Visitors are required to declare all food products and plants upon entry.
The United States maintains strict control over the importation of fresh and processed food products, particularly when it comes to meat, fruit and vegetables.
Meat and meat bi-products are generally prohibited from non-commercial importation.
Fruit and vegetables are carefully monitored to prohibit the introduction of agricultural pests and diseases. The U.S. maintains that the unmonitored importation of fruits and vegetables from other countries increases the risk of infestation by invasive species. Like Canada, the U.S. also restricts or limits imports based on its commercial industries, which include apple, peach, and other fruit in states like Washington and Oregon.
From time to time, agricultural alerts may also affect the importation of certain fruits or vegetables. It is best to declare ALL of your belongings at the border. The border official may ask you to describe the origin of certain items and will then decide whether they can be imported or whether they present a risk.
The U.S. imposes stiff fines for any prohibited fruits or vegetables that are imported without authorization. U.S. border officials do not take kindly to discovering that one "forgotten" piece of fruit in the middle of the suitcase, so travelers are encouraged to be sure to declare all food products before entering the country.
Some plants can be imported from Canada; however, others may require a special import permit. for more specific information, contact the United States Department of Agriculture (APHIS) website.
