Producers are required to display clearly visible hygiene instructions either in the predominant language(s) of the workers or use pictures / pictograms. (AF 3.2.2)
Hygiene instructions are expected to include at least the following:
Inspectors are required to verify whether the hygiene instructions have been implemented and everybody on the site complies with them. (AF 3.2.4)
Hygiene instructions are there to remind workers to implement the hygiene rules. The written instructions are quite useless if the workers can’t read them. In this case, pictures would be more effective.
