Montana's most valuable agricultural production is in cattle in calves, accounting for almost 1/2 of the state's total agricultural receipts. In the livestock products category, dairy products are important followed by hogs. Sheep and lambs are also raised in Montana.
Unopened, shelf-stable bottled eggnog that contains alcohol can last up to 18 months without refrigeration. Once opened, the alcoholic beverage may last several weeks in the fridge. Homemade eggnog usually lasts for around three days if refrigerated; if at least 5 percent alcohol is added, it may last a few weeks. Eggnog requires consistent refrigeration, so if you leave it out in temperatures of 40 to 90 F for more than two hours, you'll need to discard it.
Just now I went into my kitchen and checked out our Wal-Mart Organic 2% milk. It has an expiration date, but there's also a note saying that the product should be consumed within seven days of opening. Presumably, if you opened the container eleven days before expiration date, you'd still only get the seven days.
