Escherichia coli is mainly transmitted through contaminated food, and there is no evidence that human contact leads to widespread transmission. Escherichia coli is mainly transmitted to humans by eating contaminated food, such as raw or undercooked minced meat products and raw milk.
Water contaminated by feces and other foods and cross-contamination during food preparation (with beef and other meat products, contaminated surfaces and kitchen utensils) can also lead to infection.
The foods that cause the E.coli epidemic include undercooked hamburgers, air-dried sausages, freshly squeezed cider that is not completely sterilized, yogurt and cheese made from raw milk. People who have come into contact with animals (especially livestock) and people or things with harmful bacteria may be infected if they don't wash their hands carefully.

Harm of Escherichia coli to human body;
Coliform group is not a taxonomic name of bacteriology, but a term in the field of sanitary bacteria. It does not represent a certain bacterium or a certain genus, but refers to a group of bacteria with certain characteristics related to fecal pollution. These bacteria are not completely consistent in biochemistry and serology. It is generally believed that the bacteria of this flora can include Escherichia coli, Citrobacter, Klebsiella aerogenes and Enterobacter cloacae.
Coliform group is put forward as an indicator of fecal contamination, and the detection of coliform group mainly indicates whether there is fecal contamination in food. The number of coliforms indicates the degree of fecal pollution and also reflects the harm to human health. Feces are human intestinal excreta.
There are feces of healthy people, feces of intestinal patients or carriers, so in addition to normal bacteria, there are some intestinal pathogens (such as Salmonella and Shigella). ) in feces, so there is fecal pollution in food.
It can be inferred that the food may be contaminated by intestinal pathogenic bacteria, and the threat of food poisoning and epidemic disease lurks, so it must be regarded as a potential danger to human health.
