Hi All I have a specific question for the Forum. I was asked for specific limits for microbiological testing of hygiene levels (cleaning) of bulk containers used for different products. My question is seeing that most products have a bacterial count limits of < 1000 cfu's p/ml or p/g, and < 100 cfu's p/ml or p/g of fungi/yeasts ,what should be the cleaning level that should be accomplished? What type of method should I use RODACs or swabs? Cleaning is done by high pressure water at Temperatures +/- 70 deg. C, plus TEEPOL which is but a soap, or should I rather call it "CHEAPOL", I suggested that a disinfectant soap would straight off be a better choice but motivation would obviously be required. Should there be a difference in the type of soap/disinfectant used for more difficult product (i.E. ointments/creams)? Please let me know your valued opinions soon. Thank you all for all the help so far provided.
