摘要：The European legislation set the new hygiene standards in food chain with the purpose to ensure high levels of public health protection in relation to food production. In order to guarantee excellent hygiene standards in food chain, particular attention must be paid to the presence of foreign matter, like light solid impurities of mineral, vegetable or animal origin. The light filth test is a suitable method used to detect and count light solid impurities applicable to different foodstuffs. We report the results of the analysis of 93 foodstuffs official samples investigated for the presence of foreign matter at the Institute for Experimental Veterinary Medicine of Sardinia, from 2012 to 2013. Insect fragments were found in a sample of semolina and in a sample of canned tomato; plastic fragments were found in a sample of grated bread.
