The main sources of infection are contaminated water or milk and, especially in urban communities, food handlers who are carriers.

. The housefly feeds by depositing a drop of digestive liquid on its food, which may be garbage, excrement, or other filth. Although most of the liquid drop is sucked back again through the insect's tubelike lower lip, or labium, a residue remains that may contain disease-causing organisms from previous meals. Disease is also transmitted on the fly's sticky foot pads and hairy body. Each female lays from 100 to 200 eggs in the garbage or manure on which the white larvae feed. With favorable temperatures, one generation or more per month may be produced. Metamorphosis metamorphosis (mĕt'əmôr`fəsĭs) [Gr.

Common dipteran (Musca domestica), accounting for about 90% of all flies in human dwellings. The adult is dull gray with dirty-yellowish areas on the abdomen. Body size ranges from 0.2 to 0.3 in. (5–7 mm), and the conspicuous compound eyes have some 4,000 facets. Because it has sponging or lapping mouthparts, it cannot bite. It is a problem wherever decomposing organic waste and garbage are allowed to accumulate. Its feet may carry millions of microorganisms, some of which cause diseases, including cholera, dysentery, and typhoid. Some insecticides are effective, but houseflies have developed resistance to others.
