Residues in Other Countries

An overview of the results of the Canadian Veterinary Drug residue control program during the fiscal years 1990/1991-1994/1995 shows that all meat and poultry commodities produced or imported during that period in Canada were totally free of violative residues of many veterinary drugs including chloramphenicol, benzimidazoles, nitrofurans, coccidiostats, zeranol, diethylstilbestrol and

A survey of veterinary drug use and residues in milk has been carried out in Hyderabad, India (34). The results of this survey showed that oxytocin and oxytetracycline were frequently used in veterinary formulations. As a result, a total of 9% of the marketed milk samples and 73% of the individual animal milk samples of the 205 milk samples analyzed in this survey contained oxytetracycline residues. Residual concentrations ranged from 0.2 to 1.4 ppm in marketed milk and from 0.2 to 6.7 ppm in samples obtained from individual buffaloes. In contrast, none of the government dairy samples analyzed was found to contain oxytetracycline residues. Maximum oxytetracycline intake by humans through consumption of such contaminated milk was calculated at the level of0.045 mg/kg body weight (bw)/day. 

Results of a national survey conducted by the Ministry of Health and Welfare on residual antibiotics in domestic meat and fish in Japan for the fiscal years 1990-1992 are presented in Table 13.25. Samples were collected at the urban 

Since over 60% of all antibiotics used in Japan for veterinary purposes are tetracyclines (35), targeted surveys of tetracycline residues in animal tissues have become of particular importance for public health agencies in Japan (36, 37). In 1991, a limited survey in the Aichi prefecture of residual tetracyclines in tissues collected from 64 cattle and 68 hogs of 1358 slaughtered animals that did not pass inspection at slaughterhouses due to presence of disease symptoms was conducted (38). Among 271 kidney, liver, and other organ samples, 49 (18.1%) were positive to oxytetracycline, 5 (1.8%) to chlortetracycline, and 5 (1.8%) to doxycycline, respectively. One cattle kidney sample was positive to both oxytetracycline and doxycycline, whereas tetracycline was not detected in any of the samples.
