Analysis of Foreign Matter in Foodstuffs Using the Light Filth Test: Report 2012-2013.

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.

Foreign Bodies in Dried Mushrooms Marketed in Italy.

The presence of foreign bodies in mushrooms affects their marketability and may result in health risks to consumers. The inspection of fresh or dried mushrooms today is very important in view of the increased consumption of this kind of food. Ten samples of dried mushrooms collected in supermarkets were examined for evidence of entomological contamination by macro and microscopic analytical methods, the so-called filth-test. A total of 49 46 determinations, comprising 15 g of the vegetable matrix, were made. The microscopic filth test consistently detected an irregular distribution of physical contaminants following repeated determinations of the same sample. Visual examination, on the other hand, was not sufficient to ensure a product free of contaminants.

Food allergies in school: design and evaluation of a teacher-oriented training action.

BACKGROUND: Food allergies are perceived as a significant problem in school environments; as a result, a teacher's ability to recognise and deal with allergic reactions is of fundamental importance to protect children's health. This paper includes the results of a study conducted for the purposes of designing, implementing and monitoring a specific set of teacher-oriented communication actions. METHODS: The study involved designing, implementing and assessing five workshops. These workshops were designed on the basis of the analysis of perceptions and information needs investigated by three focus groups (25 teachers). The level of the teachers' knowledge and appreciation of the workshops was evaluated by using two structured questionnaires (n = 158). RESULTS: The teachers feel that they are insufficiently informed about food allergies; this knowledge gap is confirmed by an analysis of their knowledge before participating in the workshops. According to the teachers, the information which would be most useful to them has to do with the practical management of allergies in school. They feel that there is a lack of a professional contact person for precise and reliable information on health issues. The workshops seem to be appreciated as an information method. In addition, there appears to be a need to involve all children in awareness raising activities and education projects on this subject. CONCLUSIONS: There is an urgent need for training actions on food allergies in Italian schools, in particular the communication of practical information regarding the management of allergies and emergencies. More communication between the medical and school staff is, in particular, advisable.

Growth performance in heavy lambs experimentally treated with 17 ß-estradiol.

European and Italian legislation have banned use of growth promoters in livestock since 1988, but epidemiological data show that anabolic drugs are still being used illegally. Recent surveys carried out on the cattle farms in Northern Italy have confirmed the presence of growth-promoting hormones. Authors report data on growth performances in 80 Valle del Belice × Comisana weaned lambs experimentally treated with 17 beta-estradiol with 0.5 ml solution of oil Depot Estradiol ® (containing 5 mg of 17ß-estradiol valerate) by intramuscular injection into the thigh. The experiment was founded by the National Ministry of Health, to validate histological test for surveillance and control of growth-promoting hormones in sheep. This study confirmed the strong correlation between clinical and anatomopathological features and growth performances of treated animals. Otherwise, no significant differences were found on in vivo performance of the lambs. Estradiol treatment showed heavier shoulders and necks on treated lambs, while the loins were significantly lighter. Moreover, lamb-estradiol-treated groups showed lower separable and inseparable fat percentage than lamb-control groups.
