Were You Affected by McDonald's?

Answer a few quick questions to help us understand your situation.

Did you eat at or order food from McDonald's?

Receipts, app orders, card statements, or a dining companion can help document when and where you ate.

Did a doctor or lab confirm E. coli?

Medical records and lab results help document the illness, but an attorney can still review the facts if testing was not done.

Did you receive medical treatment?

Hospital visits, ER visits, or doctor appointments count.

Do you still have purchase, product, or exposure records?

Choose the closest answer. Missing a receipt does not automatically prevent an attorney from reviewing the claim.
