Federal health officials reported a salmonella outbreak affecting nearly 100 people across 17 states. The U.S. Food and Drug Administration stated that these illnesses occurred between November 21 and June 30.

Midwest Poultry Services is believed to be a primary source of the contamination. However, their recalled eggs do not account for all cases. The Indiana-based company had earlier recalled eggs from farms in Texas, distributed from June 6 to July 3. These eggs were sold under various brand names, with sell-by dates from July 20 to August 17.

Recalled eggs were distributed to major stores including Kroger in Texas and Louisiana, and Brookshire Grocery in Texas, Oklahoma, Arkansas, Louisiana, New Mexico, and Mississippi. Tests at Texas farms showed salmonella, with some strains matching those sickening consumers.

“Consumers should check their refrigerators for recalled eggs and discard them or return them to stores for a refund,” advise federal officials.

Symptoms of salmonella include diarrhea, fever, severe vomiting, dehydration, and stomach cramps. Most individuals recover in a week, but young children, older adults, and those with weakened immune systems may require hospitalization.
