Injection and mixing techniques for the preparation of fresh meat baits containing sodium monofluoroacetate (1080) were evaluated. Both techniques produced baits containing variable quantities of 1080. The injection of 1 ml of 6.0-mg ml-‘ 1080 and 0.5 ml of 13.6-mg ml-‘ 1080 solution produced baits containing (mean ± SD) 2.9 ± 0.6 and 3.5 ± 0.5 mg of 1080 respectively; the ranges were 1.9-4.1 and 2.1-4.4 mg respectively. Decreasing the injection volume while increasing the 1080 concentration did not increase the percentage of 1080 recovered from baits. Mixed baits prepared by tumbling with 1 ml of 5.7-mg ml-‘ 1080 and 1 ml of 10-mg ml-I 1080 per bait contained 3.8 ± 1.9 and 5.3 ± 2.1 mg of 1080 respectively, with respective ranges of 1.2-1 1.3 and 1.2-13.2 mg per bait. The injection method produced baits more uniform with respect to the amount of 1080 in the bait. A significant fraction of the 1080 added in both methods of preparation was not found. Experiments showed that this loss was due to biochemical reaction rather than physical loss.
