Was just reading this when I recalled a news clip from a few years back. If you read your meat package and it says seasoned meat it means it has been treated mechanically. This specifically is either a salt water brine injection or a mechanical tenderising procedure.
Salt bring just means you get more water and less meat the EDA and Spectrum Canada have a tolerance for this and most companies push it to the max.
The mechanical is a textured surface pounding the meat to tenderize it. The issue with this is it is hard to sterilize the uneven surface and it can quickly pass bacteria from one bad piece of meat to thousands of pounds in minutes.
So recall this when working in your kitchen and wash down surfaces often also never keep knives within three feet of your stove.
