It is designed so you can locate information by category (e.g. food, health, product safety, your money, and transportation). Each category has subcategories to direct you to areas within each federal web site containing related information.  The site also provides current information on fraudulent and deceptive practices in the marketplace, consumer education and tips, and consumer awareness campaigns.
