Abstract
Filth was detected in 131 sarnples of surplus-bread flour sold in the city of São Paulo. Two methods for extraction of light filth: pancreatin. and Tween-Versene methods were employed. The pancreatin method seemed to be more sensitive. It was found that 69.4% of the samples were contaminated with insect fragments and 19.8% with rodent hairs. The samples contaminated with insect fragments and rodent hairs are obviously improper for human consumption. The source of rodent hairs was apparently rodent feces which are potential transmitters of infections.
