Multiple grocery store chains have been impacted by a salmonella outbreak linked to cucumbers.

Federal officials are investigating an outbreak that has sickened 68 people in 19 states, while cucumbers distributed to more than half of states have been recalled.

Arizona business SunFed Produce has recalled cucumbers sold Oct. 12-Nov. 26 in more than two dozen states – including at some Walmart, Wegmans, and Albertsons stores – and in parts of Canada because they may be contaminated with salmonella. Costco is the latest business to notify customers it also sold some of the recalled cucumbers.

Of the 33 people sickened who have been interviewed by state and local health officials, 27 (82%) reported eating cucumbers, the Food and Drug Administration said. No deaths have been reported.

Epidemiologic and traceback data display that cucumbers grown by the produce business Agrotato, S.A. de C.V. in Sonora, Mexico, including recalled cucumbers from SunFed Produce, may be contaminated with salmonella and may be making people ill, the Centers for Disease Control and Prevention said Friday. The FDA had also associated SunFed cucumbers with some salmonella infections, or salmonellosis.

“As soon as we learned of this issue, we immediately acted to protect consumers. We are working closely with authorities and the implicated ranch to determine the feasible factor,” said SunFed president Craig Slate in a press release.

Walmart, Costco, Wegmans, Albertsons among impacted grocers

Walmart alerted customers to the recall on Thursday and posted a list of select stores where the cucumbers had been sold. Those stores, the retailer said, were in Arkansas, Arizona, California, Colorado, Hawaii, Idaho, Louisiana, Missouri, Montana, Nevada, Oklahoma, Oregon, Texas, Utah and Wyoming.

Similarly, Wegmans issued a recall on Thursday alerting customers about potential salmonella contamination for seeded cucumbers purchased through Wednesday, Nov. 27. All potentially impacted cucumbers and products had been removed from store shelves, the retailer said.

Albertsons also issued a recall Thursday of vegetable platters and trays (some with hummus), salad and lettuce mix bowls, and sliced cucumbers, the business said in a press release sent to USA TODAY. The products were sold Oct. 18-Nov. 27 at Albertsons, Randalls and Tom Thumb stores in Arkansas, Louisiana and Texas.

Costco posted a recall notice to its website Friday stating it was also affected by the cucumber recall. The wholesaler said customers should immediately examine their inventory and quarantine product subject to recall. Costco said the cucumbers are item #171067, Cucumber 6 ct., and were purchased between Nov. 12 and Nov. 27.

Consumers who have purchased the recalled products may obtain additional information by contacting SunFed’s recall hotline at 888-542-5849, between 8 a.m. and 5 p.m. MST Monday-Friday, according to SunFed.

Symptoms of salmonella infection

Salmonella is a bacteria that can enter the food production chain when the procedure isn’t sanitary and when workers handling food do not wash their hands, the FDA says. Salmonella can be spread via contaminated water errantly used to irrigate crops, according to the Centers for Disease Control & Prevention.

Symptoms of salmonella infection, or salmonellosis, usually occur between six hours and six days after exposure and may include diarrhea, fever and stomach cramps, the CDC says.

Severe infections may include aches, headaches, elevated fever, lethargy, rashes, and blood in the urine or stool. Some salmonella infections 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.

Earlier this summer, a salmonella outbreak linked to recalled cucumbers (not linked to SunFed) sickened at least 449 in 31 states, the CDC said. Other recent salmonella outbreaks have been linked to pet bearded dragons, backyard poultry and basil, the agency says.
