Chef Philippe Parola and his Asian Carp dish with Tour Eiffel

Invasive species, such as nutria and Japanese knotweed, pose a major threat to native habitats, costing the U.S. an estimated $120 billion annually.

One way to beat them is by eating them! Promoting this idea is the “Eradication by Mastication” event. The fundraiser, now in its second year, was created in response to a national movement of chefs who are experimenting with invasive species dishes.

A cook-off competition, live and silent auctions, and buffet featuring fare made with invasive plant and animal species will take place from 2–7 p.m. on Sunday, Sept. 28 at Zenith Vineyard in Salem, Oregon. Tickets are $75.
