ORTIZ Z., César; VERA A., Ricardo  e  CAYRO CH., Javier. Frequency of β-lactams and tetracyclines in raw milk in the Arequipa milkshed. Rev. investig. vet. Perú [online]. 2008, vol.19, n.2, pp.140-143. ISSN 1609-9117.

The objective of the present study was to evaluate the frequency of β-lactams and tetracyclines in raw milk samples contaminated with antibiotics in the dairy area of Arequipa. A total of 616 milk samples were collected in October 2007, and 99 of them were contaminated with antibiotics. Among them, the frequency of samples containing b-lactams and tetracyclines was 88.8 and 61.6% respectively. The number of samples contaminated with b-lactams was statistically higher as compared to those contaminated with tetracyclines (p<0.01). The study showed that antibiotics belonging to the b-lactams group are an important source of contamination of milk in the dairy area of Arequipa.
