E. coli Outbreak Linked to Raw Cheese Sickens 13, Injures Three

Health officials are warning of a multi-state outbreak of a deadly bacteria linked to raw cheese, which has sickened 13 people and left three with life-threatening kidney injuries. The Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) are investigating the outbreak caused by the E. coli strain O26:H11.

Illnesses and Complications

This strain of E. coli produces Shiga toxins that can harm the gut lining, leading to severe stomach cramps, watery or bloody diarrhea, fever, and vomiting. Of the 13 individuals who have fallen ill, eight have required hospitalization. Three cases have developed hemolytic uremic syndrome (HUS), a severe condition that can result in kidney failure.

The illnesses were reported in nine states: California, Colorado, Georgia, Kentucky, Michigan, Nevada, Oregon, Tennessee, and Utah. The ages of those affected range from one to 58 years, with an average age of five. Children five years old and younger represent over half of the cases.

Potential Source and Recall

Federal health agencies are investigating Sierra Nevada Graziers grass-fed raw milk cheese as the potential source of the outbreak. Sierra Nevada Cheese Company, LLC has initiated a voluntary recall of its medium cheddar, sharp cheddar, Monterey jack, and jalapeno jack products after being informed of the E. coli outbreak. It remains unclear which specific products were contaminated.

The recalled products were made with raw, or unpasteurized, milk. Pasteurization, a process that uses heat to kill harmful bacteria, is crucial for making dairy products safe for consumption. Raw milk products are inherently more prone to carrying pathogens like E. coli.

Recalled products were sold in 8oz or 16oz packages in unspecified retail stores, and also to food service customers or wholesalers in 5lbs loaves or large blocks. Consumers who purchased the recalled cheese are advised to return it to the place of purchase for a refund.

Investigation and Timeline

State and local health officials are interviewing those who have fallen ill to determine the source of their sickness. According to CDC data, all nine individuals interviewed reported consuming Sierra Nevada Graziers grass-fed raw milk cheese prior to becoming sick. Illnesses were reported to the CDC between July 7 and August 26.

The CDC cautions that the actual number of infected individuals is likely higher, as many people recover without being tested for E. coli. It can take three to four weeks to confirm if a sick person is part of an outbreak, meaning recent illnesses may not yet be accounted for.

The FDA stated that its investigation is ongoing to pinpoint the source of contamination and identify any additional affected products. E. coli bacteria can survive freezing temperatures and reactivate in warmer environments. Symptoms typically appear two to eight days after exposure, with most patients recovering within a week. However, severe cases can lead to HUS, particularly in young children, the elderly, and individuals with compromised immune systems. Symptoms of HUS can include easy bruising, decreased urine output, and a pale appearance, potentially requiring a kidney transplant in critical situations.

The CDC advises individuals experiencing severe diarrhea, fever above 102°F (39°C), bloody diarrhea, persistent vomiting, or signs of dehydration to seek immediate medical care. The agency also recommends against consuming raw dairy products and advises thorough cleaning of any items or surfaces that may have come into contact with recalled products.
