CDC is investigating three concurrent salmonella outbreaks — Enteritidis, Mbandaka, and Saintpaul — linked to contact with backyard poultry, and as of May 4 the count is 184 sick across 31 states, 53 hospitalized, with one death in Washington. [1] More than a quarter of those sickened are children under five. [1]

The paper's May 19 brief argued the recall page often shows the consumer signal before the outbreak narrative arrives, but the outbreak narrative has now caught up to the ledger: since CDC's April 23 update, 150 new illnesses have been reported, and two new outbreak strains were added. [1]

Of 141 people interviewed, 78% reported contact with backyard chickens, ducks, or other poultry in the week before they got sick, and the largest of the three outbreaks has an unusually high number of patients reporting contact with Pekin ducks specifically. [1] CDC notes the true case count is likely much higher because most people recover at home and are never tested. [1]

The instruction is small and unglamorous — wash hands thoroughly after handling birds or anything in their environment, and keep poultry out of kitchens — but the under-five fraction is what makes it urgent. [1] Healthy adults usually clear salmonella in four to seven days. Children under five, adults over 65, and the immunocompromised are at higher risk for serious complications, which is why hospitalization runs at 34% in this outbreak.

A backyard coop is not by itself a public-health hazard. A backyard coop with a toddler nearby and no hand-washing station is what the case map describes.
