Researched by Jennifer M On November 24, 2000, German agriculture received perhaps the biggest shock of the year - a cow born and raised in Germany tested positive for BSE or bovine spongiform encephalopathy, otherwise known as mad cow disease. This case was soon to be followed by several others, thereby shattering the German claim that its beef was BSE-Free and setting loose a wave of consumer panic in the pre-Christmas season. This discovery further led to political turmoil causing the Minister of Health Andrea Fischer and the Minister of Agriculture Karl-Heinz Funke to resign after the beginning of the year. The Ministry of Agriculture has been re-named the Ministry of Consumer Affairs and Agriculture and the new Minister is the former co-spokesperson for the Green Party, Renate Künast. This new focus on consumer safety undermines the traditionally powerful farmer's lobby, but German Chancellor Gerhard Schröder is determined to push through the new hard line in spite of political pressure, not only from the agro-industrial bosses but also from the opposition CDU/CSU. BSE and its Origins
But just what is BSE anyway? It is caused by an aberrant protein, called a prion, which attacks the brains of cows, turning them literally into sponge-like masses. As early as 1984, scientists found cows in England suffering from a mysterious disease that only in 1987 became known as BSE. The cause of the disease has been traced to feeding English cows meat and bone meal made from sheep cadavers infected with scrapie, a similar disease found only in sheep. BSE is an infectious disease and is transmitted by feeding infected meat products to live animals. There are also indications that it can be passed from mother to child during birth. No evidence exists that the disease can be passed directly from animal to animal, but scientific studies are still extremely lacking in this area. House pets, however, can become infected with BSE from eating contaminated meat products. The main cause of BSE, therefore, is the use of meat and bone meal from infected cadavers (Tiermehl) as feed for cattle. This practice, instituted by the animal feed industry due to its cheap means of production and profit-winning focus, has only been prohibited in the European Union since 1994. Germany and France have been strict opponents of such a ban since its introduction. The question remains: why have so many German cows recently tested positive for BSE? A new study indicates that the milk powder used to feed calves is the culprit, it is made from fat and other substances from dead cows. However, since the discovery of BSE in German cows last November, its use has also come under fire. Since November of last year, a total ban on meat and bone-based feed has been implemented in Germany, and Germany is also now strongly supporting similar bans at the EU-level. The suspiscous milk powder, however, is exempt from this ban because its producers claim that it is only made from animal parts also designated for human consumption, such as fat and scraps left over after trimming cuts of beef. The Human Factor
If the disease stopped at affected cows, this entire scenario might not have created so much turmoil; but it has been scientifically proven that BSE can be passed on to humans through the consumption of infected meat products. Creutzfeldt-Jakob disease, a similar disease found in humans but normally affecting only the elderly, has taken on a new face as a result of humans coming in contact with BSE pathogens. This new version is called new variant Creutzfeldt-Jakob disease (nvCJD) and several cases and deaths have already been identified, over 80 in England alone, affecting people of all ages. There is no cure, nor treatment, nor test to check for accuracy of diagnosis. The only tests available for both humans and cattle can only be accomplished by examining brain tissue after death. Risks of Infection
The contagiousness of BSE has yet to be scientifically researched. More than likely, a certain amount of infected material would have to be consumed before risk of infection increased. This amount, however, is not yet known. Consumption of specific risk materials (SRMs) can significantly increase the likelihood of contracting nvCJD. These include brain, spinal cord, eyes, stomach, spleen, bone marrow and parts of the intestines to name a few. Although it is highly unlikely that muscle tissue contains enough pathogens to cause an infection, infected substances can come into contact with uncontaminated body parts during slaughter and processing. Milk is not currently believed to be an SRM and no cases have been reported where milk served as a carrier of the BSE-causing pathogen. Gelatin, however, is another story due to the fact that it is produced from bone meal. In Germany, it is said that commercial gelatin is produced up to 90 per cent from pork bones. In addition, the aggressive processing of bones to gelatin is also suspected of eliminating the BSE pathogens, however, no specific evidence of this exists.
