Why halal meat???

At work.

Okay. :yes:

One is never too young to learn.  Then again I suppose neither CO2 or CO are 'instantly' fatal.

Much cheers.

The problem with CO, comparing to CO2 is that the former poisons the blood while the other just makes pigs faint and easily recover if you delay the death blow enough. Let's put it this way, there was no need to exanguinate a pig by a knife blow so quicly, but the blood would be monoxide locked, probably a thing to look at if meat is going for human consumption.

CO2 is a cheap anestesia, not fatal like CO. They used electric shocks, but those are even worse. In the meat quality I mean.
