-mogwai wrote:.bovine spongiform encephalitis)... it's a prion disease that's specific to livestock. it stays in the brain.
doesn't spread into the meat.
EDIT: correction, there's a new form of bse that CAN be transfered to humans through beef. in humans, it's called nvcjd, creutzfeldt-jakob disease.
spongiform encephalitis= sponge brain
The prions spread throughout the brain, and are believed to be present in the spinal cord.
This is a serious health threat, with a long time between infection and symtoms/onset, so if it is ignored, by the time a large outbreak is seen huge numbers may be infected (similar to HIV/AIDS).
It is the result of modern, high intensity farming practice
particularly the use of animal byproducta and waste in feed for other animals.
it is not believed to be a threat in cattle under 2 years of age (where MOST beef comes from) but older breeding stock and milk cows are used for beef by-products (ground meat/sauage, pet food, etc.)
the current inspect program will prevent human disease, IF EVERYONE in the beef industry follows all the rules.
Unfortunately a number of companies/farmers have volated
the feed and reporting requirements, so the next ten years or so while the potiential infected cattle work their way out of the system is the highest risk time (it's been almost 10 years since the feed regulations went in to effect.)
overall the human risk is very low
bird flu is likely a much higher risk, will almost certainly mutate to easily cross in to humans in the next few years, causing an epidemic, possible panidemic. All the current efforts are designed to delay that as long as possible to allow time for anti-viral stockpiling, and vacine work to be done.
It is spreading MUCH faster than predicted via wild bird migrations and will probably be present worldwide within a year.
unlike nvcjd and aids it is a fast onset disease/illness and local outbreaks of human disease can be contain by quarantine (if we have the political will power to do so)
In the long run everyone will be exposed, part of the population will become (very) ill, some percentage will die, but we will become somewhat more resistant (not really imune as flu viris mutate fairly easily, and it will become a low level threat once again, for another 80-90 years.
