For its latest World Mycotoxin Survey, Biomin conducted more than 33,000 analyses on 8,452 finished feed and raw commodity samples from 63 countries from January to June 2017. These analyses covered common components used for feed such as corn, wheat, barley, rice, soybean meal, corn gluten meal, dried distillers grains (DDGS) and silage, among others.
最新的世界霉菌毒素调查,Biomin对从2017年1月至6月的63个国家的8,452个成品饲料和原始商品样品进行了超过33,000次分析。这些分析涵盖了用于饲料的常见成分,如玉米,小麦,大麦,大米,豆粕,玉米麸粉,干酒糟(DDGS)和青贮饲料等。

Results of the analyses found that deoxynivalenol (DON) and fumonisins (FUM) are the most common mycotoxins found in feedstuffs.
分析结果发现,脱氧雪腐镰刀菌烯醇(DON)和伏马毒素(FON)是饲料中发现的最常见的霉菌毒素。

The survey details the incidence of the main mycotoxins occurring in agricultural commodities, which include aflatoxins (Afla), zearalenone (ZEN), deoxynivalenol, T-2 toxin (T-2), fumonisins and ochratoxin A (OTA).
调查详细介绍了农产品中发生的主要霉菌毒素的发生率,其中包括黄曲霉毒素(Afla),玉米赤霉烯酮(ZEN),脱氧雪腐镰刀菌烯醇,T-2毒素(T-2),伏马毒素和赭曲霉毒素A(OTA)。

Overall, deoxynivalenol and fumonisins were detected in 81 percent and 71 percent of all samples at average levels of 798 parts per billion (ppb) and 1,840 ppb, respectively. Out of all samples, 52 percent were contaminated by zearalenone. Aflatoxins, T-2 and OTA were present in 26 percent, 19 percent and 18 percent of samples, respectively.
总体来说,脱氧雪腐镰刀菌烯醇和伏马毒素样品检出率分别81%和71%,平均水平分别为798ppm(ppb)和1,840ppb。在所有样品中,52%饲料被玉米赤霉烯酮污染。黄曲霉毒素,T-2和OTA样品中分别为26%,19%和18%。

Ninety-four percent of all samples contained at least one mycotoxin, and 76 percent of all samples contained two or more mycotoxins.
所有样品中,94%的样品含有至少一种霉菌毒素,76%的样品含有两种或多种霉菌毒素。

Europe
With five mycotoxins above the risk threshold, Europe faces a severe mycotoxin contamination risk. The most prevalent mycotoxin in this region was deoxynivalenol, detected in 77 percent of the samples, followed by zearalenone, detected in 58 percent of the samples. One finished feed sample from Spain had a maximum concentration of deoxynivalenol of 28,470 ppb and the highest maximum fumonisins concentration was detected in Russian sample (9,478 ppb).
欧洲
五种真菌毒素高于风险阈值,欧洲面临严重的霉菌毒素污染风险。该地区最常见的霉菌毒素是脱氧雪腐镰刀菌烯醇,77%的样品中检出,其次是玉米赤霉烯酮,58%的样品中检出。来自西班牙的一种成品饲料样品的脱氧雪腐镰刀菌烯醇的最大浓度为28,470ppb,俄罗斯样品中检测到最高的最大伏马毒素浓度(9,478 ppb)。

Asia
In Asia, the average concentration of five mycotoxins was above the risk threshold, indicating that the region faces a severe contamination risk. The most prevalent mycotoxin was fumonisins, detected in 81 percent of samples, followed by deoxynivalenol, detected in 79 percent of samples analyzed. Biomin says, although the incidence of aflatoxins was rather low (34 percent of samples analyzed contaminated with this mycotoxin), the average concentration is worrisome and represents a threat to animals.
亚洲
在亚洲,五种真菌毒素的平均浓度高于风险阈值,表明该地区面临严重的污染风险。最常见的真菌毒素是伏马毒素,在81%的样品中检测到,然后是脱氧雪腐镰刀菌烯醇,在79%的样品中检测到。Biomin说,虽然黄曲霉毒素的发病率相当低(分析的样本霉菌毒素检出34%),但平均浓度令人担忧,并且对动物构成威胁。

North America
North America faces a severe risk of mycotoxin contamination with five mycotoxins above the risk threshold. Deoxynivalenol and fumonisins were the most prevalent mycotoxins in feed samples, detected in 80 percent and 65 percent of samples respectively. Maximum concentrations of deoxynivalenol and fumonisins were very high in this region (11,274 and 28,605 ppb respectively).
北美
北美地区面临着严重危害五种真菌毒素污染的风险,高于风险阈值。脱氧雪腐镰刀菌烯醇和伏马毒素是饲料样品中最常见的霉菌毒素,分别在80%和65%的样品中检测到。该地区脱氧雪腐镰刀菌烯醇和伏马毒素的最大浓度非常高(分别为11,274和28,605 ppb)。

South America
South America faces a severe contamination risk, with five mycotoxins registering average concentrations above the risk threshold. Deoxynivalenol is the most prevalent mycotoxin, and was found in 86 percent of samples, followed by fumonisins and zearalenone, identified in 77 percent and 50 percent of samples respectively. Aflatoxins, T-2 and OTA were detected in 29 percent, 23 percent and 5 percent of samples respectively. South America showed the third highest average concentration of fumonisins worldwide (2,192 ppb) and the highest average concentration of OTA worldwide (22 ppb). The highest fumonisins concentration reported in South America came from a Brazilian corn sample (34,860 ppb).
南美洲
南美洲面临严重的污染风险,五种真菌毒素的平均浓度高于风险阈值。脱氧雪腐镰刀菌烯醇是最常见的真菌毒素,86%的样品中检出;伏马菌素和玉米赤霉烯酮样品检出分别为77%和50%。在黄曲霉毒素,T-2和OTA样品检出率分别为29%,23%和5%。南美洲在世界范围内伏马毒素平均浓度(2,192 ppb)水平第三,全球OTA平均浓度最高(22 ppb)。南美洲伏马菌素浓度最高的来自巴西玉米样品(34,860 ppb)。

Middle East
With four mycotoxins with average concentrations above the risk threshold, the Middle East faces a high contamination risk. The most prevalent mycotoxins in this region were deoxynivalenol, fumonisins and zearalenone detected in 62 percent, 58 percent and 43 percent of samples respectively. The highest maximum concentration detected in Middle East were 8,841 ppb fumonisins and 4,801 deoxynivalenol.
