Anmerkungen Lactose free products need to have a lactose content < 0.1% lactose. To verify that one can determine lactose contents < 0.1 % is the scope of this proficiency testing. This proficiency testing scheme covers the value-assessing parameters in raw cream which are of great importance for dairy plants, veterinary and customs inspection service as well as for all food testing laboratories which cover the chemical raw cream testing in the scope of its test program. The microorganism E.coli is part of the intestinal microflora of humans and warm-blooded animals. Furthermore E.coli is used as an indicator organism for faecal pollution and hygienic parameter a lot of different foodstuff like milk products or meat products. Therefore we developed and established the present proficiency testing scheme. 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. 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. Aerobic spore-forming bacteria usually occur in soil but also in meat, milk or herbal foodstuffs and can lead to taste changes and spoilage. These bacteria are able to survive the pasteurisation step using their heat-stable spore-form. Some of their pathogen representatives produce enterotoxins causing regurgitation or diarrhoea.
