Organic Foods: to Buy or Not to Buy?

Conventional vs. Organic: What Is the Difference?
The difference between organic and conventional food begins with the production process. Conventional farmers have the option to use things like pesticides, fertilizers containing synthetic ingredients, sewage sludge (the semi-solid waste by-product from municipal sewage treatment plants), or bioengineering to help produce their crops. Organic farmers do not use these items. Instead, they use strategies like crop rotation, mulching, and manure to help grow their products.
This difference applies equally to plant and animal products. For example, animals used to produce organic products, such as meat, poultry, eggs, and dairy products are not given antibiotics or growth hormones. The following table lists the differences between conventional and organic farming:
How Can I Be Certain My Organic Food Is Really Organic?
The US Department of Agriculture (USDA) has national organic standards for agricultural products. These standards regulate the way all foods bearing the USDA organic label are grown, handled, and processed. The only exception to these standards is small organic farmers who sell less than $5,000 a year in organic foods.
These standards mean that organic products, from anywhere in the country, now fall into 4 categories. Only 2 categories are allowed to display the USDA organic label. The following table lists these categories and outlines what products making these claims may and may not contain.
