Oddly enough, the container can be an indicator of a berry gone bad. They explain:
The container they’re in is wet or stained.
That’s probably a sign of overripe, mushy berries in the bottom of the basket. Since you can’t dig through the basket to find out, checking the bottom and sides of the container is a good indicator. Typically there’s a mouldy berry in a container sporting these signs. Your best bet is to pick up a new carton.
Of course, this won’t always be the case, but it may be a sign to at least double check the berries you’re dealing with. For more detail, head to The Kitchn’s full post at the link below.
