Local authorities manage the quarantine system of the Galapagos National Park in order to reduce the possibility of foreign species invading the archipelago. All cargo and luggage that arrives to Galapagos National Park or that is transferred from one island to another must be inspected. All aircrafts are disinfected with Permethrin before landing. To preserve human health and the native species of the Galapagos Islands, the following products may not be transferred to Galapagos: fresh vegetables and fruits, animal products and or their derivatives, dairy products, other live animals, pathological samples, dry coffee beans, genetically modified organisms, forest species or their disseminative parts, grass and its disseminative parts, fresh flowers, medicinal plants and their disseminative parts, banana tree leaves, micro-organisms (fungi, bacteria, etc.) soil and sand, and animal vaccines.
