Evaluating the rate of contamination of raw milk with pathogenic biotypes of Yersinia enterocolitica in the North-East of Iran

Abstract

<jats:title>Abstract</jats:title> <jats:p>Objective: This study aimed to evaluate the contamination rate of raw milk to Y. enterocolitica and biotyping of isolated organisms. Results: The results showed 33% of raw milk samples were contaminated with Yersinia enterocolitica. 1A biotype was the predominant one (26%) but two pathogenic biotypes including 1B (6%) and 5 (1%) were also detected. Isolation of potentially pathogenic Y. enterocolitica from raw milk and consequently its presence in dairy products which are made from raw milk is a public health hazard.</jats:p>
