I purchased several packages of lox on Thursday at Costco to serve at a brunch on Sunday. We have a brand new fridge in our garage. Yesterday when I opened the fridge it felt cold however it smelled faintly of fish, so I turned it colder. Now it smells fine. So the question is, should I trash the lox and buy more, or is it ok to serve? I'm really not sure what to do here and want to err on the side of caution.
