The Mad-Cow Disease Scares Europe

The Mad-Cow Disease is a prion disease, manifested by the damage of central nervous system of neurodegenerative nature and the death of diseased animals.

The disease was first registered in the UK in the 1985-1986. Some evidence suggests its earlier appearance, probably in 1965. It was spread mostly in the UK, where about 200,000 cows got sick mostly aged 3-5 years old.

The peak of incidence in the country, which was in 1992-1993, passed, but over the next 10 years, the disease has spread to other countries. In recent years, the disease is recorded (from a few to hundreds of cases) in most of Europe: in Ireland, France, Portugal, Switzerland, Germany, the Netherlands, Denmark, Italy, etc. Sporadic cases were reported in Oman, Canada, Israel, and Japan.

The disease caused European countries enormous economic damage as a result of the destruction of approximately 4 million heads of cattle. In the UK alone, the damage was from 4.5 to 7 billion pounds. The problem has become social, as it led to the ruin of a large number of farms, a significant reduction in the meat market and the decline in production in a number of light industries.

It is assumed that the causative agent of the mad-cow disease has led to the emergence of a new variant of Creutzfeldt-Jakob disease in humans as a result of getting into the food chain.

The death toll in the UK is about 150 people, also there were deaths in Ireland, France, Italy, Canada, and the USA.

The pathogen is transmitted from sick animals to healthy animals by eating contaminated food. Milk and meat from infected animals are in principle not dangerous as the content of prions is in minor amounts in them.

The spread of the disease in the UK were contributed by the causes of man-made: the increase in the number of sheep and large processing volumes to meat and bone meal; increase in milk production, requiring more early weaning calves and their intensive feeding with meat and bone meal. This led to a mass application in the food chain of this animal feed, which turned out to be contaminated by prions.

In rich countries, the basis for prevention are: preventing import from disadvantaged areas or countries of breeding stock, meat, canned food, semi-finished products, meat and bone meal, etc.; monitor of the procurement of breeding stock and biological tissues, particularly from disadvantaged countries; prohibition to feed animals with meat and bone meal from cattle and sheep; prohibition on the use of feed and additives of unknown origin; a thorough diagnosis for any suspicious case and laboratory monitoring of brain samples of beef cattle, particularly from animals older than 3 years old.
