BERLIN: The German government vowed Sunday to get tough after a dioxin poisoning scare led to import bans on some of its farm products, as a survey showed one in five consumers in Europe's top economy avoiding eggs. “This is a big blow for our farmers. They have totally innocently been dragged into this situation by the sick machinations of a few people,” Agriculture Minister Ilse Aigner told the Bild am Sonntag newspaper. “It is tough to shake off the suspicion from the information that we have so far that criminal energy has been combined with an alarming unscrupulousness. “The judiciary has to clamp down hard.” Police last week raided a firm in northern Germany suspected of supplying up to 3,000 tonnes of fatty acids meant only for industrial use contaminated with potentially carcinogenic dioxins to some 25 animal feed makers. Tests on samples from the company, Harles und Jentzsch, showed nine samples out of 20 had dioxin levels higher, or much higher, than permitted, with one 78 times over the legal limit. Tests by the firm itself in March last year had revealed high dioxin levels, but this was not reported to the authorities, the agriculture ministry in Schleswig-Holstein said on Friday. Its 25 customer companies then delivered reportedly up to 150,000 tons of contaminated feed to farms – mostly those producing eggs and rearing poultry and meat – across the country. Germany banned some 4,700 of Germany's 375,000 farms from selling any products while authorities performed tests, destroying more than 100,000 eggs and launching recall actions. Some 700 have since been cleared. – Agence France
