Summary for Project title: R7971: Field evaluation of a systems based approach to the reduction of blowfly infestation of traditionally processed fish in tropical developing countries.

Understanding the blowfly lifecycle is helping village fish processors raise the quality of their products. Traditional methods of smoking, drying and salting fish in the tropics are often very unhygienic and between 25% and 90% go bad. Previously, processors were slow to adopt simple hygienic measures, such as disposing of waste, making sure the fish and utensils are clean, preparing brines properly, and drying fish on frames rather than on the ground. But when they understand that maggots in their fish come from blowflies they are quickly converted. The guide to help fisheries authorities and NGOs teach processors how to keep their products safe from blowfly maggots is being widely used in Africa, South Asia and South East Asia.
