Journal QuackQuack's Journal: Organic Food not always safer than non-organic

fumonisin, a toxin produced by molds that grow on grains in organic cornmeal in the UK. Every sample tested was at least 7X the acceptible limit!
Fumonisin is a known carcinogen, and causes other maladies.
The reason this is a problem for organic corn, is there are no fungicides used.
