An example of a preventative approach to public health policy is?

The Food Safety Modernization Act of 2011 represents a preventative approach to public health policy as it emphasizes a proactive stance on food safety. This legislation shifts the focus from responding to foodborne illness outbreaks to preventing them before they occur. It includes comprehensive strategies for improving safety across the entire food supply chain, which encompasses everything from farm practices to consumer education.

By requiring food producers to implement preventive controls, conduct risk assessments, and ensure compliance with proper food handling practices, this act aims to significantly reduce the incidence of foodborne diseases. This preventative nature is a fundamental aspect of modern public health policies, as it seeks not only to correct issues after they arise but to eliminate or reduce risks at their source.

In contrast, the other choices, while important in their own right, primarily address regulatory and enforcement measures that react to existing conditions rather than focusing on prevention. This distinction highlights why the Food Safety Modernization Act is aptly classified as a preventative approach.
