coli was detected in Haidilao chopsticks. What harm do they do

Recently, a batch of chopsticks used in a store of Haidilao Hot Pot was detected with coliform bacteria. Haidilao explained that it was caused by improper storage of chopsticks, and the store was also open normally.

Escherichia coli is a parasitic bacteria in the intestines of humans and animals. Whether it causes disease or not depends on the type of Escherichia coli and personal physique.


Clinically, the Escherichia coli that can cause human diarrhea is divided into five types: enteropathogenic Escherichia coli; enterotoxigenic Escherichia coli; enteroinvasive Escherichia coli; enterohemorrhagic Escherichia coli and enteroadhesive Escherichia coli.

Among them, O157: H7 Escherichia coli can cause hemorrhagic enteritis. The incubation period of general pathogen infection is 1-14 days. In mild cases, there may be no symptoms and signs, or only mild diarrhea. Some patients have fever or upper feeling symptoms, and the symptoms usually subside within 1-3 days. Most patients recover within 5-10 days. However, the elderly, children, and the infirm may be more serious, causing hemorrhagic enteritis, and complications such as hemolytic uremic syndrome appear in the course of 1-2 weeks.

Most of the clinical symptoms of E. coli infection are diarrhea and gastrointestinal infections, which can cause human enteritis and even severe sepsis.

In my country's food supervision, coliforms are one of the commonly used indicator bacteria for food contamination at home and abroad. According to the report of the Hangzhou Municipal Market Supervision Bureau, according to regulations, the standard for E. coli in food testing is "not to be detected."


The main cause of excessive coliforms in catering tableware is secondary pollution, such as the tableware is not cleaned and disinfected regularly, or the tableware does not reach the specified time and temperature during dry heat disinfection. Operators do not wash their hands thoroughly after going to the bathroom, and their personal hygiene is not up to standard, which directly affects the hygiene of the final product.

"The detection of E. coli on chopsticks is a manifestation of non-standard disinfection." Gastroenterology experts pointed out that for the human body, in order to prevent diseases caused by E. coli, it is necessary to develop good living habits. Before eating, the food should be fully heated, the water should be boiled before drinking, the hands should be washed before and after the meal, and the raw vegetables and fruits should be washed before eating.
