The harmonized audit requires a listing of equipment (2.7.1) that has the potential to come into contact with the crop, and for each piece of equipment a maintenance record.
Just how detailed of a record do they want?
Anytime there is a repair, cleaning, or fluid change there should be a record of this task. The auditor will look at the equipment for signs that there could be a issue, such as an oil or fluid leak under the equipment. If they see an issue they will then ask to see the maintenance record for that piece of equipment. This falls under the “are in good repair and are not a source of contamination of produce” section of standard 2.7.2. Remember, this is only for equipment that will go out into the field or production area.
