The Yakima Health District in Yakima, Washington has launched an investigation into three confirmed cases of Shiga toxin-producing E. coli infections linked to a local grocery store. All three of those affected reported consuming meat, produce, or prepared foods purchased from Mercado Los Amigos, located at 1409 Fruitvale Boulevard in Yakima, Washington.
In response, Mercado Los Amigos voluntarily closed its doors on September 18, 2025. The store is currently working with health district officials to assess the situation and implement measures to ensure food safety standards are met before reopening.
Health authorities are advising anyone who purchased or consumed food items from the market between September 10 and September 18, 2025, to monitor their health closely. Customers should seek medical attention if they develop symptoms including severe abdominal cramping, bloody diarrhea, or vomiting.
The majority of people infected with this strain of E. coli typically recover within five to ten days without requiring medical treatment. However, certain populations face elevated risks for severe complications. Children under five years old, adults over 65, and individuals with compromised immune systems may experience more serious illness, potentially including kidney failure.
E. coli bacteria are naturally present in various environments, including food, water, and soil. While most strains pose no threat to human health, Shiga toxin-producing E. coli can cause significant illness. The bacteria commonly spread through consumption of undercooked or raw beef, particularly ground beef products. Raw produce contaminated with animal waste also serves as a transmission source.
Cross-contamination in food preparation areas represents another pathway for infection, as does person-to-person transmission when proper hand hygiene is not maintained after bathroom use.
Health officials recommend several preventive measures to reduce infection risk. Thorough cooking of meat products, especially ground beef, eliminates harmful bacteria. Fresh fruits and vegetables should be washed carefully before consumption, and cooking these items provides additional protection.
Regular handwashing with soap and water remains a fundamental prevention strategy. Food handlers should maintain strict separation between raw meat products and ready-to-eat foods during storage and preparation.
The health district’s disease control director stressed the importance of following basic food safety practices and remaining alert to symptoms. Individuals experiencing gastrointestinal symptoms are urged to contact their healthcare providers promptly.
The investigation remains active, with health officials continuing to trace the source of contamination and assess the scope of potential exposure. Additional information will be released as the investigation progresses and more details become available.
Nationwide E. coli law firm Ron Simon & Associates says that this incident highlights the ongoing importance of food safety protocols in retail food businesses and the need for consumers to remain educated about proper food handling practices in their homes.
