If the poisoning is moderate or severe, it results in chest tightness, breathing difficulty, hypertension, abdominal pain, diarrhea, heavy salivation, profuse sweating, or fasciculation. ===Chronic toxicity=== Chronic effect of fenthion has not been reported. ===India=== Fenthion was used in India for more than 30 years as a larvicide for control of mosquito larvae. The compound was on the review list of Central Insecticide Board in India and they decided to ban the product due to high toxicity concerns. All manufacture after January 2017 was banned. Subsequently a complete ban order, barring all import and usage was issued in August 2018. ==External links==
