Massachusetts and Rhode Island health officials say a peanut butter product is being tested for a possible link to a nationwide Salmonella outbreak that has sickened people in their states. The health departments said Friday three cases have occurred in Massachusetts and one in Rhode Island. They say 29 have been reported nationwide since June 11, and they're investigating along with other states and federal health officials.

The officials said the outbreak may be linked to Trader Joe's Valencia Creamy Salted Peanut Butter Made with Sea Salt, in 16-ounce containers with ``use by'' dates of 5/23/2013 and 6/28/2013. No samples have tested positive for the strain of Salmonella involved, but the company has voluntarily removed it from stores. Consumers are advised to discard it. Health officials say some independent online sites may still be selling it.
