I'm not sure about Canada, but in the USA, cattle are processed so quickly that cleanliness becomes an issue. The label you have even warns of it. It may have "passed meat and/or poultry..." (they processed that label so fast they couldn't finish thier sentence), but it goes on to warn of "bacteria that could cause illness".
You might not know, but most cattle are given a $50 or so medical cap. If thier treatment for illness breaches that sum, the cattle is left to fend for survival without medical help. As you can imagine, this means a lot of cattle would die due to disease. Dont worry, that would be too expensive for the cattle industry to handle. They are instead fed food loaded with antibiotics, so as to prevent illness in the first place. The problem is evolution. Bacteria reproduce at an exponential rate, giving rise to antibiotic resistant organisms (superbugs). You, the consumer, will inevitably contract a superbug and have to seek medical treatment (hopefully with a budget higher than $50).
So, how much did that doctor visit cost? In the US, could be quite a bit of money. Certainly more than the $17.70 you saved by buying the beef to begin with.
Also, it was raised in the USA which means grass (laughs) and grain (corn - not the standard diet for a cow - causes bacterial problems in the cow's gut) are not necessarily the only thing being fed to the cow. Go USA!
If this causes an emotional response, I'd first like to ask for you to verify or refute what I've said with cited sources. It's easy to be passionate about a belief, but remember what your goals are. I'm only trying to help. The best way to do that is to get a better understanding of the food you eat.
And specifically for overlandflyer, I know food budgets can be tight. Beans and whole grain rice are some of the least expensive and most nutritious foods available to us first worlders. The third worlds eat these in spades. Their track record for food caused diseases such as hypertension, coronary artery disease, and obesity are incredibly low until they start eating like us.
