Industrial microbiological quality control normally covers the total count of germs, the counts of yeasts and moulds, coliform bacteria and E. colt. In special cases these investigations are complemented by the detection of Staphylococcus aureus, salmonella and listeria. 

Salmonella and Listeria are a source of numerous food borne illness. As a result, a lot of attention has been focused on these microorganisms. The effort in the Salmonella area focused on obtaining antibodies which can detect several serotypes (14-16, 61,64, 90) and shortening the assay time from 3-4 days to 1-2 days by use of more sensitive formats and enrichment protocols (74, 75, 91,92). Numerous immunoassay kits for Salmonella were developed, such as the Salmonella-Tek (74, 75), Tecra Salmonella (93) and Bio-Enza Bead (94), to name a few. More information on kits is given in section 2.9. Additional information is available for Salmonella, Listeria and other microbiological contaminants and toxins (see Table 1) in review articles and books (5, 7,11-13, 88,95-99).
