Answer to Question 1
Organic food is food that has been grown without the use of synthetic pesticides, chemical fertilizers, antibiotics, and hormones. Organic food is certified by certifiers that have been approved by the National Organic Program under the Organic Food Production Act. Nothing genetically engineered, irradiated, fertilized with sewage, sprayed with pesticides, grown with growth hormones, or grown with the help of chemical fertilizers can be certified.
