Hello I have a question about the manufacturing of product with allergens in a production plant.
1. If a plant produce different products but some of the products contains allergens, considering that the product with allergen is produce with dedicated equipment/instruments and in a dedicated room, is it mandatory to write on the label of all product may contain allergen?
If I understand you correctly, you are producing a product that contains allergens, is produced in a dedicated space with dedicated equipment. Do you have to label the product with the allergens it contains? Yes, absolutely.
2. If an equipment can be used for a product with no allergen and also a product with allergen but the equipment is properly cleaned with a validated method. Is is mandatory to indicate of the label of the product that is not containing allergen "may contain Allergen".
"may contain" statements are allowed (in the US at least). But it does not absolve you of legal ramifications if a consumer issue happened where there was indeed an allergic reaction to a product.
However, if your production equipment is cleaned as you say, there should not be a problem labeling it with no allergens.
3. Can we produce in the same room but on dedicated equipment a product that contains allergen and another product that does not contain allergens or it should be in two different room?
It all depends on your allergen management system and the construction of your "room". Ideally, it should be in two different rooms.
We have three cookie lines in one space. We produce different varieties of cookies with different allergens or gluten free at the same time.
Because of the layout of the space, there is sufficient room between the lines to prevent anything other than deliberate allergen cross contact.
It would be helpful to know what kind of product(s) you produce and what allergens you have.
