Conteúdo: | Most Cd consumed by sheep is in the organic form (bound to plant protein), so the values derived by experiments using inorganically-bound Cd are less relevant. The maximum time that sheep can be offered feed containing the legally permitted maximum concentration of Cd before their organs exceed maximum permitted Cd concentrations is therefore 130 days. A sheep?s lifespan can easily exceed 130 days after weaning, and it is therefore not surprising that sheep organs routinely exceed Cd limits. Potential measures to prevent increased risk to human health from dietary Cd of animal origin include preventing the livers and kidneys of older animals entering the human food chain and strict implementation of current legislation. Reducing the animal?s duration of exposure to high Cd feed would be an expensive procedure. Lower limits on Cd concentration in sheep feed would enable the offal of older animals to be included but would be difficult to impose, as herbage that has been regularly fertilized with phosphorus or treated with sewage sludge already sometimes exceeds the legal limit. Routine removal of the liver and kidney of at least mature ewes from the human food chain is desirable in order to reduce human Cd intake.
