Dear Foodworker,
Some interesting (and brave) words.
used to do store audits for a major C&C company and I always had problems persuading them to segregate packed ready to eat and raw frozen products
What does C&C mean ? Cooked and Chilled ?
I am not surprised you had problems although it may relate to specifics. Although it is intuitively logical after (hopefully) using dedicated freezers for RTE products to then maintain the separation for the packed frozen items, i think, as you intimate, that many (most?) processors simply regard the chance of significant health risk from frozen packaged products "touching" to be negligible. And the same comment with respect to frozen storage = CCP in general. i agree some auditors do not readily accept such conclusions until (joyfully) crushed by extensive supporting references.
Other than the (FSA so far?) un-followed-up telegraph item, do you know of any published validation of these suggested fears in the literature for seafood (or any other single product for that matter)?. i cannot remember ever seeing a documented incident for seafood from this cause or any official statement spelling out a significant risk / necessity of absolute separation of frozen
packaged raw / RTE seafood. [quite happy to be proven wrong though

]. If one is talking about mingling frozen packaged seafood / chicken that would be a different issue IMO (and more likely [i think] to be validatable). I hv always considered the latter scenario as a strict audit no-no thks to raw chicken's well-validated "fellow-passengers". Used to be a frequent easy rejection but less common these days (post
