What happened

A California raw milk dairy that was previously linked to a fatal outbreak of bird flu in cats has now been linked to an E coli outbreak involving cheddar cheese, affecting nine people in three states.

Why it matters

The US Food and Drug Administration (FDA) said in an alert that more than half of the people sickened so far are children under age five.

Common ground

Three people have been hospitalized after contracting a dangerous strain of E coli – O157:H7 – with one developing hemolytic uremic syndrome, a condition that can lead to kidney failure.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.

Claim 13: “In December 2024, Raw Farm was identified as the source of H5N1 bird flu in three Los Angeles-area cats that had consumed raw milk. Two died, and fears were raised that that cats, like pigs, had cellular receptors which allow them to act as 'mixing vessels for reassortment of avian and mammalian influenza viruses'.”
INSUFFICIENT EVIDENCE
No evidence found to support claims about H5N1 in cats linked to Raw Farm in 2024.
