APPLICATION AND PUBLIC-HEALTH SIGNIFICANC E OF AN ENZYME-IMMUNOSORBANT FOR NEUROLEPTICS

Using a commercial ''Multi-ELISA-Kit'' we were able to detect 3 deriva tives of phenothiazine in the serum or urine of treated pigs with high sensitivity (up to 0.2 ppb). Final concentrations after the end of th e withdrawal time and concentrations in the injection sites (<10 ppb u p to 100 ppm) were measured. Since the injection sites with their high drug concentrations are normally not discovered during post-mortem in spection even though the serum concentrations might be suggestive of d rug application, meat hygenic regulations are considered necessary, e. g. ''only processing meat''.
