Organic food costs consumers extra, sometimes twice as much or more than the "normal" equivalent. This expenditure is justified by the idea that organic foods are healthier. Yet, a Dallas Morning News investigation found that "some organic farmers and plant workers cheat. For example, they spray banned chemicals on their crop, or they raise animals using methods contrary to organic rules." Also, the organizations intended to certify the organic providers sometimes "bend the rules, or they're just woefully unqualified to enforce them." Overseas operations also raise concerns, as they export organic foods, but the USDA is unable to monitor these exports well, and cannot enforce violations.
