On Capitalist Decadence and Today's Crisis. Ascendant capitalism. Capital existed before capitalism; markets too, and thus the law of value also. The latter to the extent that labor power was not chained to land, to the extent that it could move to where its yield would be higher.
As you can see, there are lots of variables to answering the how long is hamburger meat good for question. Raw hamburger meat (ground beef) is much more perishable than other cuts of beef and will keep in the refrigerator for only 1 to 2 days. Cooked hamburger meat will keep 3 to 4 days in the refrigerator.
If it has hamburger in it, I would only eat it up to a maximum of one week. If it is just tomato sauce you can reseal it and put it in the fridge for months. It should last 4-5 days with or with out the beef. It will mildly change color along with producing a slight odor when it isn't good anymore. I read somewhere that after something has been opened and refrigerated, eat it within 5 days.
