This question will be resolved based on data from the CDC. As of October 22nd 2024, there are 49 confirmed cases linked to McDonald’s Quarter Pounders across 10 states. The total number of confirmed cases by December 31, 2024, will be determined by official CDC updates, public health reports, and press releases.

The question may be resolved sooner if CDC provides final cases before 12/31/24. If the outbreak extends beyond 12/31/24, the final case count on 12/31/24 will be used for resolution.
