Expired juice?! 😱

Nün

I just accidentally had a gulp of expired juice! After the one gulp, I realized on the second gulp that it tasted off and i spat the second gulp out. It's not carton juice either, it's fresh juice i bought from an organic store (but id fridged it a couple of days).

I cant find anything online about this. Do you know if having expired juice can be bad for my baby?
