I just realized I have not seen mold on bread or tortillas for a while. Not that I normally have moldy stuff laying around but my son had a birthday in mid May and I had some hamburger buns that were accidentally left in the trailer. They have a "best before" date of 20 May. they are as soft as the day they were bought and...NO MOLD!! Is this due to global warming or the nuclear fallout of Japan, sunspots? Is this stuff safe to eat? I am not eating the old buns but is the new stuff safe I.E. long term effects? I guess I will just start making my own bread again.
