Food hygiene is about one thing, preventing others from becoming unwell when they consume food. The 4Cs of food hygiene; cleaning, cooking, chilling and cross contamination make all the difference. The Food Standards Agency state that anyone who may touch food, come into contact with surfaces where food is prepared; even those in the same room where food is being prepared, count as a food handler. All food handlers are at risk of contaminating food, especially the ones without any training.
