Till date, as many as 900 illnesses have been reported, including more than 180 hospitalizations, though no deaths have been reported as a result of consuming the products.

Consumption of food contaminated with salmonella can cause salmonellosis, one of the most common bacterial foodborne illnesses. The most common symptoms of salmonellosis are diarrhea, abdominal cramps, and fever within 12 to 72 hours after eating the contaminated product. However, most people recover without treatment.

In some people, diarrhea may be so severe that the patient needs to be hospitalized. Older adults, infants, and persons with weakened immune systems are more likely to develop a severe illness.
