Technically most recommend only 6 months shelf life for corn meal or corn flour.

What can go rancid or bad in it? It contains the fatty germ of the kernel, which will eventually go rancid unless used quickly or wrapped and frozen. Mold can grow in any grain because it's impossible to remove all liquid from the grain when milling.

Basically oils can go rancid & mold can grow in the flour, not to mention the possibility of "bugs" (often referred to as mealie bugs) getting into the mix.

Rule of thumb is to trust your senses, if it doesn't smell right, look right or taste right it's NOT right!

Refrigerating or freezing your corn meal/flour can help keep it fresh longer but never go beyond the 1 year date or date on the box/bag of the flour/meal you have.
