(UPDATED COVERAGE, Nov. 24)

Timco Worldwide Inc., Davis, Calif., is recalling 812 cases of its large seedless watermelons because of potential salmonella contamination.

UPDATED: Same customer prompts two separate recalls

The company said in a Nov. 20 news release that cases were shipped to seven customers including grocers, wholesalers and processors in California and Texas. One of the customers conducted the test on the outside rind of a watermelon with the positive result Nov. 19, according to the news release, but two subsequent tests from the same six pallets came back negative.

Rex Lawrence, director of sales and marketing, said the positive test result was found by the same customer who got a separate positive test result for salmonella on another company’s cantaloupes.

“We find it pretty concerning,” Lawrence said of the close timing of the test results from the same customer.

Five Crowns Marketing, Brawley, Calif., also issued a separate recall Nov. 20 based on the customer’s test of its cantaloupes. Both companies are not naming the customer.

Lawrence said there’s no information on a possible source of contamination or how the watermelons came in contact with salmonella.

The Timco watermelons are stickered with the “MelonUp!” label with the PLU No.  4032 and UPC No. 0 33383 40240 6, according to the news release.

Lawrence said no illnesses have been reported and the watermelons are being pulled from distribution. The company said consumers who purchased the watermelons should return them to the place of purchase for a full refund.
