Product Recall

Today on the way to work, I thought I saw a headline that read "Beer Recall." It actually read "Beef Recall" though.
The story explained the discovery of mad cow disease in the United States. Mad cow disease is a condition that causes wasting away of the brain, leading to dementia, loss of coordination, and death.
Now, will somebody please explain to me why they're not recalling beer?
