Yet same wouldn’t apply to stale beer that went bad after a few days or weeks?

No, it wouldn't. It's very difficult to produce beer where harmful organisms can multiply. Post-fermentation it's an extremely difficult environment for most organisms.

  • Brewed beer can get yeast or bacterial infections, especially if you cannot refrigerate it and don't have the means to sanitize recipients.

    • Yes, it can. But infections by harmful organisms is very difficult to achieve. The common spoilage organisms in beer are all harmless to humans. Here's a good overview http://mmbr.asm.org/content/77/2/157.long

      Just the hops alone stop pretty much all gram-positive bacteria except Lactobacillus and a few other harmless ones.
