of animal origin are presented in Table 2. Analysis of variance
of copper concentrations in the food items indicates that the
differences observed in copper concentrations between groups
were statistically significant (p < 0.001).
Croatian legislation has not determined a maximum permitted
copper level in animal products. The provisional tolerable daily
intake (PTDI) for copper, set as a limit for metal intake based on
body weight for an average adult (60 kg body weight), is 3 mg (Joint
FAO/WHO, 1999). Mean copper levels in all analysed samples, with
