In the first episode, Alice Roberts reveals that many of us are taking home a food poisoning bug from the supermarket. Campylobacter is the most common cause of food poisoning in the UK.

Tom is on a mission to improve our cooking skills one dish at a time. This time he's in Poole to help a viewer who just can't seem to cook fish without ruining it.

With the help of food scientists, Sean Fletcher is pulling apart the ingredients in some everyday foods to find out - this time it's pasta.
