Around half of all teenagers in the UK are putting themselves at risk of food poisoning because they don't wash their hands before eating or after visiting the toilet, a new survey indicates, To coincide with National Food Safety Week, researchers from the Food and Drink Federation (FDF) conducted a survey of over 500 people aged between 11 and 19 about their hygiene and eating habits. Their survey showed that 57 percent of teenagers admitted to not always washing their hands after visiting the toilet or before lunch at school. Of these, over two-thirds ate lunch, such as sandwiches or a burger, with their hands.
Furthermore, 40 percent of those who do wash their hands do not always use soap. And 75 percent said they dry their hands on their clothes when in a hurry—damp hands spread around 1,000 times more germs (病菌) than dry ones. Excuses that teenagers gave for not washing their hands ranged from not having enough time (24 percent) to dirty and unhygienic facilities (26 percent) and forgetfulness (22 percent).
Food safety expert Hugh Pennington, professor of Microbiology at Aberdeen University, said, "The best news about food safety is that one doesn't have to be a rocket scientist to do it properly. The had news is that even a simple and obvious thing like hand washing—which protects incredibly well—is seen by many people as good health theory, but not actually put into practice."
Martin Paterson, deputy director general of the FDF, said that teens' hygiene habits before eating were a recipe for disaster, adding that although most know how food poisoning could occur, the majority do not take simple measures to prevent it. "Of course teenagers don't want to be overprotected," he said, "but with up to 5.5 million cases of food poisoning a year, we clearly need to keep informing people of simple food hygiene messages in fun and imaginative ways, to remind people of all ages how they can continue to enjoy their food safely."
