ITALIAN JOURNAL OF FOOD SAFETY - 2014 - A survey on Aflatoxin M1 content in sheep and goat milk produced in Sardinia Region, Italy (2005-2013) Abstract In the present work the results of a survey conducted in Sardinia Region on Aflatoxin M1 (AFM1) contamination in milk of small ruminants from 2005 to 2013 are reported. A total of 517 sheep and 88 goat milk samples from bulk tank, tank trucks and silo tank milk were collected. Analyses were performed by the Regional Farmers Association laboratory using high-performance liquid chromatography following the ISO 14501:1998 standard. None of the sheep milk samples analysed during 2005- 2012 showed AFM1 contamination. In sheep milk samples collected in 2013, 8 out of 172 (4.6%) were contaminated by AFM1 with a concentration (mean±SD) of 12.59±14.05 ng/L.

ETHZ_CH 29/06/18 Administering hormones affects DNA “We didn’t find any serious impact on the health of the adult offspring; we saw only slight changes, such as in bone density and the ratio of fat to muscle mass,” Ulbrich explains. However, it remains unclear what long-term effects the epigenetic changes might have, and whether the interaction of the many EDCs humans are exposed to on a daily basis render the situation more acute. “There is an urgent need to observe this phenomenon over several generations in a long-term study,” says the ETH professor. “Epigenetic changes can emerge within just one generation, but in certain circumstances they will continue to be transmitted to succeeding generations.
Rev Iberoam Micol. 2010;27:130-5 Occurrence of aflatoxin M 1 and exposure assessment in Catalonia (Spain) Introduction Aflatoxins are a group of secondary metabolites produced by moulds such as Aspergillus flavus, A. parasiticus and the rare A. nomius.25 Aflatoxin M1 (AFM1) is the main monohydroxylated derivative of aflatoxin B1 (AFB1) formed in liver by means of cytochrome p450-associated enzymes. Mammals that ingest AFB1 contaminated diets excrete amounts of the principal 4-hydroxylated metabolite AFM1 into milk.23 Results of studies on heat processing and storage at low temperature of dairy products affecting the amount of AFM1 indicate that such processes do not cause an appreciable change in the amount of AFM1 in these products.
Innovations Agronomiques 73 (2019), 27-41 Les composés néoformés toxiques et leur remédiation : Focus sur les produits carnés Abstract : Food processing induces chemical reactions that can lead to the formation of process-induced toxicants which will in turn impact the food safety. These reactions are dependent on several factors including the composition of the raw material and the processing conditions. Although process-induced toxicants are generally produced at trace level, the consumer is exposed to them frequently and throughout his life.

The analytical grade methanol (MeOH) and ACN were acquired from Merck (Germany).
