Health officials in Rhode Island say cardboard egg crates at DeFusco’s Bakery in Johnston have tested positive for salmonella.

The DOH says they do not know if the salmonella found in the egg crates from DeFusco’s Bakery is the same strain that has made people sick.

The Health Department is sending investigators back to the Johnston location to take additional swabs of counters and food equipment.

The DOH says there are now 56 reported illnesses of salmonella poisoning, up from 39 three 3 days ago; of those, 26 have been hospitalized and 24 have laboratory-confirmed cases of salmonella.
