UNITED NEWS INTERNATIONAL (UNI) — One of the biggest egg producers in the United States has voluntarily recalled nearly 207 million eggs due to salmonella concerns.

Indiana-based Rose Acre Farms says it issued the recall out of a “abundance of caution.”

As of April 16, U.S. health officials say 23 people in nine states have fallen ill.

The Food and Drug Administration says the outbreak, which stretches from Florida to Colorado, has been traced back to a Rose Acre Farms facility in Hyde County, North Carolina.

Affected eggs were sold under a variety of brand names, including Food Lion’s store brand and Walmart’s Great Value brand.

If you think your eggs might be at risk, look for lot codes 011 through 102. They came from plant number P-1065.

Salmonella is associated with abdominal cramps, fever and diarrhea. Symptoms usually appear within three days of infection, and most healthy people will recover within a week.
