The case for eating California’s giant invasive rodents
(The Verge) Two-foot-long rodents called nutria, which can grow as large as 20 pounds, are the latest threat to California’s wetlands. But here’s the good news: they apparently taste great in jambalaya. So naturally, I wanted to try some California-grown rodent for myself.
These raccoon-sized rodents from South America have invaded every continent except Antarctica and Australia, and have set up camp in at least 18 US states. Now, they’ve set their beady sights on California. Over the past year, more than 24 nutria have been spotted in California’s wetlands for the first time since they were eradicated in the 1970s, according to The Sacramento Bee. Some were pregnant females, and others were just babies — a clear sign that they’re multiplying.
…They look tasty enough. A website called Exotic Meat Market compares nutria to dark turkey meat — and one nutria has twice as many drumsticks. But it sounds like finding the right recipe is key to making nutria palatable, according to three filmmakers who sampled nutria for their documentary, Rodents of Unusual Size. One of the filmmakers described nutria sausage as tasting “like a morgue” — but the team agreed that nutria jambalaya is delightful, according to their article for BoingBoing.
There are certainly plenty of dishes I could try. In Louisiana, where people are paid to trap nutria on their land, the state’s department of Wildlife and Fisheries website includes a link to recipes for nutria soups, salads, even nutria à l’orange. The site’s tagline: “Can’t beat ‘em, eat ‘em!” It’s a great idea, in theory. But at least in Louisiana, eating nutria hasn’t been enough to get rid of them. Nearly five million nutria have been removed from the state’s swamps and marshes over the past 15 years.
…there’s something else I discovered: nutria carry a parasite that causes something called “nutria itch.” Whatever nutria itch is, it’s something I am very content to never experience.
So, I guess I can change the slogan of this thread to: "Let them eat crickets, or rodents."
A nutria in a frozen river in Slovenia tries to look inedible, only somewhat succeeds.
