Remarks With the PT-scheme mayonnaise we offer a high quality assurance program for the most popular sauces and basic ingredients for many further foodstuff throughout the world. The requested parameters are the most important value-determining attributes like the egg content in mayonnaise as well as technologically relevant parameters like preservatives. Representatives of the family Enterobacteriaceae can occur in the intestine of humans and animals but also in raw foodstuffs. In heated products there should be no Enterobacteriaceae. Therefore Enterobacteriaceae serve as hygienic parameter for the production process of a lot of foodstuffs like milk products or meat products and others. This PT scheme was developed and established because some pathogenic species can additionally cause diarrheal disease. 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.
