Mass poisoning at McDonald's: experts found the source of the infection.

In the United States, outbreaks of intestinal infection have occurred among people who visited McDonald's. According to the investigation, the cause of the infection was the presence of E.coli bacteria in the onions used for hamburgers. This was reported by representatives of the Centers for Disease Control and Prevention (CDC) in the USA.

The onion supplier for the regions with the infection outbreaks was confirmed to be Taylor Farms. The U.S. Food and Drug Administration began an inspection at the plant in Colorado, where 29 cases were recorded. The onion producer in Washington state is also being checked.

The E.coli that caused the outbreak at McDonald's can cause serious illnesses, especially among the elderly and those with weakened immune systems. Symptoms appear a few days after eating contaminated food.

The infection outbreak has been recorded in Colorado, Kansas, Utah, Wyoming, Iowa, Missouri, Montana, Nebraska, New Mexico, Oregon, Wisconsin, Washington, and Michigan.

To put it mildly, the more such cases appear in the news, the harder it will be for McDonald's to reset, believes Jim Sanderson, an analyst at Northcoast Research.

The company's management believes that this outbreak will not affect sales. The CEO apologized to customers and assured them that McDonald's products are safe.

Note that the first cases of E.coli infection at McDonald's were identified on October 22. Since then, infection outbreaks have been recorded in 13 states. The number of infected currently stands at 90 people, with one fatality.
