt pain like it, apart from when I was in labour.

0:03:370:03:41

29 people at the Spice Festival were later diagnosed with

0:03:410:03:44

Salmonella poisoning,

0:03:440:03:46

25 of whom had a strain never before seen in humans in the UK.

0:03:460:03:50

Further analysis suggested that other organisms, including

0:03:500:03:54

E. coli and Shigella, may have also been present.

0:03:540:03:57

I found out from a letter from Environmental Health saying that

0:03:570:04:01

it was Salmonella that they'd found, to do with the curry leaves

0:04:010:04:07

that were within the chutney on the side of the pancakes.

0:04:070:04:10

When, obviously, disclosed that it was faecal germs,

0:04:100:04:14

I wasn't too impressed.

0:04:140:04:16

This was one of the largest outbreaks of gastro-intestinal

0:04:160:04:20

illness associated with herbs or spices in the UK.

0:04:200:04:24

But the bigger concern was whether there was enough understanding

0:04:240:04:27

amongst food handlers in general about the potential

0:04:270:04:31

for infection when using these products raw.

0:04:310:04:33

On this occasion, no action was taken.

0:04:330:04:37

It really bothers me that the leaves, obviously, were imported,

0:04:370:04:41

and that it wasn't checked. With having a four-year-old, she's...

0:04:410:04:46

If she'd been with me, she would have eaten exactly the same

0:04:460:04:49

things and it could have been a lot worse for her.

0:04:490:04:53

Imported food - that's any food coming into this country

0:04:530:04:55

from outside the European Union - is governed by the

0:04:550:04:59

European Food Safety Regulations, and it's the local authorities

0:04:590:05:03

and the Port Health authorities that are responsible for policing them.

0:05:030:05:07

Regular checks on food at the point of import are in place across

0:05:070:05:11

the UK and food that doesn't comply may be seized, tested and destroyed.

0:05:110:05:16

We're the front line for food safety of products

0:05:160:05:20

coming into the UK and the European Union.

0:05:200:05:23

When we're talking about the size of containers

0:05:230:05:27

and the potential problems for illness,

0:05:270:05:30

it really is quite enormous.

0:05:300:05:32

Sandra and her team carry out daily checks on consignments that

0:05:320:05:36

arrive into one of the UK's biggest ports, Southampton.

0:05:360:05:39

In the past, we've stopped anything from noodles containing

0:05:390:05:44

aluminium, cooked prawns containing Salmonella, nuts,

0:05:440:05:49

dried fruit containing aflatoxins and sometimes illegal products from

0:05:490:05:54

countries that are not permitted to export to the European Union.

0:05:540:05:58

There is a whole range of products now today that arrived

0:05:580:06:01

either this morning or yesterday, and they will be inspected

0:06:010:06:05

and sampled before they go into the country.

0:06:050:06:09

Inspections take place in clean environments to make

0:06:100:06:13

sure there is no cross-contamination. Suited up,

0:06:130:06:16

Sandra starts on the first consignment -

0:06:160:06:18

a product that needs checking before being allowed through the port.

0:06:180:06:22

Liam here's got a container from Japan,

0:06:220:06:26

and following Fukushima, there is a need to sample for radiation,

0:06:260:06:33

so we sample...

0:06:330:06:34

I think it's 5% of any Japanese products that come through.

0:06:340:06:38

These samples are packaged and sent off.

0:06:380:06:41

Next up, a shipment of Canadian seafood is being scrutinised.

0:06:420:06:47

We have shrimp and lobster, beautifully packaged,

0:06:470:06:51

beautifully presented. I will do a sample.

0:06:510:06:55

The lobsters are sent to the laboratory as part

0:06:550:06:58

of a regular check for any microbiological contamination.

0:06:580:07:02

Sandra has concerns about some apple snails,

0:07:020:07:05

a Vietnamese delicacy being imported to the UK.

0:07:050:07:08

We are going to look for the cooked apple snail

0:07:080:07:13

because we've tested this product previously and we've found

0:07:130:07:18

Escherichia coli, a dangerous microbial pathogen, in there.

0:07:180:07:22

Samples collected, the next task is to send them

0:07:240:07:26

back to the lab for analysis.

0:07:260:07:29

We'll bring you the results of those tests later in the programme,

0:07:290:07:32

when we'll also be heading to Kent, where Trading Standards officers

0:07:320:07:35

are carrying out an investigation into potentially dangerous

0:07:350:07:39

food products that have already found their way onto the shelves.

0:07:390:07:43

You've bought a brand-new TV and a flash new DVD player

0:07:470:07:50

to watch your favourite TV shows and films in high-definition.

0:07:500:07:54

But which cable should you buy to connect the two devices

0:07:540:07:58

to ensure you get the best possible picture and sound?

0:07:580:08:01

Well, you can pay £3.99 or £89.99. So which do you choose?

0:08:010:08:06

Now, I'm no film buff, Sophie,

0:08:070:08:09

but when I watch a movie on TV, I don't want this.

0:08:090:08:12

I want this -

0:08:120:08:13

pin-sharp pictures and perfect stereo sound.

0:08:130:08:16

And if that film's playing through a DVD player, Blu-ray or games

0:08:160:08:19

console, you're going to need one of these in order to get it -

0:08:190:08:23

a High-Definition Multimedia Interface,

0:08:230:08:25

more commonly known as an HDMI cable.

0:08:250:08:28

With so many cables on the market offering

0:08:280:08:30

everything from 24-Carat gold-plated connectors to V-Grip

0:08:300:08:33

technology, how do I know which one's the best to buy?

0:08:330:08:36

What you want is the best possible quality picture

0:08:360:08:39

and really crystal clear-sound.

0:08:390:08:42

The shop is saying you need an expensive cable to link the two

0:08:420:08:46

together to achieve those things.

0:08:460:08:48

Do you really need that cable?

0:08:480:08:50

Let's find out.

0:08:500:08:52

Yes, we're taking our Test House to the movies. The audience?

0:08:520:08:56

11 avid movie fans each belonging to local film clubs.

0:08:560:09:00

For the purposes of our test, we've connected up one of these

0:09:000:09:03

televisions with one of the most expensive HDMI cables we could find.

0:09:030:09:06

It costs £89.99 and claims to have gold-plated connectors

0:09:060:09:10

and give the purest images.

0:09:100:09:11

On the other television, we've used the cheapest we could find -

0:09:110:09:15

a £3.99 cable.

0:09:150:09:16

Everything else is identical - identical TVs,

0:09:160:09:19

Blu-ray players and Blu-ray Discs.

0:09:190:09:21

We're not going to tell our fans which screen is which,

0:09:210:09:24

so they'll have to judge for themselves.

0:09:240:09:26

Hopefully, the more expensive one will give more clarity of image

0:09:260:09:29

throughout and also more clarity of sound.

0:09:290:09:31

You sort of think, well, more expensive is going to be better,

0:09:310:09:34

but I'll sort of reserve judgment, somewhat.

0:09:340:09:37

You would expect the more expensive cable to be better quality,

0:09:370:09:42

sharper, brighter.

0:09:420:09:44

Next, to reveal what film we'll be showing.

0:09:440:09:46

For these fanatics, it's got to be nothing but the best.

0:09:460:09:49

In fact, it's considered by some to be greatest movie ever made.

0:09:490:09:53

Rosebud.

0:09:590:10:00

No, not that one. This one - Lara Croft: Tomb Raider.

0:10:030:10:07

THEY GROAN

0:10:070:10:09

Well, if you are going to watch anyone in full HD,

0:10:090:10:11

it might as well be Angelina Jolie.

0:10:110:10:14

Right, let's get started.

0:10:140:10:16

We show our film fans a range of scenes, including live action

0:10:160:10:19

to test the picture and dialogue scenes to test the sound.

0:10:190:10:23

Which one will they think is connected with the more

0:10:230:10:25

-expensive cable?

-Can I look closer?

-Yeah.

0:10:250:10:28

I can't distinguish between the visuals at all.

0:10:300:10:33

It's almost impossible to say which is better.

0:10:330:10:37

I don't know if we've really heard the footsteps as clear as this one.

0:10:370:10:41

I can't hear the difference. Maybe you've got better hearing than me!

0:10:410:10:45

It would be a guess between the two, so I'm going to plump for the left.

0:10:450:10:48

The expensive cable might be on the screen on the right.

0:10:480:10:52

I picked the one on the right.

0:10:520:10:54

I really can't tell the difference between the two.

0:10:540:10:57

Mixed opinions all round. Two chose the left screen,

0:10:570:11:00

six chose the right screen

0:11:000:11:02

and three of our film buffs couldn't spot any difference between the two.

0:11:020:11:05

So which one was it? Could you tell at home?

0:11:050:11:08

Find out later.

0:11:080:11:09

Prams and buggies. Anyone with small children needs one.

0:11:140:11:18

And it's become quite an industry, with parents spending more

0:11:180:11:21

than £200 million on them every year.

0:11:210:11:25

And these sleek new designs have certainly come a long way

0:11:250:11:28

since the first fully foldable pushchair was launched in the 1960s.

0:11:280:11:33

But that doesn't mean things don't go wrong today,

0:11:330:11:36

as Lynn Faulds Wood knows all too well.

0:11:360:11:38

'Welcome to Watchdog. In tonight's programme...

0:11:420:11:45

'All these people have written to us...'

0:11:450:11:47

Imagine that this carrot is a child's finger.

0:11:480:11:51

As the frame collapses,

0:11:510:11:53

you might pull on the handle to stop that happening.

0:11:530:11:56

It's been a bumpy road for our baby buggies.

0:11:580:12:01

I was banging on about them in the 1980s and decades later,

0:12:010:12:05

they were still featuring on Watchdog.

0:12:050:12:07

I was walking to me mum's house and as I bumped down a curb

0:12:090:12:12

to cross the road, the pram just completely snapped.

0:12:120:12:15

So why are we still talking about buggy safety today?

0:12:160:12:20

After all, it's not as if we haven't had plenty of time to

0:12:200:12:23

get them right.

0:12:230:12:25

The first pram was actually developed in the 18th century

0:12:260:12:29

but it wasn't till the end of the 19th

0:12:290:12:32

that they began to be mass-produced.

0:12:320:12:34

This pram, on sale in the 1880s, was one of the first to allow

0:12:340:12:38

babies to lie down.

0:12:380:12:40

The first thing we notice is that, actually,

0:12:400:12:43

they did care about safety because there are straps but

0:12:430:12:45

they don't look desperately sensible and I don't think much thought

0:12:450:12:49

has been given to the way they would actually work once you've got

0:12:490:12:52

the child there. But the other thing you immediately notice is no brakes.

0:12:520:12:56

So if you stopped with this on the side of a hill,

0:12:560:12:58

you were really in trouble.

0:12:580:13:00

This model might look like it's from a Batman film,

0:13:050:13:08

but by the 1920s, prams were made deeper to stop babies falling out.

0:13:080:13:13

Doctors were advising that children got more fresh air,

0:13:130:13:16

so more time in the garden in their pram, more walks, and people felt

0:13:160:13:20

that children should be both more secure in the pram and warmer.

0:13:200:13:24

For the first time, prams were being built with a basic

0:13:250:13:27

brake as well as a handy brolly holder!

0:13:270:13:31

But by the 1960s, there were concerns that a deep body design

0:13:310:13:35

could actually smother a child.

0:13:350:13:38

# Baby love

0:13:380:13:39

# My baby love... #

0:13:390:13:41

So they went away back to the more or less Edwardian, late Victorian

0:13:410:13:45

idea of a shallower body, which was higher up in the air.

0:13:450:13:50

We also have a foot-operated brake round at the front

0:13:500:13:53

which is much easier to operate.

0:13:530:13:56

The '60s also saw the introduction of the first

0:13:560:13:59

technical safety standard, in '67.

0:13:590:14:02

Stability was very important so that the child did not have

0:14:020:14:07

the ability to make the product fall over.

0:14:070:14:11

Harnessing and retention of the child in the product was also

0:14:110:14:15

very important. The other major issue in those days was braking.

0:14:150:14:18

But the old style pram had had its day.

0:14:220:14:25

In the 1960s, Maclaren introduced the first fully foldable pushchair.

0:14:250:14:30

And by Jubilee year in 1977,

0:14:300:14:32

the company was turning out 20,000 a week.

0:14:320:14:36

# God save the Queen... #

0:14:370:14:39

Now buggies would have to balance the need for safety

0:14:390:14:42

with the need for convenience and portability.

0:14:420:14:45

So standards were expanded to cover these new, smaller, folding

0:14:450:14:49

pushchairs and the risks potentially caused by moving and foldable parts.

0:14:490:14:55

The most common concern?

0:14:550:14:57

So-called finger traps.

0:14:570:14:59

As Watchdog exposed in 1989, some children had lost

0:14:590:15:04

parts of their fingers in this Mothercare pushchair.

0:15:040:15:08

The locking device is right here,

0:15:080:15:10

where a child might rest his hands on it or they could play with

0:15:100:15:13

these lovely, jangly safety rings and the whole thing can collapse.

0:15:130:15:17

Now, if that happens, you can grab on the handle to stop it

0:15:170:15:21

collapsing and here's how bits of the finger have got chopped off,

0:15:210:15:25

if I use that carrot as a finger.

0:15:250:15:27

Mothercare changed that faulty design.

0:15:270:15:30

But as European standards require the agreement of all member

0:15:300:15:33

countries, with new models coming onto the market all the time,

0:15:330:15:37

it can be hard for safety organisations to keep up.

0:15:370:15:41

There are so many developments because everybody is trying to

0:15:410:15:46

give the consumer what they want and the consumer these days wants

0:15:460:15:50

ease of use - to get on buses, to get on trains, to get in cars,

0:15:500:15:54

and therefore, that leaves the standards people

0:15:540:15:57

lagging behind all the time.

0:15:570:16:00

We cannot keep pace with modern developments.

0:16:000:16:03

But even when a product does meet high safety standards

0:16:030:16:06

before it goes on the market, it doesn't mean things can't go wrong.

0:16:060:16:11

The baby buggy maker Maclaren is at the centre of a safety scare.

0:16:140:16:18

It's had to issue urgent advice

0:16:180:16:20

and repair kits for around a million pushchairs in America.

0:16:200:16:23

It follows reports that 12 children had to undergo

0:16:230:16:26

amputations after getting their fingertips caught in the hinges.

0:16:260:16:30

Days later, Maclaren agreed to issue the same special

0:16:300:16:33

covers for the buggy's hinges in the UK.

0:16:330:16:37

Then, three years later, it was Cosatto's turn

0:16:370:16:40

to take action on a small number of their products.

0:16:400:16:43

This is one of their most popular models. It's called the Giggle.

0:16:430:16:46

Except, what follows isn't the least bit funny.

0:16:460:16:50

After Watchdog investigated their Giggle in 2013,

0:16:500:16:54

Cosatto issued a safety notice on a faulty bracket,

0:16:540:16:58

causing some buggies to collapse.

0:16:580:17:01

The worst thing is, what if he'd been a little bit younger?

0:17:010:17:04

He could have literally come out the pram.

0:17:040:17:07

This time, the fault was due to a manufacturing problem and the

0:17:070:17:11

smallish numbers of products affected are no longer on sale.

0:17:110:17:15

After Watchdog's report, Cosatto agreed customers

0:17:150:17:18

could return their pushchairs to be strengthened at no extra cost.

0:17:180:17:23

From improving testing standards to putting right design flaws

0:17:230:17:27

and manufacturing faults, it's fair to say

0:17:270:17:29

that when there is a problem, the industry does work hard to fix it.

0:17:290:17:34

So will that be the last we hear about the safety of our buggies?

0:17:340:17:38

It is very difficult to guarantee anything is 100% safe.

0:17:380:17:42

Is your car door 100% safe for children's fingers?

0:17:420:17:44

Is your door in the house 100% safe with fingers?

0:17:440:17:47

It's impossible.

0:17:470:17:49

We try, within standardisation, to cover as many areas as we can

0:17:490:17:54

and we try very, very hard to make the products as safe as possible.

0:17:540:17:58

With petrol and diesel costing as much as £1.50 a litre,

0:18:040:18:08

you might be thinking it's time to go green and go electric.

0:18:080:18:12

With no tax, no costly fuel and free parking in certain areas,

0:18:120:18:16

it is tempting but these cars are expensive.

0:18:160:18:20

So does it work out in the end?

0:18:200:18:23

With me now is Emma Butcher, from What Car?

0:18:230:18:25

So as far as electric cars are concerned,

0:18:250:18:28

how much are they nowadays?

0:18:280:18:29

Well, you're looking at around £25,000 for an entry-level electric

0:18:290:18:33

car on average, and that includes a £5,000 grant from the government.

0:18:330:18:38

So they're not cheap.

0:18:380:18:39

You're probably looking at about double the price

0:18:390:18:42

for a similar-sized petrol car.

0:18:420:18:44

But in terms of the price, as the technology improves,

0:18:440:18:47

-do you think that the cost will go down?

-Absolutely.

0:18:470:18:50

So the biggest cost of an electric car is the battery.

0:18:500:18:53

Battery manufacturers reckon that by about 2020, we could see those

0:18:530:18:57

costs halved, so electric car costs will come down significantly.

0:18:570:19:00

Obviously, it's green, it helps the environment,

0:19:000:19:03

but do you get your money back?

0:19:030:19:04

For the right lifestyle, they can be a really fantastic choice,

0:19:040:19:09

so they're much cheaper to fuel, obviously, than a standard fuel car.

0:19:090:19:14

If you charge overnight,

0:19:140:19:16

if you have that facility to do that at home,

0:19:160:19:18

you're looking at about £1.50 for a full battery charge, then you're also

0:19:180:19:22

looking at reduced servicing costs because there are fewer moving parts.

0:19:220:19:26

You don't have to have oil filters changed and things like that.

0:19:260:19:29

-So yeah, the savings can really stack up.

-What about longer journeys?

0:19:290:19:33

How far can you go in an electric car?

0:19:330:19:35

Well, we reckon that you're probably looking at a range

0:19:350:19:38

of about 90 miles in good weather.

0:19:380:19:40

In the winter, the range drops to about 60 miles,

0:19:400:19:43

-so you need to be careful.

-You've driven them. Are they good to drive?

0:19:430:19:46

They're fantastic to drive.

0:19:460:19:48

The torque is instant, there are no gears to interrupt power

0:19:480:19:51

and it's just so quiet and smooth.

0:19:510:19:52

-Yeah, a really good experience.

-Emma, thank you.

0:19:520:19:55

Earlier, we looked at the cables at the back of our TVs.

0:20:000:20:03

We asked some film fanatics

0:20:030:20:05

to watch a film in high-definition on two screens.

0:20:050:20:09

One was connected with an expensive cable, the other with a cheap one.

0:20:090:20:13

Could they tell the difference? Time to find out.

0:20:130:20:16

Yes, one cable cost £89.99, the other just £3.99.

0:20:180:20:22

As for the 11 film fanatics,

0:20:220:20:25

two thought the left screen was connected by the expensive cable,

0:20:250:20:28

six chose the right screen

0:20:280:20:30

and three of our film fans couldn't spot any difference between the two.

0:20:300:20:34

So which one was it?

0:20:340:20:36

Although most of our fans chose the screen on the right,

0:20:360:20:39

the expensive cable was actually connecting the one on the left.

0:20:390:20:42

-Wow!

-I'm just shocked.

0:20:420:20:44

It's quite surprising that the one on the left is supposedly

0:20:440:20:48

the better quality one

0:20:480:20:50

-because I thought it was just slightly the one on the right.

-Wow!

0:20:500:20:54

Yeah, not worth it!

0:20:550:20:56

We all preferred the right one, the cheaper one!

0:20:560:20:59

So why did our film buffs find it so hard to work out which was which?

0:21:000:21:04

Time to get technical.

0:21:040:21:06

So let's look at the wave forms that are actually sent down our cables.

0:21:060:21:11

Now, these are digital wave forms and a wave form that's sent

0:21:110:21:14

digitally looks a bit like castle battlements. It will go up and

0:21:140:21:18

down and up and down and maybe down for a bit and then up for a bit.

0:21:180:21:23

So no matter how expensive the cable, as long as it's made of metal

0:21:230:21:26

and it conducts electricity, that signal will be transferred.

0:21:260:21:30

And although a more expensive cable benefits from being stronger

0:21:300:21:33

and more robust,

0:21:330:21:34

if a signal did become distorted by a faulty connection

0:21:340:21:37

or a damaged wire, according to Professor Webb, your TV would

0:21:370:21:41

still deliver exactly the same picture and sound.

0:21:410:21:44

Now, clearly, it's different from the one at the top

0:21:440:21:47

but equally, we can work out what it should have been just by looking

0:21:470:21:50

at it, and a television can do the same.

0:21:500:21:53

But with even the cheapest cable very unlikely to do this,

0:21:530:21:57

do you really get better picture or sound if you pay extra?

0:21:570:22:00

Absolutely not. There's no need for a more expansive cable.

0:22:000:22:04

As long as the signal gets from one end of the cable to the other,

0:22:040:22:08

everything is fine.

0:22:080:22:09

And that works perfectly well, as long as the cable

0:22:090:22:12

is a conductor of electricity.

0:22:120:22:14

He's not just saying that, you know. He can prove it, too.

0:22:140:22:17

First, he cuts the wires inside this HDMI cable

0:22:170:22:20

that carry the picture image.

0:22:200:22:22

So here, we have a cable that is working. We can see a picture

0:22:220:22:25

and if I now let these two ends fall apart, away it goes.

0:22:250:22:30

He then inserts a number of different metal objects

0:22:300:22:33

into the gap to see if the signal still transmits.

0:22:330:22:36

First, a gold ring.

0:22:360:22:37

So let's take our cut wire...

0:22:370:22:39

..and put the two ends onto different parts of the wedding ring.

0:22:400:22:44

There we go. So that signal is travelling through my wedding ring

0:22:440:22:50

on its way to the television.

0:22:500:22:52

Next, a steel barbecue skewer.

0:22:520:22:55

If I touch up these two leads, there we have it.

0:22:550:23:00

A kebab stick is carrying our TV signal!

0:23:000:23:03

OK. Well, those were solid metal.

0:23:030:23:06

What about something that isn't even solid metal?

0:23:060:23:08

So here's a little bit of kitchen foil, metal kitchen foil.

0:23:090:23:15

Let's see if we can get our signal to pass through the foil.

0:23:150:23:19

And look! The picture has come back again.

0:23:200:23:23

OK. We're convinced.

0:23:230:23:24

As long as your HDMI cable conducts electricity

0:23:240:23:27

and has been bought from a reputable source, the picture quality

0:23:270:23:30

and sound quality will always be the same. But what about

0:23:300:23:33

the other benefits, some of the more expensive cables offer?

0:23:330:23:37

Well, the manufacturer of the expensive cable told us

0:23:370:23:40

their product is built to exceed industry standards, is supported

0:23:400:23:43

by a limited lifetime warranty and contains premium materials

0:23:430:23:47

to ensure reliability and performance for the life of the product.

0:23:470:23:50

The more expensive ones tend to work, even if they're mistreated.

0:23:520:23:56

So unless you're the person that goes about and enjoys tying

0:23:560:23:59

knots in their cables, a cheap HDMI cable will do the job perfectly

0:23:590:24:04

well for you and there's no need for one of these - the expensive items.

0:24:040:24:08

Earlier, we saw how in Southampton, the Port Health Authority

0:24:130:24:17

stop and check shipments on a daily basis to make sure the food

0:24:170:24:21

being brought into the country is safe to eat.

0:24:210:24:23

They sent off various samples to the lab for testing.

0:24:230:24:26

A few days later, the results are in.

0:24:260:24:29

The samples included some apple snails, a Vietnamese delicacy.

0:24:300:24:35

So what we do when we receive the food

0:24:350:24:37

is we first of all have to take out a sample and mush it up.

0:24:370:24:41

Bacteria aren't going to just jump off the snails

0:24:410:24:43

and onto the agar plate. We've got to release them

0:24:430:24:46

from the food into a format that we can test on agar plates.

0:24:460:24:49

Agar plates are used to help grow bacteria.

0:24:490:24:51

If there's any present, it will soon reveal itself.

0:24:510:24:54

We literally mash the snails up with some liquid,

0:24:540:24:57

which releases the bacteria, and we can then take that liquid

0:24:570:25:00

and put it onto agar plates.

0:25:000:25:02

And then those agar plates will go into incubators,

0:25:020:25:05

sometimes for a day, if it's things that grow quickly, sometimes

0:25:050:25:08

for five days or more for slow-growing bacteria

0:25:080:25:11

and other organisms.

0:25:110:25:13

And then we get them out and have a look at them.

0:25:140:25:16

The team then tested the plates for Salmonella and E. coli -

0:25:160:25:20

bacteria that could cause food poisoning.

0:25:200:25:23

On this occasion, both these tests proved negative.

0:25:230:25:26

So when we looked at all the results we've got from the apple snail

0:25:260:25:29

testing together, we don't feel that any of them

0:25:290:25:32

indicate a significant problem for public health, particularly

0:25:320:25:35

when you take into account the apple snails are due to be cooked.

0:25:350:25:39

So we're happy with the results we've obtained for these samples.

0:25:390:25:43

With the Canadian prawns, lobsters and Japanese tea

0:25:430:25:46

we saw earlier also testing negative for any dangers to health,

0:25:460:25:50

it's good news for the importers. The shipments have passed

0:25:500:25:53

Port Authority checks and are safe to move into the market

0:25:530:25:56

and be consumed.

0:25:560:25:58

Meanwhile, Trading Standards officers in Kent are investigating

0:25:580:26:01

another imported food product suspected of being dangerous

0:26:010:26:05

that's already made it onto the shelves.

0:26:050:26:07

Today I'm heading to a shop to follow up a sample

0:26:070:26:11

of some cornflour, which we recently had tested

0:26:110:26:15

as it had... Excess levels of aflatoxins were found in it.

0:26:150:26:19

Aflatoxins are linked to cancer, so I'm just heading back

0:26:210:26:27

to the shop to take another sample for the laboratory.

0:26:270:26:30

Alex arrives at the store to seize the second sample

0:26:300:26:33

of potentially carcinogenic cornflour.

0:26:330:26:36

Alex wastes no time finding the items he's got concerns about.

0:26:370:26:41

All these are from the same batch of cornmeal, so they're all

0:26:410:26:44

processed at the same time, so I'll sample all three of these bags.

0:26:440:26:49

As Alex bags and tags the products, the owner arrives on site.

0:26:500:26:54

With the paperwork complete, Alex pays for the goods

0:26:540:26:57

and takes them to the lab for testing.

0:26:570:26:59

OK. Thank you. Bye.

0:27:010:27:03

Aflatoxins themselves are a very, very potent carcinogen in terms

0:27:070:27:11

of it affecting the liver and that's why the legislative limits are set

0:27:110:27:15

at two parts per billion parts of food,

0:27:150:27:17

so it's a very, very low level.

0:27:170:27:19

The cornflour is separated, weighed out

0:27:200:27:23

and mixed with a solution to strip out any toxins present.

0:27:230:27:27

We can measure individual toxin concentrations and give a total

0:27:270:27:30

and we can then compare those results against the legislative

0:27:300:27:33

limits to determine whether it passes or fails.

0:27:330:27:36

And this is the machine that does the calculations.

0:27:360:27:39

It analyses the toxins present...

0:27:390:27:41

..and displays the results on a graph.

0:27:480:27:50

The peaks show the levels of aflatoxin present.

0:27:500:27:52

So unfortunately, I've had the test report

0:27:520:27:55

and it's shown that there are excess levels of aflatoxin

0:27:550:27:57

in the sampled cornmeal.

0:27:570:28:00

The next course of action would be to notify

0:28:000:28:02

the importer of the result

0:28:020:28:04

and also the Food Standards Agency.

0:28:040:28:05

The likely course of action - this product will be

0:28:050:28:08

withdrawn from the market while we continue with our investigations.

0:28:080:28:11

The cornflour is now the subject of an investigation

0:28:110:28:15

and proceedings are ongoing.

0:28:150:28:16

Hopefully, that's one potentially harmful product you

0:28:160:28:20

won't need to worry about seeing on the shelves in the future.

0:28:200:28:23

0:28:310:28:33

That's all for today. Thanks for watching.
