Frequency of contamination by psychrotrophs, mesophiles, fecal coliforms, Staphylococcus aureus and Salmonella was investigated in 110 samples of commercially available sardines (Sardinella aurita) in the city of Londrina, Parana. Of the populations sampled, the psychrotrophs and mesophiles in the counts of above 106 UFC/g were present in 30(27,28%) and 68 (61,68%), respectively. Fecal coliforms above 100/g were attained in 36(32, 73%) samples. While, S. aureus in counts of above 106 UFC/g was isolated from 47(42, 72%) of the samples; the presence of Salmonella could be demonstrated through the experimental method used. Foram examinadas 110 amostras de sardinha (Sardinella aurita) coletadas em peixarias, supermercados e feiras-livres de Londrina, Paraná, quanto à contaminação por microrganismos psicotrópicos, mesófilos, coliformes fecais (NMP), Staphylococcus aureus e Salmonella. Destas amostras, 30(27,28%) e 68(61,86%) apresentaram contagem de microrganismos psicro-tróficos e mesófilos, respectivamente, superior a 106 UFC/g. Um número de coliformes fecais acima de 100/g foi evidenciado em 36(32,73%) das amostras. Em 47(42,72%) exemplares foi isolado S. aureus em número superiora 106 UFC/g, sendo que em nenhuma amostra foi isolada Salmonella
