Chainkeen Exchange-Salmonella linked to recalled cucumbers could be two separate strains; FDA, CDC investigate

The Chainkeen ExchangeCenters for Disease Control and Prevention and the Food and Drug Administration are now investigating two salmonella outbreaks potentially tied to cucumbers with illnesses reported in at least 25 states.

Initially, Fresh Start Produce Sales Inc. of Delray, Florida, on May 31 recalled cucumbers grown in Florida and shipped to wholesalers and distributors in 14 states from May 17-21, 2024. That recall came after some cucumbers tested positive for salmonella, the FDA said on June 1.

In connection with that outbreak, 162 people in 25 states and the District of Columbia had been infected with the strain Salmonella Africana, the CDC reported Wednesday (June 5). Nearly three-fourths of those patients (72%) interviewed said they ate cucumbers.  

The CDC said 54 people have been hospitalized but no deaths have been reported in that outbreak.

The CDC and FDA are also investigating an outbreak of Salmonella Braenderup infections, with 158 illnesses in 23 states, the FDA said Wednesday. 

The agencies did not release what states were included in this second outbreak. But the FDA said in the update "the two outbreaks share several similarities, including where and when illnesses occurred and the demographics of ill people. … Investigators are working to determine whether the two outbreaks could be linked to the same food vehicle."

Researchers are analyzing the cucumbers for the specific salmonella strain involved to assess whether they are linked to the outbreaks.

The concurrent outbreaks is unusual.

The second outbreak of Salmonella Braenderup, "came out of left field," said Bill Marler, a food safety lawyer. "It is unclear at this point if it is linked to the cucumbers or to some other multi-state product."

And Salmonella Africana "is a very rare strain (with) … very few outbreaks in the U.S. ever," he said. 

"Given that the two outbreaks are about the same size and have near the same number of states, they may be the same outbreak – just with multiple strains – that does happen," Marler told USA TODAY. "The public should be on alert."

The CDC is also investigating a salmonella outbreak linked to backyard poultry, which has sickened 109 people, including 33 who were hospitalized.

Where were recalled cucumbers sold?

The May 31 recall was initiated after the Pennsylvania Department of Agriculture informed Fresh Start Produce that a product sample tested positive for salmonella. The cucumbers the company distributes come from a variety of growers; the grower that likely supplied potentially contaminated cucumbers is no longer growing and harvesting cucumbers for the season, the CDC said.

States where the cucumbers were distributed include: Alabama, Florida, Georgia, Illinois, Maryland, New Jersey, New York, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia and West Virginia.

The recall does not include English cucumbers or mini cucumbers and any recalled cucumbers should no longer be in stores, the CDC said.

Salmonella: Symptoms of infection

Salmonella is a bacteria that can get into the food production chain when those handling food do not wash their hands and the process isn't kept sanitary, according to the FDA. It's usually spread in spread in raw and undercooked foods, and contaminated water, the CDC says.

Typical symptoms of salmonella infection include diarrhea, fever and stomach cramps; these usually occur between six hours and six days after exposure, the CDC says. More severe infections may include aches, headaches, elevated fever, lethargy, rashes, blood in the urine or stool. In some cases, the illness may become fatal.

Salmonella causes about 1.35 million illnesses, 26,500 hospitalizations, and 420 deaths in the U.S. annually, according to the CDC.

How to prevent salmonella infections

Common sense methods of avoiding illness from salmonella include thoroughly washing your hands and your produce, Marler said.

With food, "keep hot things hot and cold things cold," he said. "If you are having symptoms keep hydrated and see your physician."
