Toxicological Information:THIS PRODUCT RELEASES METHLETHYLKETOXIME
(MEKO) UPON HYDROLYSIS. WHEN HYDROLYSIS IS COMPLETE, MEKO WILL NO
LONGER BE RELEASED. IN A CHRONIC ORAL TOXICITY ANIMAL STUDY, MEKO
PRODUCED AN ADVERSE EFFECT ON RED BLOOD CELLS. GROSS
HISTOPATHOLOGIC ALTERATIONS WERE SEEN IN THE SPLEEN, LUNG AND
KIDNEY. IN AN ACUTE DERMAL ANIMAL STUDY, 200 MG/KG CAUSED MILD
HEMATOLOGIC EFFECTS. MEKO DID NOT PRODUCE A MUTA GENIC RESPONSE IN
SEVERAL IN-VTRO AND IN-VIVO MUTAGENICITY SCREENS.
