The Food Standards Agency advises people not to eat any food that has been touched or covered by floodwater or sewage.
Do not eat any produce grown on an allotment or garden that has been flooded, unless it has been cooked.
Wash your hands before and after preparing food. Using clean water, detergent, then a normal kitchen disinfectant, clean and disinfect work surfaces, plates, pans, cutlery, and plastic/glass chopping boards, before preparing food. If you have a working dishwasher, this is best for smaller items.
Throw away any food in your fridge if it has not been working for a few hours.
Do the same with any freezer food containing meat, fish or dairy, if your freezer has stopped working. You will also need to discard any food that you would eat frozen, such as ice cream.
