BRUSSELS (REUTER) - German Farm Minister Jochen Borchert said on Monday that a possible fifth case of Bovine Spongiform Encephalopathy (BSE) in Germany was being examined in a cow whose mother was imported from Britain. An EU veterinary committee is due to report in March on whether maternal transmission from cow to calf is possible and how it occurs. Some people in Germany were calling for the slaughter of all the 3,000 to 5,000 British cattle imported into Germany, he added. Since the mad cow crisis erupted in March 1996 with Britain's disclosure of a link between BSE and its human equivalent, Creutzfeldt-Jakob Disease, Germany has taken the toughest stance on protecting public health. British Farm Minister Douglas Hogg said on Monday that Britain will present plans to the European Union in early February to exempt herds free of mad cow disease from a worldwide EU ban on British beef exports. Hogg said the British parliament will on Tuesday debate the plans, previously expected late January and which, if accepted, would be the first step in easing the export ban following a compromise reached at an EU summit in Florence last June. But the officials said the British proposals would first have to be examined by various EU scientific and multidisciplinary committees before being sent to the European Commission for approval and this could take several months. Dutch Farm Minister, Jozias Van Aartsen, whose country took over the EU presidency on January 1, is expected to read to European Union farm ministers a progress report on discussions on proposals to help restore consumer confidence in beef, stating the proposals for cattle passports and beef labels needed more work. Several member states are pressing for EU financial aid in setting up computerised systems to identify cattle and track their movements and have complained that the January 1998 deadline is too early. Under this plan it would be compulsory for all cattle to wear ear tags and have passports and for farmers to keep up-to- date registers. The European Commission said on Monday it had formally banned the marketing of cosmetic products containing ingredients derived from cattle, sheep and goats. A Commission spokesman said the cosmetics industry had for the past five years banned the use of brain, spinal cord and eye tissue from cattle, sheep and goats. A French parliamentary commission on Tuesday blasted Britain for hiding the full facts about mad cow disease and accused London of trying to blackmail its neighbours. A six-month inquiry set up by the National Assembly (lower house) found "intolerable" lapses in Britain's handling of the affair, inadequate controls by the European Union and a lack of coordination in France, a report issued on Tuesday showed. The report's author, French deputy Jean-Francois Mattei, said there was no question of quickly lifting the embargo on British beef. The report said London had shown neither cooperation nor a sense of its partners' interests. British Prime Minister John Major adopted a policy of non-cooperation, blocking some EU business in Brussels for several weeks to show his frustration before EU leaders agreed a compromise on lifting the ban at a Florence summit last June. So far the European Union says conditions agreed then for a gradual lifting of the global export ban have not been met.
