The farm in southwestern Indiana whose cantaloupes were pinpointed late last month as the probable source of a Salmonella outbreak that has sickened 204 people is now recalling its watermelons because they may be contaminated with a different strain of Salmonella. Chamberlain Farms of Owensville, Indiana issued a voluntary recall of this growing season’s watermelons because they may be contaminated with Salmonella Newport. An outbreak of Salmonella Typhimurium was linked to the farm August 22 after samples of cantaloupe collected there revealed the presence of the outbreak strain of the bacteria. Missouri-based Schnucks grocery announced the watermelon recall in a press release Friday. Watermelons subject to the recall that were sold at Schnucks, Logli and Hilander stores outside of Indiana contain a sticker reading “Indian Hills – Product of USA.” Schnucks urges consumers who bought watermelons with these stickers not to eat them and to return them for a full refund. Chamberlain Farms’ watermelons sold at the Schnucks five Indiana locations do not have a sticker. Customers who bought watermelons without a sticker at these stores should return them for a full refund. Only watermelons sold in Schnucks stores before September 7, 2012 are subject to this recall, says the store.
