Flies, filth and food, part 1
1971
Abstract: Flies are common pests which create a public health menace, but ecological facts of the fly's life cycle give clues to fly control. Flies are attracted by the odors of food preparation, cooking, and decaying garbage and animal wastes (where the eggs are laid). In the 2-4 week life span of the female, 500 eggs may be laid, at preferred temperatures of 80-90 degrees F. Flies carry disease bacteria, fungal spores, tapeworm eggs and protozoan cysts which may be transmitted to food by direct contact. Therefore, fly control depends on sanitation and exclusion. Knowledge of the breeding conditions which could generate enormous fly populations makes it important to kill each fly seen at food establishments or waste facilities. Odors and litter should be eliminated to the extent possible; garbage containers and surface areas should be kept clean, with rubbish sealed within plastic bags. Washrooms must be sanitary. Flies can be screened out with mesh, forced air or electric grids. All food service employees must be aware of, and practice, fly control techniques.
