  • Surveys by industry groups indicate that an alarming percentage of grain shipments in the Pacific Northwest are contaminated by dead rodents and birds, rodent hairs and droppings, and bird feathers and droppings. The U. S. Food and Drug Administration has recently announced a program intended to prevent contaminated grain for human foods from entering interstate commerce. Such a program, if strictly enforced, will be costly to the farmer who allows his "on the farm" stored grain to become contaminated. The commercial storage operator who accepts such contaminated grain for storage or shipment— or who permits his own premises to become infested—also may take a severe loss. Surveys of grain storage facilities in central and eastern Oregon and in eastern Washington revealed an astounding lack of interest on the part of handlers and growers in keeping grain clean. Most "on the farm" storage operators practiced no rodent control, and less than two-thirds of the commercial storage operators had effective control programs. Keeping birds out of- stored grain was often ignored entirely, although the solution to this problem is comparatively simple. Rodent species responsible for contamination of stored grains in the Pacific Northwest are primarily the brown or Norway rat and the house mouse. The domestic or barn pigeon and the English sparrow are responsible for most contamination of grain by birds in this area. Only the owner or storage operator can prevent contamination of food grains by rodents and birds. Active, persistent, and determined, effort will keep the grain clean. Professional control operators in almost every community are ready to serve the farmer or handler who does not wish to install his own program.
