Résumé :	Sodium fluoroacetate ( 1080) residues in muscle and liver of free-ranging feral pigs, poisoned with 1080-treated grain in a range of habitats, were determined. The incidence of vomiting, and the degradation of poisoned carcasses were also monitored. The maximum recorded concentrations in muscle (n = 79) and liver ( n = 16) were 2.42 and 4.28 mu g g(-1) tissue, respectively. Mean (+/- s. d.) concentrations were 0.702 +/- 0.535 and 0.635 +/- 1.091 mu g g(-1), respectively. Muscle concentration in pigs sampled within 24 h of death were similar between those pigs poisoned with wheat (0.993 mu g g(-1), n = 21) and malted barley (1.012 mu g g(-1), n = 20) ( P > 0.05), but muscle residues may have been lower in those pigs poisoned with lupin bait (0.178 mu g g(-1), n = 3). Muscle concentrations were also lower in those pigs sampled 24 - 48 h after death (0.481 mu g g(-1), n = 13) ( P = 0.004). There were no differences between the sexes ( northern rangeland: mean, females 0.883, males 0.869 mu g g(-1); agricultural: mean, 0.420 and 0.324 mu g g(-1)) ( P > 0.05), but adult pigs had lower muscle concentrations than did non-adult pigs ( P
