Most farmers who grow organic food need their harvest to be reach and untouched by pests. And large industrial farming companies take it as an essential condition for making profits on agriculture. The greater part of the corn and some wheat grown in the US is targeted for livestock. To keep food for animals safe, companies use a lot of pesticides as well as genetic engineering. Pesticides do not merely protect harvest, they also help animals to stay resistant to intestinal parasites. Nevertheless, chemical compounds accumulate in water and soils as well as in animal tissues and milk.
The health danger linked to the pesticides intake is linked to neural and endocrine disorders. Complications in the prenatal development, as well as cancer, are also claimed to happen because of the high concentration of pesticides in human blood and tissues. But not only high doses of pesticides are dangerous; constant exposure to these chemicals may lead to many other disorders which, however, are not yet properly researched by scientists.
The use of pesticides is regulated by the U.S. Environmental Protection Agency. It establishes the admissible amount of chemicals which does not harm humans while remaining in food. The Food and Drug Administration controls the amount of pesticides in fruits and vegetables while the Department of Agriculture monitors meat, dairy, and eggs. Both EPA and FDA are criticized for high admissible levels of chemicals which remain in products and improper monitoring of the food supplied to the market. Researchers say that average Americans including children have high levels of pesticides due to the standards admissible by EPA.
