Officials said pre-cut melons distributed by Caito Foods, which is based in Indianapolis, were the likely source of the outbreak.
In a statement, the company said it was “voluntarily recalling the products out of an abundance of caution” and had stopped producing or distributing the affected products while the investigation is underway.
“Because it is possible that products shipped between April 17 and June 7, 2018, could still be on store shelves, this recall extends to both retailers and consumers,” the company said.
The affected products were in clear plastic containers and distributed to stores including Walmart, Costco, Kroger, Walgreens and Trader Joe’s.
Healthy people who contract salmonella can usually recover without treatment after a few days of fever, diarrhea and abdominal cramps. Some cases require hospitalization and the illness can be fatal.
