A California distributor has begun recalling cucumbers imported from Mexico after they were linked to a salmonella outbreak that has killed one woman and sickened at least 285 others, health officials said.

The Centers for Disease Control and Prevention said the cucumbers were most likely the cause of an outbreak of salmonella poona that began July 3 and has reached 27 states. The bacteria killed a 99-year-old San Diego woman and sent 53 people to the hospital, the federal agency said, and more than half of those infected have been younger than 18.

The agency said multiple investigations had linked the outbreak to cucumbers distributed by Andrew & Williamson Fresh Produce. The company, based in San Diego, announced a recall on Friday that covers cucumbers grown in northern Mexico and sold under the company’s “Limited Edition” label from Aug. 1 to Thursday. Consumers were advised to return the cucumbers or to dispose of them.

“The safety and welfare of consumers is the highest priority for our company,” Fred Williamson, the company president, said in a statement. “We are taking all precautions possible to prevent further consumption of this product and are working to learn if and how these cucumbers are involved in the ongoing outbreak.”
