Under no circumstances should you use it, even if it looks and smells
perfectly good.
Don't you know that all tofu manufacturers plant little toxic bombs in
their packages? At exactly 1 minute after midnight on the day after
the expiration date these bombs will disperse all sorts of disease
organisms throughout the product.
Evacuate your domicile immediately and call the hazmat team from the
nearest pay phone.
