Isomalathion is an impurity found in some batches of malathion. Whereas the structure of malation is, generically, RSP(S)(OCH 3) 2, the connectivity of isomalathion is RSPO(SCH 3)(OCH 3). It arises by heating malathion. Being significantly more toxic to humans than malathion, it has resulted in human poisonings. [1]
Malathion is an acetylcholinesterase inhibitor, a diverse family of chemicals.Upon uptake into the target organism, it binds irreversibly to the serine residue in the active catalytic site of the cholinesterase enzyme.

Peanut Butter Blossoms. As the story goes, a woman by the name of Mrs. Freda F. Smith from Ohio developed the original recipe for these for The Grand National Pillsbury Bake-Off competition in 1957.
The metabolism of bees and humans is sufficiently different that bees can safely collect nectars from plants that contain compounds toxic to humans. The honey produced by bees from these toxic nectars can be poisonous if consumed by humans. In addition, natural processes can introduce toxic substances into honey produced from nontoxic nectar.
Carbaryl is a cholinesterase inhibitor and is toxic to humans. It is classified as a likely human carcinogen by the United States Environmental Protection Agency (EPA.) [13] The oral LD 50 is 250 to 850 mg/kg for rats and 100 to 650 mg/kg for mice. [8] Carbaryl can be produced using methyl isocyanate (MIC) as an intermediary. [5]
