A new pricing study finds that American consumers are facing a “tomato cliff” that will result in huge premiums for fresh tomatoes at the supermarket, or else they will be forced to go without fresh tomatoes, if the U.S. terminates a trade agreement with Mexico at the request of a group of Florida growers.

If Mexican tomatoes are forced to withdraw from the U.S. market, prices for popular varieties such as hothouse tomatoes on the vine would double from national average of about $2.50 a pound to nearly $5 a pound, and grape tomatoes would rise to nearly $5.50 a pound, according to an economic impact analysis by the Nielsen Perishables Group for the Fresh Produce Association of the Americas (FPAA).
