Authorities say a Pima County, Arizona, woman who had a serious underlying health condition has died after eating tainted cucumbers.

County Health Department officials didn’t immediately release the woman’s name or age Friday but said the woman is one of 16 local cases linked to Salmonella poona cases caused by cucumbers grown in Mexico and sold by California-based companies.

They say she died while being treated at a Tucson-area for an illness linked to the Salmonella outbreak.
