IRAMAIN, M. S et al. Pseudomonas aeruginosa in water and raw milk: preliminary report. InVet [online]. 2005, vol.7, n.1, pp.133-137. ISSN 1668-3498.

The aim of this study was to determine the presence of Pseudomonas aeruginosa in the water used in milking practices and in bulk tank milk, to establish a possible relationship between water and raw bulk tank milk contamination with this bacteria, in dairy farms of Buenos Aires province. Samples from 122 dairy farms were analyzed for P. aeruginosa according to reference methods, getting 111 underground water samples and 92 water storage tank samples and 122 bulk tank milk samples. Twenty seven per cent of underground water samples were positive for P. aeruginosa as well as 34 % of storage tank samples. The bacteria was present in only 4 dairy farms bulk tanks. It was determined that in 3 of them milking management practices allowed the milk to get in contact with contaminated water. Once these practices were eliminated, no P. aeruginosa was found in bulk tank milk samples
