It is not always possible to get definitive evidence that a piece of equipment is suitable for food contact nd complies with whatever legislation that aapplies in different countries. Sometimes it could be the age of the item aand any documentation was lost years before the legislation existed or it could be tht the supplier is unable to provide it.
The BRC Standard recognises this and allows you to justify using it following a risk assessment.
This is an extract ffrom the Interpretation Guidelines:
Where evidence to confirm the suitability of food contact equipment is not available, and the contact material is not a recognised food-safe material (such as stainless steel), a documented risk assessment should be carried out to justify its use and ensure that it is not a food safety risk. The risk assessment must consider factors such as:
•the nature of the food contact surface and its known characteristics
•the length of contact time with the food
•the nature of the food and its potential for contamination (e.g. fatty foods are often at increased risk from migration of contaminants from plastic materials).
