hygiene procedures, hygiene training

[meggi]

Помогите, пожалуйста разобраться со значением hygiene в приведенных ниже контекстах. Всегда ли это гигиена труда? Или где-то надо перевести как санитарно-гигиенические (как правильнее перевести hygiene procedures?)
1)Does the farm have documented hygiene instructions?
The hygiene instructions are visibly displayed. The instructions must at least include:
- the need for hand cleaning;
- the covering of skin cuts;
- limitation on smoking, eating and drinking to certain areas;
- notification of any relevant infections or conditions;
- the use of suitable protective clothing.

2)Have all persons working on the farm received basic hygiene training according to the hygiene instructions?

3)Are the farm’s hygiene procedures implemented?
Workers with tasks identified in the hygiene procedures must demonstrate competence during the inspection
