Salmonella is an organism that can cause serious and sometimes fatal infections in young children, frail, or elderly people, along with people with weakened immune systems.

Healthy people infected with Salmonella often experience fever, diarrhea, nausea, vomiting, and abdominal pain. In rare cases, Salmonella can get into the bloodstream and cause more serious infections.

If you purchased impacted eggs, you can return it to the place of purchase for a full refund.
