The high price of produce, especially for tomatoes after the deep winter freezes, has attracted more than heightened attention from consumers. A ring of sophisticated vegetable bandits was watching, too.

Late last month, a gang of thieves stole six tractor-trailer loads of tomatoes and a truck full of cucumbers from Florida growers. They also stole a truckload of frozen meat. The total value of the illegal haul: about $300,000.

The thieves disappeared with the shipments just after the price of Florida tomatoes skyrocketed after freezes that badly damaged crops in Mexico. That suddenly made Florida tomatoes a tempting target, on a par with flat-screen TVs or designer jeans, but with a big difference: tomatoes are perishable.

“I’ve never experienced people targeting produce loads before,” said Shaun Leiker, an assistant manager at Allen Lund, a trucking broker in Oviedo, Fla., that was hit three times by the thieves. “It’s a little different than selling TVs off the back of your truck.”
