Albertson’s LLC has warned customers in four states about baby carrots it sells after a supplier discovered the salmonella bacteria in one bag.

Grimmway Farms discovered a single bag of peeled baby carrots in Canada that tested positive for salmonella, Boise, Idaho-based Albertson’s said Friday in a statement. The warning applies to stores in Colorado, Wyoming, South Dakota and Nebraska.

The carrots are no longer on store shelves. There have been no other positive tests or any illnesses or consumer complaints associated with the carrots, the company said.
