HOLD ON! NOOOO! Not over the counter HP. It's the additive/stabilizers in the HP that can ALSO harm you. NOT MEANT FOR CONSUMPTION. Like the other answer says, There is food grade HP you can obtain through the proper channels that can be used, but again needs to be washed off. Once in a while I would say, mouth rinsing... and so on. Most importantly we also have good bacteria in our stomachs that you will kill off, hence the stomach warnings.
I am a big fan of HP, use is all the time. I sanitize my vegetable with it in my sink filled with water. But it doesn't soak in, and I rinse. It give the veggies and fruit an oxygen boost, and they last longer. I put it in my flowers, or make my own rainwater for plants with it. HPeroxide is also created by nature. I put a sprayer in the little bottles and spray my counters and cutting boards after using chicken or something suspiciously bad or can cross contaminate. It’s an odor neutralizer. Garbage cans and smelly laundry. Mold growing in your basement, I spray it down. It removes fresh blood stains and some old ones. Just don’t use it on fabrics without rinsing; it can bleach over a period of time.
Another method my mother taught me. NOTHING stands up to salt. If something was on the edge of turning bad, she would cover it in salt and let it sit. Not too long, the salt will dry out the meat. Then rinse. Use your nose closely, if it still has an odor, throw it out. Even if you know you will cook it a long time killing the bacteria, you will still taste the rancid flavor. Also try and cut off as much of the fat as you can. The fat goes bad faster than the meat.
My simple philosophy... When in doubt, throw it out. It is cheaper than getting food poisoning.
Lastly, if it is tenderness you want, try Velveting your meat. Did you ever wonder why Chinese Food was so tender? It’s amazing how well it works. An old Asian secret that they really don’t tell you about. I use the water method, not the oil. I can’t have too much fat in my diet for health reasons.
