World Grain - August 2014 - (Page 86)

FEATURE: DEBUGGING YOUR FACILITY Species spotted While the kinds of pests that attack stored foods have not differed over the years, some are becoming more prevalent. "These pests have been around a long time and haven't changed much," said Mel Whitson, regional manager and degreed entomologist, Central Life Sciences; however, some invasive ant species are now showing up in California and Florida. "While these are aggressive species, they are usually considered secondary pests," he said. Far more destructive are the insects that break through the tough hulls of cereal grains and expose the interior to moisture, mold and fungus. In some parts of the world, grain and rice weevils damage up to 40% of the crop. The insects found in bakeries are usually beetles - the red and confused flour beetles - and the Indianmeal moth, which is very common in grain stores and retail environments, noted Raj Hulasare, PhD, PEng (Canada), senior scientist and product manager, Temp Air, Inc. "In snack food facilities, the species varies according to the type of food stored and processed, with flour, cigarette and warehouse beetles the most common." Stored-product pests are not like rodents and flies because they are not heavily affected by the weather, said Zia Siddiqi, PhD, director of quality systems, Orkin, a subsidiary of Rollins, Inc. "Stored-product pests also don't usually pressure facilities from the outside. Instead, they often hitch a ride into a facility on shipments from suppliers," he said. nating sources of moisture and keeping storage areas cool and well-ventilated will reduce chances of the product becoming vulnerable to pests. Siddiqi recommended keeping storage areas below 65 degrees F because most stored-product pests can't thrive in cooler temperatures. But efforts really count when managing received supplies. Signs of infestation on incoming supplies include webbing, damaged ingre- dients or packaging, visible insect larvae or insects themselves. "If you see signs of stored-product pests, refuse to accept the shipment and notify your supplier immediately," Siddiqi said. "Request a supplier inspection, including the mode of transportation." And don't forget to report such episodes to the pest management service, he added. He recommended storage techniques that keep foods away from walls and at least 6 inches off the floor. When receiving pallet loads, it can be possible for a bag in the interior of the stack to rupture. "This exposes the product to pests," Whitson said. "It also drops flour or crumbs at the foot of the storage rack in areas that may not be readily accessible for cleaning." Whitson offered another tip. "You should be selecting the right-sized package so that you go through it quickly," he said. "The bigger the package, the easier it is to inspect and maintain in pest-free condition." Nothing raises the alarm faster than a contaminated foodstuff. "I've seen situations where the pest appears in the packaged food," Whitson related. A fly that a shopper reports finding inside a bread bag has to get through four air curtains and more than a dozen light traps to reach the packaging area. "You have to go back and look at every possibility that might have allowed that pest in," he advised. "You have to look at the whole program."
