Abstract The water for human consumption is the main vehicle for the transmission of pathogens that are capable of causing enteric parasitic diseases; therefore, its microbiological control is vital. This work had the purpose of evaluating the bacteriological quality of drinking water, in terms of the presence of total and thermotolerant coliforms, in different Feeding Units in the city of
Recife, Pernambuco State, according to the potableness standards established by Ordinance No. 518 of 2004 of the Brazilian Ministry of Health/ANVISA. Forty water samples were collected in the
Feeding Units located near the UFPE and UFRPE.
The bacteriological tests for research on total and thermotolerant coliforms were carried out in accordance with the protocol of APHA (1995). Of the analyzed samples, 62.5% presented total coliforms and 42.5% thermotolerant coliforms.
According to the results obtained, 62.5% of the samples are not in compliance with the law in force. Key words Drinking water, Total coliforms, Thermotolerant coliforms

Resumo A água de consumo humano é o principal veículo de transmissão de patógenos capazes de causar infecções gastrointestinais, sendo vital o seu controle microbiológico. O presente trabalho teve a finalidade de avaliar a qualidade bacteriológica da água para o consumo humano, quanto à presença de coliformes totais e termotolerantes, em diferentes unidades de alimentação na cidade do Recife (PE), conforme os padrões de potabilidade estabelecidos pela
