Do Meats In Supermarkets Contain Higher Amounts Of Endotoxin?

[extremecheddar]

Ray has talked about the meat in mexico always being fresh and not aged like the meat in the US. We also know that ground meat contains higher amounts of endotoxins than regular meat.

How much of a difference do you think there is in endotoxin content from a animal killed, cooked, and eaten in the same day vs. the meat in the supermarket that sits around for weeks? Even the local grass fed beef at my farmers market is hung and aged for 7 days before it is packaged and frozen. Seems like a lot of time for bacteria to do its thing in dead flesh. Once the bacteria produce the endotoxin in the meat, there is nothing you can do to remove or lower it. Neither cooking or stomach acid will lower the content. Saturated fat may be the vehicle for absorption.

Is there any data comparing endotoxin content of all protein sources and comparing freshness or different preserving methods?

Are there any safe animal protein sources low in endotoxin or should we avoid meat unless very fresh? How about fresh or frozen seafood? Dairy?

Without a doubt, yes. Meat from the grocery is high in ebdotoxin, leftovers even more so. The more exposure they have to air the worse it is so things like ground beef are the worst.

The safest animal protein sources as far as endotoxin is concerned would be eggs and milk.

Would deli meats be even worse? Or no because of the chemicals?

Non grass-fed beef is usually fed grain for the last 180 or so days. So the beef comes from animals not in the best health, and the quality of the beef is certainly not the best.

I'd imagine they are pretty bad just in terms of how much surface has been exposed to air. Not sure if preservatives would reduce the amount of bacteria that is on the surface, it might just preserve the meat from degradation.

Glad I found this thread. I have been eating a lot of ground-beef lately and was feeling very off around the day I ate it.
Feeling mildly sick with irritated bowels.
I have switched to steak and chicken breast if I crave meat.

My crude observation is that fast food burgers always cause some stomach upset, while steak does not. Burgers from upscale places also do not.

I buy grassfed ground fresh beef from Whole Foods. On many occasions they have run out, grab meat chunks from the counter case and go grind it right there. Never had any problems. Ultimately this leads me to believe quality matters and fresh unpackaged ground beef matters @Vinero.
