McDonald’s class action alleges quarter pounder burgers contain E. coli

McDonald’s Quarter Pounder class action lawsuit overview:

• Who: A customer has filed a class action lawsuit against McDonald’s USA LLC.
• Why: The plaintiff claims McDonald’s failed to disclose E. coli contamination affecting its quarter pounder burgers
• Where: The class action lawsuit was filed in Illinois federal court.

A new nationwide class action lawsuit alleges that McDonald’s failed to disclose that its quarter-pounder burgers were contaminated with E. coli. 

Plaintiff Tammy Williams claims McDonald’s improperly, deceptively and misleadingly labeled and marketed its quarter-pounder burgers by choosing not to disclose alleged  E. coli contamination.

The class action lawsuit argues McDonald’s quarter-pounder burgers can cause mild to severe gastrointestinal illness, with the risk of serious infection particularly concerning for children under the age of 5 years, adults older than 65 and people with weakened immune systems.

Williams wants to represent a nationwide class and Nevada subclass of consumers who bought a McDonald’s quarter pounder burger during the applicable statute of limitations period.

McDonald’s quarter pounder burgers used slivered onions recalled for E. coli risk, class action says

Williams argues that McDonald’s quarter-pounder burgers contain slivered onions from Taylor Farms, which were recalled on Oct. 25, 2024, due to E. coli contamination.

“Plaintiff purchased and ingested Defendant’s Burgers that contained Escherichia coli (E. coli), including the Burgers that were subject to the recall,” the McDonald’s Quarter Pounder class action says.

Williams claims McDonald’s is guilty of negligence, unjust enrichment and of violating the Illinois Consumer Fraud and Deceptive Trade Practices Act. 

The plaintiff demands a jury trial and requests declaratory and injunctive relief and an award of actual, statutory, treble and punitive damages for herself and all class members.

Consumers filed a similar and separate lawsuit against McDonald’s after purchasing and eating food from the fast-food restaurant. A class action has also been filed against Taylor Fresh Foods for its role in the McDonald’s E.coli contamination.
