“…Fungi normally grow between 10 and 40°C, over a pH range of 4-8 and at a w level above 0.70. However, it is well known that most fungi can grow in a range of conditions; furthermore, the growth on suitable substrates is not necessary for mycotoxin formation (Magan et al, 2003;Reyneri, 2006;Cheli et al, 2013).…”

The aim of the current study was to investigate biogenic amines and mycotoxins concentrations in baled silage (mainly Poaceae family grasses) prepared in organic and conventional farms and to relate these parameters to fermentative parameters. The mean dry matter (DM) content was 364.10±93.31 and 424.70±95.93g/kg in the silage from organic and conventional farms respectively. The silage samples from organic farms had 17.00% higher (P≤ 0.05) tyramine (TY) than the silage from conventional farms. Conventional farm samples were characterized by 46.00% higher histamine (HIS) (P≤ 0.05), 9.80% higher putrescine (PUT) (P≤ 0.05), 17.30% higher cadaverine (CAD) (P≤ 0.05). Aflatoxins (AFL) (total) and zearalenone (ZEN), T-2/HT-2 concentrations were higher respectively 16.00% (P≤ 0.05) and 13.40% (P≤ 0.05), 1.80% (P≤ 0.05) in the silage prepared in organic farms. Deoxynivalenol (DON) concentration was higher 42.40% (P≤ 0.05) in silage from conventional farms. Volatile fatty acids (VFA), lactic acid, ethanol, pH and ammonia nitrogen showed that the silage samples from organic and conventional farms were of good quality. Our study suggests differences in biogenic amine formation or mycotoxins content in silage from organic and conventional farming, but, overall, the measured values are too low to be relevant for animal health. Furthermore, these differences might as well be due to the difference in dry matter content and plant maturity between the organic and conventional silage samples.Keywords: biogenic amines, mycotoxins, volatile fatty acids, organic farm, conventional farm RESUMO O objetivo do presente estudo foi investigar concentrações de aminas biogênicas micotoxinas em silagem embalada (principalmente gramíneas da família Poaceae) preparada em fazendas orgânicas e convencionais e relacionar esses parâmetros a parâmetros fermentativos.

“…are generally associated with a cool and excessively wet growing season [31,54]. Wheat storage and processing are the major areas where contamination can be managed and mitigated at postharvest level, keeping in mind that postharvest contamination is also the result of preharvest presence of fungal contamination.…”

Latest estimates for world cereal production in 2015 and EU-28 production in 2014 are approximately 2540 and 323 mil tons, respectively. The FAO estimated that the global wheat consumption is about 66 kg/per capita. Among the most important risks associated with wheat consumption are mycotoxins. It has been estimated that up to 25% of the world's crops grown for food and feed may be contaminated with mycotoxins. Despite efforts in controlling fungal growth, mycotoxin co-contamination represents an unavoidable risk, occurring pre-and postharvest and resulting in reduced nutritional value and possible risks for human and animal health. In addition to health risks, mycotoxins have a detrimental effect on the quality and the processing performance of wheat. Mitigation measures to manage the challenge of mycotoxins in wheat include strategies at pre-and postharvest. Preharvest events are predominantly dictated by environmental factors and good agronomic/cultural practices, whereas storage and processing are the major areas where contamination can be prevented at postharvest. Integrating as many management options as possible may minimize the risk of mycotoxin contamination in wheat and wheat products.

This study aimed to determine the presence of major mycotoxins of human and animal importance, namely total aflatoxins, fumonisin, deoxynivalenol, zearalenon, T-2 toxin and HT-2 toxin in samples from corn grown in different regions in Turkey. 770 corn samples in total were taken from Çukurova, Sakarya (Adapazarı), Bursa (Karacabey), İzmir (Torbalı), Mersin (Tarsus), Adana (Kozan) ve Şanlıurfa regions between August and November 2015. 625 of the samples were used for total aflatoxin analyses by LC-MS/MS. For other toxin analyses (Fumonisin B1, Fumonisin B2, DON, Zearalenone, T-2 and HT-2) 29 samples were blended for each toxin. The results showed that the highest contamination and risk arises from fumonisin toxins (2652 µg/kg). Mycotoxin contamination in analysed samples was found to be 1.03%. Total aflatoxin was detected as 3. 44% (1 of 625), total fumonisin as 17.24% (5 of 29) and zearalenon as 6.89% (2 of 29). None of the samples were found to contain more than one of the analysed mycotoxins. Also, no DON, T-2 or HT-2 toxin was found. In conclusion, the findings of our study on corn produced in Turkey shows that in some regions contamination levels of corn by mycotoxins exceed the legal limits. Supplying contaminated corn and corn products to human and animal consumption may result in serious health problems, moreover it is known that some toxicogenic fungi may cause decrease in quality and yield in corn production.  Index Terms-corn, mycotoxin, LC-MS/MS
