Unpasteurized milk poses serious risks due to the risk of contamination with pathogenic flora. Contamination can occur at any time - from the source of milk, during transportation, storage, processing, etc.

In cow farms, E. coli and Salmonela and other bacteria are regularly found in fresh milk. At a particularly low level is the sanitary control of private producers, who allow themselves to sell milk without the necessary processing, analysis and proper storage.

Veterinarians specify that even if raw milk is tested for contamination, the lack of such does not provide 100% certainty that there is no contamination and the danger of consuming such an unpasteurized product cannot be ruled out.
