I was listening to the American military radio here in Korea and they invited soldiers to donate blood with some exceptions:
- if you’ve been shorter than 30 days in Korea
- if you got a tatoo in the last 6 months
- if you lived in Europe for more than 5 years
I really wonder what could have happened to someone who lived in Europe for more than 5 years which triggered this particular exception.
My guess is that it’s related to mad cow disease, and it hasn’t been updated in a while? I couldn’t find anything when I searched
Here is ours, and the history behind some of the changes https://www.blood.ca/en/blood/am-i-eligible/changes-donation-criteria-blood-donation
Ah yeah, that sounds about right, the 5 years incubation time and so on. Thanks!
Mad cow disease can (sometimes/possibly) take decades to have an effect. If you are some infected meat and have the wrong genetics you could wind up with a sponge for a brain 30 years later.
Prions are terrifying.
The five years is just due to cumulative risk. Someone decided to make that the cutoff.
Bovine spongiform encephalopathy
Weird that it is entirety of Europe. In Finland it is only asked if you’ve been in or lived in the UK in the 90s iirc.
