A California company is voluntarily recalling cantaloupes in several states, including Colorado, because of possible salmonella contamination.

Fresno-based DFI Marketing Inc. issued the recall as a precaution after salmonella was found on a single sample of cantaloupe during routine testing. The company did not respond to a phone message left by The Associated Press on Sunday.

The U.S. Food and Drug Administration says about 28,000 cartons of bulk-packed product are possibly contaminated. They were packed Aug. 26 and may have been distributed from Aug. 27 to Sept. 10 to almost two dozen states and Mexico.

No illnesses have been reported.

Last year, 33 deaths were associated with a listeria outbreak linked to cantaloupes from Jensen Farms in Colorado.
