Category Archives: Food Toxin

The different categories are:

PN = pasteurized milk product produced in Norway.

P EU = pasteurized milk product produced outside Norway.

UN = unpasteurized milk product produced in Norway.

U EU = unpasteurized milk product produced outside Norway.
The various disease-causing infectious agents we analyzed for:

Listeria monocytogenes (pathogen): PN, P EU, UN, U EU, number 189 pcs.

Shigatoxin-producing Escherichia coli (STEC) (pathogen): UN, U EU, number 96 pcs.

E. coli (hygiene parameter): PN, UN, U EU, 169 st.

S. aureus (hygiene parameter): UN, number 71 st.

Toxins (enterotoxin) from S. aureus (pathogen): UN, U EU, number 96 pcs.

Salmonella (pathogen): U EU, number 25 st.

Shigatoxin-producing Escherichia coli (STEC):
One finding in French red cow cheese of cow’s milk ( E. coli O-, stx2 and eae ). A total of 25 unpasteurized milk products produced outside Norway were examined. No findings in 71 unpasteurized milk products from Norway.

Escherichia coli (hygiene parameter):
In 73 pasteurized milk products from Norway, there was a detection and this was above the lower limit value (100 kde / g) but below the upper limit value (1,000 kde / g). No E. coli was detected above the detection limit of 10 colony forming units / g sample (kde / g) in the other samples.

In 61 of the 71 unpasteurized milk products produced in Norway, E. coli was not detected above the detection limit of 10 colony-forming units / g sample (kde / g). 3 st. (4.2%) was above 100 kde / g.

In unpasteurized dairy products from the EU (25), 5 (20%) of the products had more than 100 kde / g E. coli. There is no microbiological criterion for E. coli in the regulations for unpasteurized cheeses.

Staphylococcus aureus:
Of 71 samples, none exceeded the regulatory limit of 10,000 kde / g.

Of the 96 unpasteurized dairy products examined, the enterotoxins AE Toxins (enterotoxins), which some S. aureus can produce , were not detected .

Salmonella was not detected in the 25 samples of unpasteurized milk products produced outside Norway.
