I opened a pack of Hillshire Farms Smoked Sausage a few days ago for some red beans and rice and only used half. I put the other half in a ziploc bag in the fridge. Is it still good? I don't have the wrapper anymore so I don't know if it has a "use by" limit once it's been opened.
Edit: I think I opened it last Friday... so 6 days. I should toss it , huh?
