The food sector in the United States (US) is experiencing its biggest changes in decades. This year, Congress passed the Food Safety Modernization Act, updating regulations first implemented in 1938. The act greatly expands the powers of the Food and Drug Administration (FDA), whose new clout now includes food recall authority. Also in 2011, the Dietary Guidelines for Americans, which are revised every five years, were updated to push for healthier diets overall, and especially for children.
