Some toxins are so deadly that, in susceptible individuals, they can cause the kidneys and heart to fail. The bacteria are found in the intestines of cattle. They become increasingly antibiotic resistant because antibiotics are liberally used in the cattle industry.Ultimately, these bacteria can make their way into our food and have the potential to cause serious illness.
