The federal listeria investigation into soft cheese is holding at a single repackaging facility, and the plant — not the category — is the usable unit. The FDA and CDC report the outbreak of Listeria monocytogenes traced to requesón, a ricotta-style soft cheese manufactured by Clover Hill Dairy of Mechanicsville, Maryland, and repackaged for retail by La Ceiba Foods Latin Market Inc. [1] The count holds at 12 illnesses across four states, 10 hospitalizations, and one death [2].

As this paper reported Monday, a repackager is where bulk cheese is re-portioned and relabeled — which makes it the exact node where contamination enters and where the traceback terminates. La Ceiba took bulk product from Clover Hill and sold it under multiple Latin-market brand names, which is why a single source produced a long recall list. The service task follows from that: check whether a soft cheese came through the flagged repackaging chain and its July 10, 2026 expiration date, not avoid all soft cheese [1].

The investigation remains active. The FDA says additional products may be affected and testing continues; laboratory work has matched listeria in the cheese samples to the strain in the sick people [2]. But the trace has not moved off the plant, and no resolution has been declared. Filed alongside the California Dairies dry-milk-powder cascade the paper tracked in the Utz chip recall, this is one ingredient-mapping thread: the named facility is the operating fact, and the reader's job is a lot check, not a shelf purge.
