That’s OK, just don’t eat the brain. Creamy and buttery brains, yum.
BSE is in US cattle but the FDA refuses to let the industry test and report findings. Most cattle are slaughtered before 4 - 5 years of age. BSE doesn't manifest until later.
No one knows if a cow has 'inherited' BSE from its mother when it goes to slaughter unless it is tested. This is a huge thing that no one wants to admit for fear of destroying the economy.
Eat Bison. If they are slaughtered in a facility 'infected and contaminated with beef slaughtered prions - you will still have a better chance of dodging the BSE bullet.
A large percentage of dementia goes untested - no autopsies - since the procedure for sterilization for prions is expensive - more expensive than the autopsy. The only way to denature prion proteins is to high-heat treat everything - cutlery and all surfaces. Bleach doesn't touch it.
If a female cow gives birth every year to at least one offspring (usually two) from the age of 3 on for 8 years and all are contaminated with BSE and half of all female offspring go to slaughter (the other half breed more) before they manifest symptoms and the mother doesn't show symptoms until she is 10 years of age when she can no longer walk. How many people have eaten BSE contaminated beef? Now multiply that by hundreds of thousands and you get the picture of what we are doing to ourselves in the name of a 'sound economy'.
You can bet your bottom dollar that it's not safe to eat beef, period. Kosher butchering helps but only statistically since it's impossible to determine if a slaughtered cow is contaminated by way of its mother.
