Abstract


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.
