HOW TO CHECK WHETHER IT IS ORGANIC OR NOT?

Continue with the issue of organic foods, there are some important points in Mayo Clinic about it.  The main issue for the consumers is to check whether a food is organic or not.  So, how could we check that?  The U.S. Department of Agriculture (USDA) has established an organic certification program that requires all organic foods to meet strict government standards. These standards regulate how such foods are grown, handled and processed.  If a food bears a USDA Organic label, it means it's produced and processed according to the USDA standards. The seal is voluntary, but many organic producers use it.  Products that contain at least 70 percent organic ingredients may say "made with organic ingredients" on the label, but may not use the seal. Foods containing less than 70 percent organic ingredients can't use the seal or the word "organic" on their product labels. They can include the organic items in their ingredient list, however.
By the way, in this article, it is denoted that organic and natural do not have the same meaning.  Only foods that are grown and processed according to USDA organic standards can be labeled organic.
