Safe drinking water is essential for our livestock in order for them to live a prosperous life. The objective of this research was to determine the quality and safety of drinking water for animals in farms to identify the sanitary conditions of some farms in the villages of the municipalities of El Dorado and Granada (province of Meta, Colombia). A total of 60 animal production systems were selected, and water samples were taken from the extraction and supply points for both animals and humans. The samples were analyzed for their physical and chemical characteristics (pH, Ammonia-Ammonium, Nitrates, and Nitrites) and the microbiological quality (count of aerobic mesophilic organisms and determination of fecal coliforms). The pH values of the drinking water of the animal production systems ranged between 6.0 - 7.2 in Granada and 7.2 - 7.6 in El Dorado. Regarding Nitrates and Nitrites, all the farms' values were considered normal. Ammonia-Ammonium values varied between 0 - 1 ppm in the Granada production system and 0 - 0.5 in the El Dorado production system. The presence of fecal coliform bacteria was found in 100% of the samples. Fifty-eight percent (58%) of the farms in El Dorado presented values ≥ 48,000 CFU/100 ml of aerobic mesophilic microorganisms. In the municipality of Granada, the highest percentage of aerobic mesophilic microorganisms was between 100 - 1000 CFU/100 ml. All animal production systems had their water with poor microbiological quality as fecal coliforms contaminate it. These results expose the risk that this water represents to human and animal health as it is a source of waterborne infectious diseases.
