Enterobacteriaceae are commonly used as indicator organisms that can indicate poor hygiene practices or failure of a manufacturing process, entero results are countable, this will give you a clear picture of hygiene practices. A TVC is not a specific micro-organism but rather a test which estimates total numbers of viable individual micro-organisms present in a set volume of sample. The TVC count may include bacteria, yeasts and mould species. Both Entero and TVC belongs to indicator groups.
For example, your environment can be Listeria free but doesn't mean that is free from gram-negative organisms (Entero) which are more heat resistant. Listeria swabs won`t be enough for your cleaning validation. Not sure what are you using for verification (usually ATP swabs) but without lab validation results this won't be enough..
Try to swab before and after
- tables underneath
- scale plate underneath
- mixers
- chopping boards
