Pests crossing state lines are regulated by which entity?

• A. Local health department
• B. Department of Transportation
• C. Farmers association
• D. Pest quarantine regulatory agencies

Answer: (D)

Pest quarantine regulatory agencies regulate pests crossing state lines. These agencies have the authority to impose quarantines, issue permits, and inspect or restrict shipments of plants, soil, and other materials that could carry pests or diseases. Their main job is to prevent the spread of invasive pests from one state to another, protecting agriculture and ecosystems. Local health departments handle public health within a locality, the Department of Transportation focuses on transportation systems, and farmers associations are private groups without regulatory authority.
