Bacteria that cause food poisoning can be on everyone - even healthy people. The bacteria can be spread to food when touching ones nose, mouth, hair or clothes, and then food.
Good personal hygiene and safe food handling practices can prevent food poisoning.
Keep your kitchen surfaces clean and wash your hands often to help prevent the spread of bacteria.
You should buy food from food-handling staff who take hygiene seriously and practise safe food handling.
