Yesterday — June 14, 2026 — was the sell-by date printed on the batch of soft cheese that New York State investigators identified as contaminated with the exact Listeria monocytogenes strain that has killed one person and hospitalized eight others across three states. That fact — the temporal collision between the outbreak investigation's latest confirmation and the expiration of the contaminated product — makes this story more urgent than it was even 24 hours ago.
The FDA's June 2026 outbreak investigation page documents that the New York State Department of Agriculture and Markets collected a sample from an unopened 18-pound plastic container of Clover Hill Dairy Requeson Cheese with a sell-by date of 6/14/26 and batch number 2AA051526. Whole-genome sequencing confirmed that the Listeria strain found in that container is the outbreak strain — the same genetic fingerprint as the bacteria in the stool samples of the nine confirmed patients, including the person who died.
