Anne,
You should continue performing the histamine testing every quarter. Even with frozen product, temperature variances inside the cold storage could trigger the production of biogenic amines (e.g., histamine). For the actual test, you need 250g for the HPLC method and 150g for the ELISA method.
Representative sampling information should be done in accordance with the FAO/WHO Codex Alimentarius standards (http://www.codexalimentarius.net/web/standard_list.jsp). For example, CODEX Standard 70 - Sampling Plans for Prepackaged Foods (1969) (AQL-6.5) (Ref. CAC/RM 42-1977).
Regards,

Subject:
I have a question regarding Albacore tuna histamine testing and HACCP. Page 98 of Hazards guide says you need to do quarterly histamine testing on a representative sample of the raw material. How do you determine what that sample amount should be? If you purchase only two months of the year and hold the product in cold storage, would you still be expected to continue quarterly sampling when you send lots out for production when you have already tested those lots?
thank you
