We process RTE imitation crab.
When we do our (listeria, E.coli, Salmonella, Coliform, TPC) testing, we currently do a composite test of 3 bags (per 36 cases) which is about 30 tests per day.
We're looking to cut lab costs and wondering if we could do a composite of 6 bags (per 72 cases) which would drop our testing about in half.
It would be the same about of product being tested, just less tests. Which would save us a LOT of money per year. But we can't find any reference as to how many tests we should run.
