(NEXSTAR) – A recall issued last week has now expanded to include two brands of eggs that may be contaminated with salmonella. The two affected brands, according to the Food and Drug Administration, are Kenz Henz and Black Sheep Company, which can both be traced back to a Black Sheep Egg Company facility in Walnut Ridge, Arkansas. When FDA inspectors took samples from the facility, they found 40 samples were positive for seven different strains of salmonella. People who eat food contaminated with salmonella usually experience gastrointestinal issues like diarrhea and stomach cramps. They can also develop a fever. Young children, the elderly, and those with weakened immune systems may experience more severe symptoms and complications. The Black Sheep Company may have distributed contaminated eggs to companies in Arkansas and Missouri that have also repackaged and distributed them under different brands. Kenz Henz, for example, is based in Santa Fe, Texas, and sold its eggs at retailers around Houston. The FDA said it will continue to update the public if more brands are added to the recall. Recalled eggs may still be in people's fridges, as the expiration dates are recent or have not yet passed. While no illnesses have been reported in connection with the recall, the FDA still encourages people to check their homes for the eggs and either throw them out or return them to the store for a refund. The egg cartons affected by the recall so far are:
