What makes food or a farm organic? Are there strict guidelines for what can be called organic?
The FDA has regulations for what food products can be labeled organic and what can't. Typically, these are strict regulations on the use of chemicals anywhere near where the product is grown, whether these chemicals are used for pesticides, fertilizers, and even treatment of illnesses. For organic produce, none of these chemicals can have a chance of appearing on the farm. For livestock, they must both be fed organically, and also be kept free of the chemicals themselves. An organic farm is one that has been inspected and approved as following these regulations. The inspection includes looking to see if chemicals might enter the farms incidently, like pesticide blowing over from the neighbor's yard. Food from these farms can then be sold as organic.
