The U.S. Department of Agriculture has placed a ban in the personal importation of whole tomatoes and peppers from Canada, according to U.S. Customs and Border Protection.
Canada imports peppers from countries known to have been affected by the so-called false codling moth and tomatoes from countries known to be dealing with the tomato leaf miner. Those pests can cause severe economic damage to American agriculture.
Bringing the tomatoes and peppers across the border in passenger bags and vehicles is prohibited. Sliced tomatoes and peppers entering from Canada may be imported following Customs and Border Protection agriculture inspection. Stenciling or other proof of country of origin on the item or packaging is required for importation.
A certificate of origin is required for commercial shipments.
