The Food and Drug Administration upgraded a recall of tomatoes in several states to its most severe, Class I, due to the risk of a potentially deadly salmonella contamination.
A Class I recall is defined by the FDA as “a situation in which there is a reasonable probability that the use of, or exposure to, a violative product will cause serious adverse health consequences or death.”
No illnesses have been reported to the FDA, according to its earlier notice.
“Consumers who have purchased these products are urged to not consume the products and return them to the place of purchase for a full refund or they may discard the product,” the FDA notice said.
Salmonella is a type of bacteria that can cause a number of symptoms, including diarrhea, nausea, vomiting, fever, stomach cramps, and dehydration, U.S. health authorities say. Most people recover within a week without any treatment, but some individuals can face more severe symptoms, including older people, young children, and those with weak immune systems.
According to the Centers for Disease Control and Prevention, in rare cases, salmonella can infect the blood, joints, nervous system, the brain or spinal fluid, and the urinary tract. Such complications can lead to death or hospitalization.
Symptoms generally start six hours to six days after swallowing the bacteria, while most people recover without treatment between four and seven days, according to health officials.
Several companies have issued recalls for whole cucumbers and cucumbers used in a range of sandwiches, salsas, and other foods linked to the outbreak. Target recalled dozens of products, including whole cucumbers, salads, and vegetable rolls.
