vacuum sealed kielbasa in a hot car for 18 hours - is it still good? I bought vacuum sealed kielbasa yesterday about 6:30 pm. It must have fallen out of the bag in my very hot car and I didn't notice until about 11:45 the next day...Is it still good?
Sounds like you're going to need some new kielbasa. 

Kielbasa isn't fermented, and needs to be refrigerated to stay good. Vacuum sealing reduces the oxygen in the package, slowing down oxidation and inhibiting the growth of some types of bacteria when combined with refrigeration, but that kielbasa won't stand a chance in a hot car.
