We are seafood processors. we have IQF (Individually Quick Freeze) processing line for shellfish (shrimp & squid) and finfish (like tuna, amberjack and other fish). I need to validate that our process lines are not causing any cross contamination between these two types of seafoods, as allergens present in shellfish and finfish are different. we thoroughly wash our process lines after processing of each type of seafood on the equipment or you can say after each product change.
I thought we need swabs of our processing lines after washing, but when I asked the external laboratories to do so, they did not understand that what I am asking for. So, can anyone suggest the allergens testing method which is generally used for this type of validation, so that I can convey the same to the testing laboratories.
Thanks everyone in advance
