Got Wood.
So I took the question to the AmazingRibs.com science advisor, Dr. Greg Blonder of Boston U. His reply:
------------------------------
Common bacteria, like salmonella, are likely killed or disabled by 10% salt solutions, so a few hours of warm growth in a strong brine is not an issue for salmonella. There are some bacteria that shrug off high salt concentrations, but these are less common. And of course botulism not easily deterred by salt.
HOWEVER, it is wrong to think of meat’s interior as “sterile”. Wishful thinking. Bacterial counts are low, but not zero, and often meat is riddled with parasites. This is why raw tuna must be hard frozen before serving. And, meat contains more than muscle. For example, a pork butt is infiltrated by lymphatic nodes, and these are microbial filters and highways. Salmonella is routinely discovered in the lymph system. Chicken, if mass produced and mechanically gutted, is drenched in gut bacteria. Often the chicken parts are tumbled or injected for tenderness, this drives in microbes.
Now, is this likely a BIG issue? Probably not, at least for a couple of hours of warm salty marinading. But don’t confuse “probably” with “safe”. One day the stars will align the wrong way, and you will catch a roaring case of explosive diarrhea. And a young child might die. So I always cold marinate, and take a little more time.
