Salmonella Outbreak Prompts Egg Recall by Wisconsin Farm

A salmonella outbreak that has sickened dozens of people in nine states prompted a recall of certain brands of eggs on Friday after officials said they traced the source of the infections to a farm in Wisconsin.

State health officials said that 42 of the 65 people infected were in Wisconsin. Many people reported eating eggs at restaurants in the state before they got sick.

Officials were able to trace the source of the eggs to Milo’s Poultry Farms of Bonduel, Wis., where they identified the outbreak strain in a packing facility and a hens egg-laying house, the U.S. Centers for Disease Control and Prevention said.

All carton sizes and egg types produced at the farm, which either bear the label “Milo’s Poultry Farms” or “Tony’s Fresh Market,” were recalled by the farm, the U.S. Food and Drug Administration said.

The eggs were distributed to retail stores and food service suppliers in Illinois, Michigan and Wisconsin, the F.D.A. said. The recall includes all expiration dates. The exact number of eggs recalled was not immediately available.

No deaths have been reported in the outbreak, but 24 people were hospitalized. The first case was reported in late May, but most infections were reported in July and August, according to the C.D.C.

The reported number of people infected is likely an undercount because it usually takes weeks to determine if an infection is part of an outbreak and because some people may recover without testing for the bacteria, the C.D.C. said.

Aside from Wisconsin, infections were reported in California, Colorado, Illinois, Iowa, Michigan, Minnesota, Utah and Virginia. Illinois reported the second-highest number of infections with 11, followed by Minnesota, which reported three.

The symptoms of the bacterial infection include diarrhea, fever and abdominal pain and usually begin within three days of ingesting the contaminated food, the F.D.A. said.

Symptoms usually clear up within a week, but people with weakened immune systems, including young children and older adults, are more susceptible to severe, and sometimes fatal, infections, the F.D.A. said.

The egg recall came after a deadly summer outbreak of listeria that prompted the recall of seven million pounds of Boar’s Head deli meat products.

That outbreak has resulted in nine deaths and dozens of hospitalizations and the temporary shutdown of a Boar’s Head plant in Virginia, where inspectors had found black mold, water dripping over meat and dead flies.
