Secret of Fresh Meat: Carbon Monoxide!

By Alex in Food & Drink on Mar 12, 2006 at 2:02 am

If you ever buy a cut of meat at your friendly neighborhood supermarket, you should but may not want to read this.

OK – so, which steak is older? It’s a trick question, they were bought at the same day but the one on top was packaged in an airtight container with a touch of carbon monoxide to keep it stay red for weeks!

This form of "modified atmosphere packaging," a technique in which other gases replace oxygen, has become more widely used as supermarkets eliminate their butchers and buy precut, "case-ready" meat from processing plants.

    It has been noted elsewhere that this info is from a company that makes an older competing product, CO2 has itself been around for quite a while, and the FDA says it is not a problem after about 20 years of use.

    CO2 isn’t the issue. Deceptive marketing practices is.

    See? CO2 really isn’t the issue.

    Hemoglobin (the stuff in blood that carries oxygen to all of your bits) and myoglobin (the same stuff, only in muscles {ie meat}) has a greater affinity for CO than oxygen. Bad for breathing, good for nice looking steaks I guess.

    not only is using this gas deceptive, what about what it does to the flavor of the meats? wal-mart sells this crap , its tasteless!

    I am about to become a vegetarian. Meat these days is absolute crap. I am on a sodium restricted diet and cannot even find chicken that isnt laced with salt. I guess I am going to have to raise my own livestock, but then we would make pets out of them and not want to kill them to eat. I suspected something funky with the case ready meats when I observed the packages were pressurized and commented at the time that they were probably pumped full of some gas. I wonder if its is safe to drive after you’ve eated a CO steak ?
