Since 1956, malathion has been used for insect control and is often used by municipalities to control mosquito populations. The chemical is considered safe for humans and the environment when used under specific conditions and at specific concentrations.
Malathion is of low toxicity; however, absorption or ingestion into the human body readily results in its metabolism to malaoxon, which is substantially more toxic.[17] In studies of the effects of long-term exposure to oral ingestion of malaoxon in rats, malaoxon has been shown to be 61 times more toxic than malathion.[17] It is cleared from the body quickly, in three to five days.[18] According to the United States Environmental Protection Agency there is currently no reliable information on adverse health effects of chronic exposure to malathion.[19] Acute exposure to extremely high levels of malathion will cause body-wide symptoms whose intensity will be dependent on the severity of exposure. Possible symptoms include skin and eye irritation, cramps, nausea, diarrhea, excessive sweating, seizures and even death. Most symptoms tend to resolve within several weeks. Malathion present in untreated water is converted to malaoxon during the chlorination phase of water treatment, so malathion should not be used in waters that may be used as a source for drinking water, or any upstream waters.
