Rio Grande Valley citrus farmers are facing the Mexican fruit fly quarantine yet again. These small penny sized pests can eat into their profits. A map from the USDA shows the zone where the Mexican fruit fly is affecting Cameron County. Bonnie Elbert’s farm, Loop Farm, is just on the edge of the zone. Being in a zone does not mean all groves are infested though. Farmers like Elbert, whose farms are not affected by the fly, can still sell their goods. If the Mexican fruit fly does show up at Loop Farm, it could mean the end for their business. "It means we can't sell our fruit, simple as that,” Elbert said. “If we can't sell our fruit, this would be the second season. We would probably have to close our doors." As long as the citrus farms in the quarantine zone comply with the USDA guidelines, their fruits should be safe to consume. Source - http://www.freshplaza.com
