The McDonald’s E. coli lawsuit arises from a 2024 multi-state outbreak of E. coli O157:H7 infections linked to contaminated slivered onions used in McDonald’s Quarter Pounder hamburgers. The outbreak affected at least 104 individuals across 14 states, leading to 34 hospitalizations and one death. Plaintiffs in the lawsuit allege McDonald’s and its onion supplier, Taylor Farms, failed to ensure the safety of their food products, resulting in severe health consequences.
Background of the McDonald’s E. coli Lawsuit
The outbreak was first identified in October 2024 following reports of gastrointestinal illness among people who had consumed McDonald’s Quarter Pounder sandwiches. Federal and state agencies, including the FDA and CDC, launched investigations which traced the probable source to contaminated onions supplied by Taylor Farms.
McDonald’s responded by temporarily removing Quarter Pounder items containing slivered onions from affected markets and implemented measures to address the contamination. Taylor Farms issued a voluntary recall of potentially affected onions. Despite these efforts, numerous individuals were sickened, many requiring hospitalization for severe symptoms including bloody stool and hemolytic uremic syndrome (HUS), a serious kidney complication.
Parties and Legal Context
The lawsuit includes McDonald’s Corporation and Taylor Farms as primary defendants. Plaintiffs are consumers who suffered illness after eating contaminated McDonald’s products. The legal actions seek to hold these companies accountable for negligence, product liability, and failure to provide safe food products. Several individual and class-action lawsuits have been filed in various jurisdictions across the U.S.
Details of Allegations
Plaintiffs allege that:
- McDonald’s and Taylor Farms negligently sourced, handled, and served contaminated onions causing widespread illness.
- Companies failed to exercise reasonable care in food safety protocols and supply chain management.
- Consumers suffered physical injuries including severe gastrointestinal illness, hospitalizations, and one fatality.
- McDonald’s continued to serve contaminated products despite awareness of risks.
Legal Claims and Relevant Laws

These claims fall under consumer protection laws and food safety regulations enforced by agencies such as the FDA.

Victims faced serious health challenges, financial burdens from medical treatment, and emotional distress. The outbreak also caused operational disruptions and temporary menu changes in multiple McDonald’s locations.
Current Status and Developments
As of late 2024 and early 2025, multiple lawsuits have been filed and some settlements reached, though many remain pending. Investigations by health agencies continue to inform ongoing litigation. McDonald’s has cooperated with authorities and implemented enhanced food safety measures.
Consumer Advice
Consumers who ate McDonald’s Quarter Pounder products in affected regions during the outbreak period and subsequently experienced symptoms consistent with E. coli infection should seek immediate medical care. Retaining purchase receipts and medical documentation is advisable to support potential legal claims.
Consumers should remain alert to food recalls and advisories and report adverse health effects promptly.
Conclusion: Significance and Outlook
The McDonald’s E. coli lawsuit highlights the vital importance of food safety and corporate responsibility in mass-market food production. It also reflects the legal recourse available to consumers harmed by contaminated products. The resolution of these cases will reinforce industry standards and regulatory oversight to better prevent future outbreaks and protect public health.
