Types of organic food

Fresh food
Fresh, "unprocessed" organic food, such as vegetables and fruits are purchased directly from growers, at farmers' markets, from on-farm stands, supermarkets, through speciality food stores, and through community-supported agriculture (CSA) projects. Unprocessed animal products like organic meat, eggs, dairy, are less commonly available in "fresh" form.
In Australia[7] and elsewhere[citation needed], organic eggs must be from free-range hens, rather than from battery chickens. Animals for the organic market may not be fed growth hormones or drugs such as steroids or antibiotics.

Chips, cookies, and other snacks are an example of processed food.

[edit] Processed food
Processed food accounts for most of the items in a supermarket. Often, within the same store, both organic and conventional versions of products are available, and the price of the organic version is usually higher (see modern developments). Most processed organic food comes from large food conglomerates[8] producing and marketing products like canned goods, frozen vegetables, prepared dishes and other convenience foods.
Processed organic food usually contains only organic ingredients, or where there are a number of ingredients, at least a minimum percentage of the plant and animal ingredients must be organic (95% in Australia). Any non-organically produced ingredients must still meet requirements. It must be free of artificial food additives, and is often processed with fewer artificial methods, materials and conditions (no chemical ripening, no food irradiation, and no genetically modified ingredients, etc.).
They may also be required to be produced using energy-saving technologies and packaged using recyclable or biodegradable materials when possible.[7]
