The cause of the feed scandal in Germany is unclear

Lead: Hamburg: May 29, there is no evidence yet of how organic chicken feed in Germany has been contaminated with potentially carcinogenic chemicals A senior agricultural official said Wednesday "We've been looking for how herbicides get into the food chain, but we don't know where it happened." UWE baertels, director of the Lower Saxony State Department of agriculture, said it was the place where the feed was made Officials suspect that hundreds of thousands of ecologically farmed animals may have eaten animal feed contaminated with herbicides, which may cause cancer and have been banned in Germany About 550 tons of contaminated feed has been distributed to 100 eco farms that produce chicken, eggs and other poultry products Officials said on Wednesday that the feed had already flowed into organic pigs and cattle farms Many poultry meat has entered the food chain, officials said The incident has grown into a scandal in Germany, where consumers are highly interested in food safety Many supermarkets have taken organic food off the counter on Wednesday The existence of illegal drugs in feed wheat has attracted the attention of feed manufacturers The pollution of imported wheat by weeding ether may be one of the reasons Baertels, of Lower Saxony, said in a speech on radio NDR in northern Germany He called for analysis of weeding ethers in imported feed materials He said man-made destruction could also be considered a possibility "It can't be excluded at present, because the substance is concentrated, we found that the content of some samples is very high, which is difficult to explain in the conventional grain processing method." Said baertels In the investigation, officials pointed out that weeder can be easily ordered from the Far East through the Internet A spokesman for the Federal Ministry of Agriculture said Germany had asked other countries in Eastern Europe whether to ban the use of herbicides, and so far the answer has been banned The current investigation not only focuses on organic animal feed, but also conventional animal feed.
