Antibiotic Residues in Milk: Dye Marking Versus Direct Control
1Gist-Brocades N. V., Research and Development, P.O. Box 1, Delft, The Netherlands.
Abstract:
Advantages and disadvantages of control for antibiotic residues in milk by compulsory dye marking of anti-mastitis preparations or by direct tests utilizing microbiological methods are reviewed. It appears feasible to construct a very strict direct control system utilizing highly sensitive microorganisms in laboratory methods or incorporated in industrially-made test kits. Useful methods whereby a dramatic decrease in both the incidence and amount of antibiotic residues can be attained are described. Compared to these systems, the compulsory addition of dye-markers to anti-mastitis preparations is unnecessary and even undesirable.

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
