(June 6, 11:54 p.m.) A multistate Salmonella Saintpaul outbreak that has been linked to roma and red round tomatoes hasn’t affected f.o.b. prices — yet.

“If the decision continues to be delayed it eventually will,” said Tony DiMare, vice president of the DiMare Co., Homestead, Fla., on June 4.

The New Mexico Department of Health announced a link between tomatoes and more than 30 illnesses in that state on May 31, and state and federal agencies were continuing a traceback investigation June 5. Though New Mexico officials indicated they were looking closely at imported product from Mexico, a Food and Drug Administration spokesman said domestic product had not been ruled out.

More than 90 people in 11 states have been affected.

“Any time these types of things happen, it has a long-lasting effect whether you’re directly involved or not,” DiMare said. “There’s been some cancellation of business from the retail and restaurant level.”

After the FDA advised consumers in New Mexico and Texas not to eat roma and red round tomatoes, at least two retailers — San Antonio-based H.E. Butt Grocery Co., and Cincinnati-based The Kroger Co. — pulled the implicated varieties off their shelves in Texas, according to The Houston Chronicle.

“You can say they’re overreacting,” DiMare said, “but they have the public and a customer base to protect. They have to be concerned with liability issues.”

The FDA stressed that grape and cherry tomatoes and tomatoes on the vine were not implicated in the outbreak. DiMare said that could have a positive effect on demand for those varieties.

As of June 5, the state and federal agencies had not identified a specific variety or the source of the tainted tomatoes. The first illness occurred April 23, and new cases were being reported the first week in June.

Some speculation has centered on Mexican product because a large number of cases have popped up in the Southwest.

Sergio Chamberlain, general manager and sales manager for Meyer LLC, Nogales, Ariz., said the majority of the company’s Mexican tomato volume moved in March and April, and the company was wrapping up its deal the first week in June. He said production is shifting to Baja, which crosses product through San Diego.

Jesse Driskill, president of the Fresh Produce Association of the Americas, Nogales, Ariz., said June 4 that the majority of Mexican tomatoes shipped in the past 30 days had been greenhouse or shadehouse product. However, no method of production has been ruled out as a cause.

“Everyone has implemented good agricultural practices in their fields and good manufacturing practices in the sheds,” he said of Mexican producers. “Everyone I know, both growers and distributors, has a program of some sort in place.”

Ed Beckman, president of the Fresno-based California Tomato Farmers cooperative, said growers in that state had not experienced pushback from customers. He pointed out that the state didn’t begin harvesting tomatoes until May 15, well after the first illness occurred.

Jaime Weisinger, director of sales and purchasing for Custom Pak, Immokalee, Fla., said Quincy, Fla., was the last area in that state still in production, and the company planned to start picking in South Carolina by June 7. Virginia was expected to start in early July, he said.
