What started as an ordinary lunch turned into a health crisis for New Mexico resident Trevor Keene. After biting into a McDonald’s Quarter Pounder in October, Keene found himself battling E. coli poisoning, joining the growing list of victims in a food safety scandal. On Thursday, he filed a class-action lawsuit against Taylor Fresh Foods, the Salinas, California-based farm that supplied the contaminated onions linked to the outbreak.
The Legal Claims
Keene’s lawsuit, filed in California federal court, accuses Taylor Fresh Foods of negligence in producing and distributing onions tainted with E. coli. According to the Centers for Disease Control and Prevention (CDC), the outbreak has resulted in over 100 infections, 34 hospitalizations, and one reported death.
The lawsuit alleges that Taylor Fresh Foods failed to disclose the risks associated with its onions, putting consumers like Keene in harm’s way. “Consumers expect the food they purchase to be safe for consumption and not contaminated by harmful bacteria,” Keene argued in his complaint. He seeks class certification, restitution, and an injunction to stop the company from selling its onion products until their safety can be guaranteed.
The Health Impact of E. Coli
E. coli is a bacteria commonly found in food, water, and the environment, according to the CDC. Infections can range from mild diarrhea to life-threatening conditions such as hemolytic uremic syndrome, a severe kidney failure. Elderly individuals, children, and those with weakened immune systems are particularly vulnerable.
Keene alleges that he experienced severe symptoms shortly after consuming the burger on October 21, a date that has now become pivotal in the investigation into the outbreak. The CDC later confirmed that slivered onions used in McDonald’s Quarter Pounders were the likely source of the contamination.
Negligence and Concealment Allegations
Keene’s lawsuit accuses Taylor Fresh Foods of withholding critical information about the contamination. “Defendant willfully and knowingly omitted material information regarding the quality and safety of the products,” the complaint states. Keene argues that Taylor Fresh Foods prioritized profits over consumer safety, creating a false sense of trust in its products.
The legal action seeks to hold the company accountable for its alleged negligence, claiming that Taylor Fresh Foods was unjustly enriched by continuing to sell tainted onions to unsuspecting consumers.
McDonald’s and CDC Response
As reports of illness mounted in late October, McDonald’s launched an internal investigation. By October 30, the CDC issued an update linking the outbreak to the onions provided by Taylor Fresh Foods. The farm subsequently began recalling its onion products, but not before significant damage had been done to consumers and the fast-food chain’s reputation.
Keene’s lawyer and representatives for Taylor Fresh Foods did not respond to requests for comment before publication.
The Path Ahead
The lawsuit adds pressure on Taylor Fresh Foods to prove its commitment to food safety and transparency. For McDonald’s, the scandal highlights the risks of supply chain vulnerabilities, even for a global giant. As the legal battle unfolds, the case serves as a stark reminder of the importance of stringent food safety standards and consumer trust.
