Uses of Thiabendazole: Thiabendazole is used primarily to control mold, blight, and other fungally caused diseases in fruits (e.g. oranges) and vegetables; it is also used as a prophylactic treatment for Dutch Elm disease and used in treatment of Aspergillus has been reported.As an antiparasitic, it is able to control roundworms, hookworms, and other helminth species which attack wild animals, livestock and humans.Medicinally, Thiabendazole is also a chelating agent, which means that it is used medicinally to bind metals in cases of metal poisoning, such as lead poisoning, mercury poisoning or antimony poisoning. In dogs and cats thiabendazole is also used to treat ear infections. Thiabendazole is also used as a food additive, a preservative with E number E233. For example, it is applied to bananas to ensure freshness, and is a common ingredient in the waxes applied to the skin of citrus fruits.
