BREAKING NEWS: Backyard poultry Salmonella outbreak turns deadly

The number of confirmed Salmonella infections linked to contact with backyard poultry has increased almost 15-fold, from seven cases in 6 states as of May 5, 2025 to 104 cases in 35 states as of May 30th.

One person has died; twenty-five have been hospitalized.

The CDC has added a second outbreak strain to its investigation. The agency reports that cases linked to backyard poultry include infections with Salmonella Mbandaka and Salmonella Enteritidis.

Victims range in age from less than one year to 85 years, with a median age of 18 years. Nearly one third of the victims (32%) are less than five years old.

If history is any indicator, we could easily see another 10-fold increase in the confirmed case count. During the decade spanning 2015-2024, contact with backyard poultry accounted for more than 9300 confirmed Salmonella infections, 1,999 hospitalizations and 12 deaths.

The annual backyard poultry Salmonella outbreak has begun

Having bid farewell to Easter just a couple of weeks ago, it’s now time to welcome the annual Salmonella outbreak that is the inevitable outcome of those cute chicks and ducklings.

The US Centers for Disease Control and Prevention (CDC), aided by public health departments in several states, has opened an investigation into seven cases of Salmonella Mbandaka infections. The cases are spread across six states.

The victims range in age from less than one year old to 55 years old. Forty-three percent are less than five years old.

The outbreak strain is the same one that was linked to two hatcheries in past outbreaks, including one which is also linked to the poultry shipping material sample in the current outbreak.

Investigators in Ohio collected samples from the inside of boxes used to ship poultry from hatcheries to retail stores, including the box liner and bedding. WGS showed that the Salmonella Mbandaka found in these samples was the same strain as the one found in sick people.

According to the CDC, the true number of cases may be much larger than the cases reported so far. Victims who do not seek medical attention (whether due to mild symptoms or to the cost of health care) do not get tested for Salmonella. Additionally, it can take 3-4 weeks for a diagnosed case to be reported to the CDC.

In the last decade, Salmonella outbreaks linked to backyard poultry have produced more than 9,300 known victims, causing 1,999 hospitalizations and 12 deaths.

  • 2024: 470 cases; 125 hospitalizations; 1 death
  • 2023: 1,072 cases; 247 hospitalizations; 0 deaths
  • 2022: 1,230 cases; 225 hospitalizations; 2 deaths
  • 2021: 1,135 cases; 273 hospitalizations; 2 deaths
  • 2020: 1,722 cases; 333 hospitalizations; 1 death
  • 2019: 1134 cases; 219 hospitalizations; 2 deaths
  • 2018: 334 cases; 56 hospitalizations; 0 deaths
  • 2017: 1120 cases; 249 hospitalizations; 1 death
  • 2016: 895 cases; 209 hospitalizations; 3 deaths
  • 2015: 252 cases; 63 hospitalizations; 0 deaths

There is no reason to expect that this year’s outbreak will be any different.
