Hi Boging, 

 

It is up to you what you test for - however, I would recommend at least Listeria and ACC as your product is ready to eat. 

 

Listeria limit should be Not Detected - test for listeria spp. then if you get a hit find the speices - then this will help determine your action plan. 

 

ACC - this will depend - some countries have a set legislation on the limits - but I would suggest you do some pre clean and post clean test - you are really looking for around a 5-6 log reduction in ACC following a 2 stage cleaning process - 3-4 log from detergent and then a further 2-3 log from the disinfectant. so if you have 10^6 to start you would be maybe looking at 100 ACC in the end and this could be your limit. 

 

You could also look at doing environmental sampling for E.coli, Colifroms, Entreo, Salmonella. 

 

Please check your countries legislation and food laws - also customers may have some guidance on what they require testing. 

 

Thanks
