Remarks Bacteria of the genus Salmonella commonly occur in nature and they are the most pathogenic bacteria in cases of human diarrhoea. The transmission occurs from animal to human especially by eating of animal foodstuffs (e.g. milk products, meat products and others) and therefore human Salmonellosis refer to zoonotic diseases. Spreading of Salmonella is favoured by insufficient cooling of foodstuffs and lead to rapid proliferation of these bacteria in foodstuffs. Because of the ubiquitous environmental circulation Listeria can occur in almost all raw foodstuffs like meat, poultry, seafood, ice cream, vegetables and raw milk products. Especially the most prominent pathogenic member Listeria monocytogenes can possibly cause the serious infectious disease Listeriosis with variable clinical syndromes. Lactobacilli belong to a group of healthy bacteria (probiotics) that produce the metabolic end product lactic acid and these bacteria commonly occur in nature but also in the human gastrointestinal tract. Lactobacilli are used for the production of milk products and curing of vegetables, fish, meat or other sausage products. Residential livestock like poultry or cattle can possibly be a reservoir for thermophilic Campylobacter species without any symptoms of illness. Therefore foodstuffs of animal origin (poultry, raw milk fish and seafood) are potentially contaminated. A contamination of these foodstuffs with Campylobacter can possibly cause diarrheal disease.
