Assessment

Medium-High confidence — 4/4 signals corroborated across 4 independent sources

A multi-state cyclosporiasis outbreak is ongoing in the US, with the FDA confirming a recall of Mexican-grown lettuce as a source. Health Secretary RFK Jr. claims the outbreak is controlled, but this contradicts the FDA's recent recall reversal and expert projections of rising infection rates. The specific source of contamination for the broader outbreak remains under investigation.

Why it matters — The outbreak poses a public health risk and highlights potential vulnerabilities in the food supply chain, particularly concerning imported produce.
