SEATTLE, WA – King County Public Health is investigating six E. coli cases that appear to be linked to a food truck that visited farmers markets.

“Through a few initial interviews with ill people, we determined that everyone who became sick had something in common – they ate food prepared by, a local food vendor called Los Chilangos,” Public Health staff said in a statement.

The department required the food truck to stop selling food.

A 4-year-old girl is one of those affected, and her mother said her daughter became sick after eating at Los Chilangos around August 8.

The food truck visited the Issaquah and Sammamish farmers markets.

Deanna Buder said her 4-year-old daughter started experiencing pain and swelling in her abdomen, and stopped eating. Tuesday is her seventh day at Seattle Children’s Hospital.

Los Chilangos serves food at seven farmers markets in King and Snohomish counties, operates two food trucks, and also caters events. Los Chilangos uses Eastside Commercial Kitchen, where they share space and equipment with about a dozen other food businesses.

The kitchen was told to stop producing food, as were the food trucks that used it.
