Data are presented on the sensitivity of foxes to 1080 poison which, although not meeting the requirements for calculation of a precise LD50, provide a basis for determining the appropriate amount of 1080 to use in baits to control foxes. Amounts of 2.5 mg per bait appear ample, based on the lethal dose of c. 0.15 mg per kg for foxes, but further trials may be necessary to confirm whether this provides sufficient allowance for possible reduced bioavailability and reductions in 1080 concentration in meat baits under different environmental conditions.
