Heres something I dug up while doing some research and it scared the fire out of me. So I wanted to pass this on.
Mycotoxins are metabolic by products of fungi which are toxic to both humans and animals.
Mycotoxins contamination is most often in wheat,wheat products, corn, corn products, soybean meal and hulls,barley and oats. The toxins can develop prior to harvest, between harvesting and drying or during storage. Once produced the toxins cannot readily be extracted.
Health problems resulting from these toxins can be cancer, liver desease, desease to the immune system, reproductive problems, and they can adversely effect fetal development.
Even if the processed food we buy is not contaminated when we buy it. It can be contaminated after we open it. Every time we open our dog food we allow oxygen to get in. Oxidation of fats has been shown to cause cancer and other health problems. Warm moist air causes mold to grow on food and Mycotoxins are a by product of mold.
Now we know what the toxin is and where it comes from and hopefully we won't buy a bag thats contaminated but what can we do to keep from contaminating what we open. I did the research and this is what I found.
