Residues of amitraz in the tissues, milk and butter of cattle dipped in Taktic

Abstract

Residues of amitraz in the tissues of steers slaughtered 24 and 48 hours after dipping in Taktic ® (0.025% amitraz) were <0.02 mg kg-1. Milk and butter residues from cows dipped in Taktic reached a maximum of 0.01 and 0.1 7 mg kg-1, respectively, 6 hours after treatment, declining to 0.01 mg kg-1 2 days after treatment. Residues in butter collected during a 3-week period from a local dairy products factory were less than 0.01 mg kg-1. Some of the herds supplying the factory were dipped in Taktic.
