ORTIZ Z., César; CONCHA U., Alfredo  and  CAYRO C., Javier. Somatic cell counts in raw milk contaminated withantibiotic residues. Rev. investig. vet. Perú [online]. 2011, vol.22, n.2, pp.151-154. ISSN 1609-9117.

The objective of the present study was to evaluate the somatic cell count (SCC) in raw milk samples contaminated with antibiotics in Arequipa milkshed. A total of 1814 were collected in summer 2009, and 59 of them resulted contaminated with antibiotics. SCC values from contaminated samples were stratified in five levels according to physiological status and milk quality requirements. The average SCC was 1520 ± 1173 x 10 3 cel/ml. Significant differences were found between levels of SCC (p<0.01).

Keywords : antibiotics; milk; SCC; mastitis; subclinical; Arequipa.
