X-Ray - Series 9 - Episode 23

It's estimated that one in ten cigarettes smoked in the UK is imported illegally, and that the trade diverts money from the public purse and funds organised crime. Rachel Treadaway-Williams meets the customs officers whose job it is to clamp down on this illicit trade and X-Ray gets exclusive behind the scenes at Cardiff airport where some travellers fall foul of duty controls. Meningitis is a notoriously difficult disease to diagnose, with wide ranging symptoms. The Five Minute Medic is in Llanelli, finding out how much people know about the illness, and Lucy gets some advice on how to recognise the warning signs. There seems to be a new cleaning product advertised almost every day - but do the most modern and sophisticated products lead to a cleaner house? Lucy goes back to the 1950's to take a look at the science behind more old fashioned cleaning remedies. And in Portland Street, it's the children and teenagers' turn to learn to cook, with the help of one of Wales's best known chefs. Michelin starred James Sommerin shows the street's young people how to make his grandmother's chicken casserole and a rice pudding. But will they manage to put their lesson into practice and feed their own families?
