Food hygiene on the wards.
A PROBLEM THAT IS OFTEN OVERLOOKED OR SIMPLY NOT GIVEN ENOUGH ATTENTION: the food served to patients from the kitchen is not sterile. If food is allowed to stand at room temperature for a long time, both in the case of food cooked for lunch and of food intended for supper which has been previously chilled, there is the possibility of massive spore germination or of dangerous toxin formation. Therefore regulations on how to handle food and beverages (e.g. tea) must be set out in the infection control policy, and checks carried out to monitor compliance with the rules relating to temperature checks, duration and type of storage, need for reheating, etc. Making staff aware of the issues involved is of paramount importance. These include monitoring hygiene standards in the ward kitchen, formulation of a cleaning policy, periodic bacteriological checks (not only of workstations but also of the dishwasher results), whenever possible the use of disposable cloths for working surfaces and equipment, changing cleaning cloths at least once daily and hygienic hand disinfection before and after handing out food. Foodstuffs brought in by visitors represent a special hygienic and organizational problem because in many cases they already have a high baseline microbial count. Visitors must be made aware that, for example, slices of cake left in the patient's room and often eaten only hours later can pose a risk of infection.In summary, the following principles of food hygiene must be observed on the wards:Maintenance of the cold-hot chainNot only reheat food, but ensure it is well heated throughout Avoid situations giving rise to spore germination in foodstuffs brought in by visitorsCleanliness and minimal contamination of kitchen worktopsCleanliness of crockery and kitchen towels Do not allow food to stand at room temperature for a long time, in particular desserts and confectionery A standard policy must be enforced to define the hygienic status and organization for food distribution for ward kitchens too.
