We have several HACCP variation tables available. Below you can see the HACCP variation table that we have composed for Pathogenic . Since this table is very extensive, we recommend using the download below to view the table properly.

What are Pathogenic bacteria?

Pathogenic bacteria can cause dangerous cases of food poisoning and therefore should not be present in food at all or should not exceed a specific number per gram of food.
