Water for Domestic Animal Drinking Based on the Categorization of Species in an Urban Brazilian Slum

Every animal needs safe water for drinking. The quality of this water is essential for welfare. This study discusses on the quality of water furnished to about 50 domestic animals based on the categorization of species practiced by residents at São Rafael slum, located in the city of João Pessoa, Brazil. The drinking water comes from three sources: municipal supply system, bottled mineral water and directly from the Jaguaribe River. The water perceived as safest was the same as offered to pets. Domestic animal water samples were tested and rated as not recommended in more than 65% of the samples. The density of thermotolerant coliforms ranged between 0 and 11,000 cells/100 mL. One third of the samples considered unsuitable for animal watering were also outside the recommended pH. In addition, a differential behavior was observed in the choice of water source according to the caretaker's perception of safety. Dogs and cats, considered family members, received the same water as consumed by the family. Even these, 38.5% of the samples, were rated as not recommended and represented a risk to the health of all those who consumed it. As well, a need for good practices of hygiene in water management and cleaning of water dishes, tanks and troughs was seen.
