Summary

Four kinds of frozen vegetables have been subjected to filth tests in order to survey their degree of defects in terms of extraneous organic and inorganic materials. Green beans and spinach were analysed using the official AOAC methods. Since the AOAC handbook does not show methods of analysis for artichokes and asparagus, two methodologies have been developed for the latter two vegetables. They have been developed from analytical techniques reported by AOAC for other species of frozen vegetables. The analysed commercial products would not be fit for consumption according to Italian law (no. 283, 1962.04.30). On the contrary, spinach and asparagus could be safely sold, according the food defect levels established for them by the FDA. Insect contamination is related to pre-harvest infestation. Some larvae of Rhyzopertha dominica F. (Coleoptera Bostrychidae), a typical pest of stored products, have been noticed only in spinach. An exiguous amount of rodent hairs have been found in two samples of artichokes, in three samples of green beans, and in one sample of asparagus.
