The Food and Drug Administration is apologizing for a false positive test result that linked Taylor Farms to the current outbreak of Cyclospora. The agricultural company recalled lettuce and prepackaged salad kits in twenty seven states, including Alabama, after the FDA announced its original test results. The State Department of Health says one case of Cyclospora is confirmed in Mobile County and one in the Tuscaloosa area.
The original outbreak in Alabama was confined to the northern part of the state. Three Alabama cases are reportedly linked to international travel and five more were traced to Mexican style restaurants, but not Taco Bell outlets blamed for a number of infections in the northern U.S. Cyclospora is a parasite that gets onto produce before its harvested. Health officials say washing food items like lettuce can help. But, the safest route is to cook produce.
Last week, Federal health officials have identified lettuce from Mexico served at Taco Bell locations across five U.S. states as a source of a widespread outbreak of diarrhea-causing parasite cyclospora. The Centers for Disease Control and Prevention late Thursday warned consumers not to eat shredded iceberg lettuce from Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio and West Virginia. A record number of cyclospora cases have been reported in more than 30 states, and experts have said not every recent U.S. illness might be caused by a single source.
CDC, FDA and public health officials in several states have been investigating a multistate outbreak of cyclospora infections. The illness is not usually life threatening and is typically treated with antibiotics.
Last Thursday, ahead of the federal government's confirmation, Taco Bell issued a statement saying that it had taken “immediate action to voluntarily remove potentially impacted lettuce from a supplier in select states. The affected ingredient from our supplier is being indefinitely removed from our supply chain nationwide and will be replaced within 24 hours in select states.”
In a statement, federal health officials stressed that other “brands, restaurants, retailers, or distribution channels” could be tied to the outbreak as the investigation continues. Michigan investigators are trying to figure out if the lettuce went to other restaurants or stores because many of the ill people said they didn’t eat at Taco Bell, state health officials said Friday.
There is no evidence the outbreak “is related to poor food handling or preparation at any single restaurant or fast-food chain,” Michigan health officials said in a statement.
For that reason, they continue to recommend that consumers purchase whole heads of lettuce instead of pre-washed, bagged lettuce or pre-mixed salad kits. Taylor Fresh Foods said in its statement that no Taylor Farms-branded salad kits contain iceberg lettuce.
Some past outbreaks linked to the company involved products sold under different brand names.
North Carolina health officials on Friday reported their count has now surpassed 300 cases, but said the recent illnesses there are not considered to be linked to the outbreak in and around Michigan. They said the most commonly reported foods include parsley, cilantro and lettuce, but it’s not clear if those ingredients were the source of the infections, they said.
Cyclospora is a microscopic, spherical parasite that commonly causes watery diarrhea “with frequent and sometimes explosive bowel movements,” according to the CDC. Outbreaks tend to occur most often in the late spring and summer.
The heat-loving parasite infects the bowels and spreads through feces. In the past, people have been infected by consuming fruits or vegetables that were exposed to feces-contaminated irrigation water.
The illness, called cyclosporiasis, is less common than foodborne illnesses caused by other germs, including salmonella and E. coli. Many cases are never linked to a specific food or other source and, for years, few U.S. cyclospora outbreaks were reported. But the number started rising about a decade ago, with a particularly notable spike in 2018 and 2019.
Previously, 2019 saw the most reported U.S. cyclosporiasis cases, with about 4,700. The current surge has far surpassed that. Michigan — the apparent epicenter of the current outbreak — is reporting more than 5,000 cases, and more than 2,000 additional probable and suspected cases have been reported in other states.
No deaths have been reported. But Michigan officials say more than 100 people in that state have been hospitalized, and health officials say dozens more have been hospitalized in other states. Experts attribute the increasing trend in cases to climate change and better detection. They also say it’s likely that cyclospora cases historically were underreported, for several reasons.
Some common tests used to check for food poisoning have not been geared to detect cyclospora. Technicians aren’t able to grow the parasite in labs, making it hard to draw evidence from contaminated produce. And it can be hard to figure out what food sick people had in common because sometimes it’s a single ingredient that might be common in multiple recipes — like basil or cilantro.
