Hand washing is enforced and monitored in chilled food production according to the rules described on our poster:
The method depicted on this poster was developed through quantitative study and assessment by *Birmingham City Hospital Infection Research Laboratory, UK.
Use of Gloves
1. Some food handlers choose to wear gloves because they may not wish to handle a certain food type, e.g. pork.
In this case gloves are managed according to the rules stated on the poster.
2. A glove is just another food contact surface.
Like your hands, gloves also can become dirty and covered with bacteria. They are not a substitute for hand hygiene.

3. Gloves encourage a false sense of security in food handlers and can result in reduced washing frequency, leading to a build-up of contamination on the surface.
Unwashed hands will feel unpleasant, encouraging more frequent washing.
In one study a few participants said that they washed their hands before and after glove use, but most said that consistent handwashing during glove use was not a common practice. Several participants from both groups said that they found glove use to be a nuisance: “Gloves are difficult to deal with because you have to take them off a lot; they get really dirty.”

4. Glove use may lead to less safe hand washing practices unless hand washing regimes are enforced as stated on the poster

Nailbrushes are not used since they can themselves become vehicles for contamination
- The use of nailbrushes can create aerosols spreading contamination.
- Nailbrushes are not user-friendly, making it unlikely that they will actually be used
- To clean around and under the free edge of nails the tips of the fingers are rubbed energetically in a circular motion in the palm of the other hand, and vice versa (fig 8)
