A preliminary project was conducted to check the bacteriological quality of the water used in cattle drinking troughs in 23 outdoor farm lots. On all but one farm, the fecal coliform count exceeded 80 CFU/100 ml. The situation was similar for both Escherichia coli and Enterococci bacteria. We were not able to analyze these preliminary results statistically and so were not able to draw specific conclusions or generalize the results. However, the results raised enough concerns to prompt the research team to further investigate the source and extent of the problem, in order to come up with solutions. While cow-calf farms tend to prefer outdoor breeding, poor-quality drinking water can have a direct impact on animal health, and may lead to higher pathogen levels in the environment and at slaughter time, and negative consequences for food safety.
