US scientists have identified an unexpected danger of milk
Experts from the US Centers for Disease Control and Prevention found that consumption of fresh milk is associated with the spread of antibiotic-resistant infections. This is reported by the ArsTechnica.
In 2016, the state of Colorado recorded 12 cases of infection with the bacterium Campylobacter jejuni, which affects the gastrointestinal tract with the formation of secondary foci in other organs, abscesses and necrosis.
Although the sale of fresh milk in the state is illegal, some farms have bypassed the ban. The epidemic covered 171 farms, but only 91 of them stopped distributing milk after a warning from the authorities.
Researchers note that the increase in the number of outbreaks of Campylobacter jejuni infection due to unpasteurized dairy products occurred in 2015. Given the epidemiological indicators since 1993, there has been a fourfold jump in morbidity. At the same time, the risk of contamination with bacteria due to consumption of raw milk is 150 times higher than that due to pasteurized milk.
Symptoms of Campylobacter jejuni include fever, intestinal cramps, vomiting and diarrhea, and microorganisms themselves can be found in water and food, including milk. In this case, the bacteria are resistant to three antibiotics: tetracycline, nalidixic acid and ciprofloxacin.
