Yes, you can take pineapples home from Hawaii, but they must pass a mandatory agricultural inspection by the United States Department of Agriculture before departure. Fortunately, most pineapples purchased commercially at Hawaiian packing facilities or grocery stores are pre-inspected and certified pest-free specifically for air travel, allowing passengers to pack them in checked or carry-on luggage. Inspectors check outgoing baggage to ensure no invasive agricultural pests or soil contaminants are inadvertently transported to the mainland United States.
