If you got your chickens or ducks in the last six months, stop and read this. The CDC is currently investigating eight simultaneous multistate Salmonella outbreaks tied to backyard poultry contact, and as of June 8, 2026, that means 513 people sick across 43 states and a U.S. territory, 134 hospitalizations, and one death in Washington state. What makes this different from the usual spring poultry outbreak story is the drug resistance angle. Some of the strains circulating right now don’t respond to first-line antibiotics, which changes the risk calculus for anyone who keeps birds and has young kids or immunocompromised people in the house.

I’ll be honest: I’ve been keeping chickens for a decade and I’ve rolled my eyes at the CDC’s annual “wash your hands after touching your chickens” messaging. It felt like the same pamphlet every year. But this situation is genuinely different, and I think a lot of backyard keepers are underestimating it.

Whole-genome sequencing on the Salmonella Saintpaul samples confirmed that all of them carry predicted resistance to fosfomycin. Eight samples also showed resistance to chloramphenicol, streptomycin, sulfisoxazole, and tetracycline simultaneously. Those aren’t obscure antibiotics. Streptomycin and tetracycline are workhorses of bacterial infection treatment, and multi-drug resistance in a strain spreading this widely is the kind of thing that makes infectious disease doctors nervous. When a Salmonella infection gets serious enough to require hospitalization, the treatment options for a resistant strain are narrower and more complicated.

What surprised me was how quickly this escalated compared to last year. The 2025 backyard poultry Salmonella outbreak ended with 559 people sick across 48 states, 125 hospitalizations, and two deaths. We’re already at 513 cases this year and it’s only early June. The trend line is going in the wrong direction.

Here’s a detail that I think every backyard keeper needs to sit with: 84% of poultry-owning case-patients got their birds since January 1, 2026, mostly from agricultural retail stores, and the outbreak strains have been traced back to seven specific hatcheries. That’s not a small, isolated problem. That’s contamination baked in at the source, moving through the retail supply chain and landing in backyards across the country.

This is why the “just keep your coop clean” advice only goes so far. You can run the most sanitary operation on your block and still bring Salmonella Saintpaul home in a box of day-old chicks from your local feed store. The CDC’s investigation update from June 8 confirms the hatchery connection is real and ongoing, which means birds being sold right now, during peak spring chick season, are potentially part of this.

If you bought birds this year, I’d contact the retailer and ask which hatchery supplied them. It’s an uncomfortable conversation but it’s worth having.

The Duck Problem No One Is Talking About

Most backyard poultry coverage focuses on chickens. This outbreak is forcing a harder look at ducks. The largest single outbreak in the current investigation involves an unusually high number of people who reported contact with ducks specifically, not just chickens.

Duck keepers tend to be a self-selected group who’ve done their research and feel confident they understand their birds. But ducks carry Salmonella just as readily as chickens do, and their water habits make contamination spread differently. Ducks splash, they foul their water almost immediately, and they track wet, contaminated substrate around in ways that chickens don’t. If you’re keeping a mixed flock or a duck-only setup, the hygiene protocols that work fine for chickens need to be tightened up. That water bowl your duck is bathing in is also contaminating everything it touches.

The Medscape coverage from April 30, 2026 flagged the duck connection early in the investigation, and it’s been underreported in the mainstream backyard chicken community since then.

Children Under Five Should Not Be Handling These Birds Right Now

The CDC is being unusually direct about this, and I think they’re right. Over a quarter of all case-patients in the current outbreak are children under five years old. The agency’s explicit recommendation is that children under five should not handle chicks, ducklings, or backyard poultry at all.

I know how this lands. The whole appeal of backyard chickens for a lot of families is exactly this: kids collecting eggs, holding fluffy chicks, learning where food comes from. I get it. But toddlers and babies are in the highest-risk category for serious Salmonella complications including bloodstream infections, and with drug-resistant strains in the mix, the consequences of a severe case are harder to manage. This isn’t a forever restriction. It’s a right-now restriction while eight concurrent outbreaks are active and the source hatcheries haven’t been cleared.

If you have young kids, keep them out of the coop and away from the birds until the CDC closes out these investigations. That’s just the honest call.

What You Can Actually Do

Clean hands are still the foundation, but the specifics matter. Dedicated footwear for the coop, worn only in the coop, keeps contaminated material from walking into your house. Hand washing immediately after any bird contact, using soap and water rather than hand sanitizer alone, is non-negotiable right now. Don’t let birds into the house. Don’t let coop clothing sit in the laundry room where kids play.

If you’re in the market for new birds and haven’t bought yet, I’d wait. Not forever, just until the CDC narrows down which hatcheries are involved and the supply chain picture is clearer. The Reader’s Digest coverage from May 2026 ran with a headline that felt sensational when I first saw it, but honestly the underlying reporting on the hatchery sourcing issue was solid.

If you already have birds from this spring, monitor them and yourself. Salmonella in healthy adult carriers doesn’t always show obvious symptoms in the birds. You won’t necessarily know your flock is carrying it.

This is a situation that deserves to be taken seriously without descending into panic. Backyard flocks are worth keeping. They’re also worth keeping carefully, and right now “carefully” means paying attention to an outbreak investigation that’s still very much open.
