I recently stumbled upon a brief training material on washing (interior and exterior) of food delivery van/truck should be carried out outside the food production premises.
We usually washed outside the loading area.
Is there any specific criteria, e.g.
1. must be washed outside the production perimeter?
2. Or a certain metre/kilometre/miles away?
3. must be done by external contractors?
4. Time segregation of actiivity e.g. wash at the end of loading/off loading
Please comment and let me know what is the most appropriate method without having to "put in more money'.
