[Maximum residue levels (MRL's) of veterinary medicines in relation to food safety. MRL's really do matter--the Benzaprocpen case].

The importance of veterinary medicines and especially of antimicrobial agents is shown, not only as beneficial compounds for animal health and animal welfare but as risks as well, being potential sources of residues in food of animal origin, when after administration of veterinary medicines to the animals the withdrawal time in relation to the maximum residue limit (MRL) is not taken into account. Health for men and animal is of utmost importance and the quality of food is considered as an important health factor. Data are presented from a report, not made public previously, concerning a study dealing with plasma kinetics and forming of residues in young pigs of a long acting penicillin Benzaprocpen, which was formerly used in the Netherlands quite often in piglets with arthritis. Ten weeks after the last injection with these depot compounds at all injection sites penicillin G residues were present in quantities much greater than the allowed maximum residue limit of 50 micrograms/kg for benzylpenicillin. As a consequence it is impossible to use any longer this specific veterinary medicine in food producing animals and thus MRL's do really matter.

A European farmers' view of free trade and risk assessment for veterinary biologicals.

In Europe, farmers request that they be supplied with the right drug in the right place for the right animal at the right price: no more, no less. They are not concerned which country or company produces the veterinary biologicals used. Farmers are advised by the veterinary practitioner, but knowledge of neither the country of manufacture nor the producer determines their choice. This attitude is due to the quality of the pharmaceutical products available. European farmers support free trade and the implementation of scientific risk assessment. In the view of European farmers, the system of equivalent measurement should be adopted: countries may have different systems to check the quality of veterinary products, but the outcome should be the same, i.e. a guarantee of quality, safety and efficacy.

[Veterinary practice and the environment: what to do and what to omit].

A veterinary practice supplies services and goods, both sections involving acts affecting the environment. Until recently, little attention was paid to the environment, but today far more is known concerning the manner in which veterinary practices should handle the environment. Among other things, this paper will be concerned with the groups of various substances which constitute a menace to the environment, the relevant environmental policy as well as the approach to environmental policy in practice and to the function of the veterinary surgeon as distributor of veterinary drugs respectively. Instruction of the users of veterinary drugs as regards storage and exposure to pollution are discussed. Finally, the economic aspects of a modern environmental policy in veterinary practice are referred to.
