6. Toxicity  The acute toxicity of all Formate materials is low with NO special hazards  Methyl Formate [MF] is transformed very rapidly into formic acid and methanol in the body with a half-life on the order of several seconds.  Formic Acid is present in many foods (18)  fruit juices (30 -100 ppm),  honey (20 -2000 ppm),  wines (1 -340 ppm),  coffee, roasted (1350 -2200 ppm),  coffee, extracts (2000 -7700 ppm),  evaporated milk (30 -400 ppm), and  cheese (20 -200 ppm) (19). (20). (page 14)  The 4-hour inhalation LC50 of methyl formate was > 21 mg/L  All found negative in the Ames test  No further testing is recommended.
