Toxins | Year: 2012

Between January 2009 and December 2011, a total of 7049 corn, soybean/soybean meal, wheat, dried distillers grains with solubles (DDGS) and finished feed samples were analyzed for the occurrence of aflatoxins (Afla), zearalenone (ZEN), deoxynivalenol (DON), fumonisins (FUM) and ochratoxin A (OTA). Samples were sourced in the Americas, Europe and Asia. Afla, ZEN, DON, FUM and OTA were present respectively in 33%, 45%, 59% 64% and 28% of analyzed samples between 2009 and 2011. From the 23,781 mycotoxin analyzes performed, 81% were positive for at least one mycotoxin. Results of this survey are provided by calendar year, in order to potentially show different trends on mycotoxin occurrence in distinct years: by commodity type and within the same commodity, and by region, to potentially reveal differences in mycotoxin contamination in commodities sourced in diverse regions. © 2012 by the authors; licensee MDPI, Basel, Switzerland.

Food Additives and Contaminants: Part B Surveillance | Year: 2011

Between February and October 2009, 324 grain, feed and feed commodity samples were sourced directly at animal farms or feed production sites in Middle East and Africa and tested for the presence of A- and B-trichothecenes, zearalenone, fumonisins, aflatoxins and ochratoxin A, or for selected groups of mycotoxins only. Samples were analyzed after clean-up by immunoaffinity or solid-phase extraction followed by HPLC with derivatization where appropriate and fluorescence, UV or mass spectrometric detection. The percentage of positive samples of B-trichothecenes ranged from 0 to 87% of tested samples. The prevalence of fumonisins in the different countries was>50% in most cases. Zearalenone was present in tested commodities from all countries except three. The presence of aflatoxin in analyzed samples varied from 0 to 94%. Ochratoxin A was present in 67% of samples in Sudan and in 100% of Nigerian samples. No A-trichothecenes were found in this survey. © 2011 Taylor & Francis.

During an 8-year period, 17 316 samples of feed and feed raw materials from all over the world were analysed for contamination with aflatoxins, ochratoxin A, zearalenone, deoxynivalenol and fumonisins. Overall, 72% of the samples tested positive for at least one mycotoxin and 38% were found to be co-contaminated. Mycotoxin concentrations were generally low and the majority of the samples were compliant with the most stringent EU guidance values or maximum levels for mycotoxins in feed. However, in their present state these regulations do not address co-contamination and associated risks. Long-term trends are difficult to establish as strong yearly variations were observed regarding mycotoxin prevalence and contamination levels. In some cases unusual weather conditions can be linked with high observed mycotoxin loads. An exception to this rule is South-East Asia, where a steady increase of aflatoxin prevalence has been observed. The percentage of aflatoxin-positive samples in this region rose from 32% in 2005 to 71% in 2011. © 2013 Society of Chemical Industry.

As cereal and protein sources suffer a price increase worldwide, the use of alternative ingredients in feeds has become increasingly appealing to the animal industry. Dried distillers' grain and solubles (DDGS) have been one of the ingredients which demand has dramatically increased over the last few years. In fact, the supply of maize DDGS is expected to increase to about 38.6 mmt by 2019-2020. The presence of mycotoxins in these by-products has been a matter of concern raised by their ubiquitous use. A rule of thumb typically used in the field is that the concentration of mycotoxins in the final by-product is about three times higher than that of the original raw material, which may be scientifically backed up by the fact that the remaining portions within the by-product are those which had a higher concentration of mycotoxins (outer portions of the grain). This paper is the outcome of a five-year study during which a total of 409 maize DDGS samples sourced worldwide were analysed for the mycotoxins of major importance which cause the great negative impacts in animal performance and health: aflatoxins (a sum of aflatoxin B1, B 2, G1, G2), zearalenone, deoxynivalenol, a sum fumonisins B1 and B2 and ochratoxin A. From the total of samples tested, only 2% of the analysed DDGS showed contamination levels below the limit of detection (negative samples). 6% of samples had the presence of 1 mycotoxin only and the majority (92% of the samples) was contaminated with 2 or more mycotoxins. © 2011 Wageningen Academic Publishers.

An important gap in continued sustainability of fish farming is the lack of a proper understanding on digestive function and aquafeeds utilization. The WiseFeed project will focus on this gap using an integrative approach and considering selected key fish species in culture, the feed composition and feeding protocols. The approach in WiseFeed is based on a collaborative effort for advancing both the fundamental physiological knowledge and practical applicability. WiseFeed will build an integrated network of research groups from the academia and partners in SME and large enterprises where the overall aim is to improve performance and sustainability of aquafeeds for fish production. WiseFeed has the following specific objectives: - Develop model that quantifies digestion, absorption and retention efficiency of selected macro nutrients in key cultured fish species - Develop software package to optimize feeding strategies - Elucidate the role and effects of specific amino acids and dietary supplements for enhancing metabolism, growth and N-retention including effects of elevated temperatures due to climate changes. The research that forms the basis for WifeFeed is funded by on-going national R&D projects that constitute the scientific and technical pillars of the current proposal. The secondments will bring external expertise to each of these R&D projects and coordinate efforts among similar and related activities. The secondments also build the competence of each of the participating researchers The practical benefits of WiseFeed will be improved production yield, reduced feeding cost and reduced N-waste from fish farms. The expected added value will be a faster advance in common objectives by facilitating progress and fulfilment of the R&D objectives for each participant. Furthermore, it is also the aim of WiseFish to establish a consolidated network beyond the framework of this proposal to give response to new challenges of the aquafeed industry.
