An outbreak of food poisoning has spread across the U and in at least two states, with several more people hospitalized.
Officials are trying to track down what happened.
The Centers for Disease Control and Prevention and the Food and Drug Administration have reported a total of 23 cases in Texas, New Mexico, Georgia, North Carolina and Tennessee.
The CDC is treating them as foodborne illnesses.
A state of emergency was declared in Texas on Saturday, after a person in a car was found dead in the desert.
It was not immediately clear if the man was among the 23 people hospitalized or dead.
Food poisoning is often caused by exposure to food contaminated with the pathogenic coronavirus.
People can be infected with food poisoning through direct contact with contaminated foods, such as from eating food or drinking from contaminated containers.
A person can become ill from eating contaminated food if the virus infects the stomach and intestines.
In the most severe cases, a person can contract the disease from the food they ate.
The virus is also found in fruits and vegetables, but rarely in meat.
The number of cases nationwide is at its lowest point in more than three years.
