Seafood firm Seven Seas International USA recalled several of its smoked salmon products due to concerns that they might be contaminated with infectious bacteria.
Listeria monocytogenes is usually transmitted to humans when food is harvested, packaged, and stored in environments where bacteria are present.
Symptoms of the infection can range from mild ones like fever, vomiting, nausea, and muscle aches to more severe convulsions and loss of balance. Symptoms can last anywhere from days to weeks.
In the United States, past listeriosis outbreaks—a disease caused by Listeria monocytogenes—have been linked to raw or undercooked poultry, sausages, raw or smoked fish, unpasteurized milk and cheeses, and processed vegetables and fruits.
The longer ready-to-eat refrigerated foods contaminated with Listeria monocytogenes are stored in the refrigerator, the more opportunity the bacteria has to grow, according to the U.S. Food and Drug Administration (FDA).
The Recall
The Seven Seas recall for products sold before March 14, having the lot code R4058 printed on it. According to the company, products from other production codes are not affected by the recall.“The issue was discovered through routine regulatory testing conducted by the Florida Department of Agriculture and Consumer Services. Consumers who have purchased this product with this lot code are being advised not to consume it and return it to the store where it was originally purchased for a full refund,” the announcement said.
A similar recall was issued in November last year when Seven Seas recalled 540 Giant Food Private Label Sockeye Smoked Salmon cases due to potential Listeria monocytogenes contamination.
Listeriosis Infection
Around 1,600 individuals get infected with listeriosis in the United States every year, according to the U.S. Centers for Disease Control and Prevention (CDC).According to the agency, most people affected by listeriosis will require hospital care, with about one in five deaths.
Among pregnant women, listeriosis can result in fetal loss in around 20 percent of cases and newborn deaths in about 3 percent. During pregnancy, the bacteria can spread to the fetus through the placenta.
Tests for the infection will involve checking for Listeria monocytogenes in blood, food, vomit, cerebrospinal fluid, and animal feed. In the case of babies, tests will check the meconium, the infant’s first poop.
Listeriosis is curable. Health care providers will likely prescribe antibiotics to resolve the infection. Antibiotics might be given soon after birth if a baby is born with a listeriosis infection.
