The enterocolitica bacteria constitute one of the most common intestinal pathogens. They are transmitted to humans through food and water. Milk is one of the major sources of transmission of infection to humans. Complications caused by infection with these bacteria are increasing across the globe. Therefore, the likelihood of social exposure to a health hazard is not ruled out. The relationship between acute diarrhea in children and enterocolitica has been determined. Six enterocolitica serotypes 0:3 have been isolated from diarrheal samples of children under 14 at a Children’s Medical Center in Tehran. Enterocolitica are resistant to antibiotics but sensitive to aminoglycosides. The group with the highest exposure to hazard is adolescents and children aged under 5. In adults, it appears in the form of pseudo-appendicitis syndrome. Hundreds of people may undergo appendectomy by surgeons due to enterocolitica infection. The psychrophilic nature of the bacteria may pose a problem in the differential diagnosis of diseases, including brucellosis, in the cold regions of Iran. Serotypes 0:9, 0:8 and 0:3 appear in humans with three properties: ability to invade and adhere to the host’s epithelial cells; ability to cause ulcers in the guinea pig’s cornea; and production of pathogenic heat-resistant enterotoxin. The highest rate of infection and prevalence has been reported in Western Europe and Iran’s Shahr-e Kord. The frequency of infection with enterocolitica in 300 samples of meat purchased from supermarkets in Shahr-e Kord was reported at 14% in 22 samples: beef and lamb (4%) and livestock (34%). The frequency of infection with enterocolitica serotype 0:3 in chicken samples was reported at 21.66% in 3,300 samples and 15.38% in 10 samples. The frequency of infection in 150 samples of raw milk in Ahvaz, in 36 samples (24%). In 2015, the prevalence of enterocolitica in the raw milk of sheep and goat was reported at 2.4%. This study aims A quick review of enterocolitica induced health hazard on global scale
