After the case of the melamine-laced petfood that killed thousands of pets three years ago, US Congress is stepping in to propose legislation that will help prevent petfood contamination from happening again.

The Food Safety Modernization Act is intended to amend the Federal Food, Drug and Cosmetic Act but is still awaiting debate in the Senate.

In the House, the Food Safety Enhancement Act of 2009 was passed July 2009 and would give the Food and Drug Administration more power to prevent contaminations.

Michael Markarian, chief operating officer at the Humane Society of the United States, told the Scripps Howard News Service that the bills will give the FDA additional authority to control recalls and to make sure poisonous materials don't come in from abroad.
