This paper emphasizes the suitability of a systematic residue control, not only how a national monitoring programme may timely detect source of contamination of animal organs with cadmium, but also how a systematic control and procedures may resolve the problem of contamination of foodstuffs. As a result of feeding the pigs with contaminated feed (ω (Cd) = 2.05 to 4.86 mg/kg) the mass fraction levels of this toxic metal in their kidneys ranged between 0.67 and 12.96 mg/kg and those determined in liver ranged between 0.07 and 1.69 mg/kg. The levels of cadmium in all muscle samples ranged between < 0.01 and 0.04 mg/kg. After withdrawal of the contaminated feedmix tissue levels returned to normal (ω (Cd) = 0.19–0.63 mg/kg in kidney, 0.03–0.1 mg/kg in liver and < 0.01 mg/kg in muscle).
