Through conventional bacteriological methods, the contamination by Clostridium perfringens was evaluated in the ration and water used in the feeding of poultry chickens from different region of the interior from Sao Paulo. C. perfringens was present in 42 and 30% of the ration samples and waters analyzed respectively. The averages of the countings were 6.7 x [10.sup.2]CFU mL for the samples of water and 3.69 x [10.sub.-2]CFU g for rations. The high frequencies and countings of C. perfringens verified in the rations and in the waters may be associated to the lack of general hygiene in the manipulation and storage of the same ones. These suggests a periodic monitoration of the presence of C. perfringens in these sources, with the purpose of avoiding such pathogen, in view that this organism can provoke an outbreak of necrotic enteritis, and cause great damages in the poultry production. Key words: aviculture, contamination, food, microbiology, quality, Clostridium perfringens. Atraves de metodos bacteriologicos convencionais, avaliou-se a contaminacao por Clostridium perfringens na racao e agua utilizadas na alimentacao e dessedentacao de frangos de corte em diferentes regioes avicolas do interior paulista. C. perfringens esteve presente em 42 e 30% das amostras de racao e aguas analisadas, respectivamente. As medias das contagens foram 6,7 x [10.sup.2]UFC mL para as amostras de agua e 3,69 x [10.sup.-2]UFC g para as de racoes. As altas frequencias e contagens de C. perfringens verificadas nas racoes e nas aguas podem estar associadas a falta de higiene geral na manipulacao e armazenamento dos mesmos. Sugere-se o monitoramento periodico da presenca de C. perfringens nestas fontes, com a finalidade de evitar tal patogeno, em vista que o mesmo pode causar um surto de enterite necrotica levando, assim a grandes prejuizos na producao avicola.
