Which item is commonly restricted to prevent pest introduction at the border?

• A. Illegal drugs
• B. Certain agricultural products
• C. Fireworks
• D. Personal electronics

Answer: (B)

Pest risk at the border is managed by restricting items that can carry living organisms or disease into the country. Plant materials, fresh fruits and vegetables, seeds, and wood or soil-associated items can harbor insects, eggs, larvae, fungi, or bacteria. Because these pests can hitchhike on or inside such products, they’re commonly restricted and may require inspection, treatment, or a phytosanitary certificate before entry. For example, fresh fruit could bring fruit flies or fungal pathogens, and potted plants could carry nematodes or wood-boring pests. The other items are not primarily restricted to prevent pest introduction: illegal drugs are controlled for health and law enforcement reasons, fireworks are regulated for safety concerns, and personal electronics don’t pose a pest risk to border ecosystems.
