Chlorophenoxy herbicides are a major herbicide used by Sri Lankan farmers. One common variety of chlorophenoxy herbicides is 4-chloro-2-methyl-phenoxy acetic acid (MCPA). Reports of clinical toxicity of MCPA in humans are limited. To our knowledge, liver damage is a rare manifestation of MCPA poisoning, which has not yet been reported in Sri Lanka. We report a case of a farmer who presented with a heterogeneous pattern of liver damage after being exposed to the MCPA pesticide for six months and who later fully recovered with treatment.
