Welcome to a culinary adventure where the phrase 10 ways creatively tackling nature’s unwanted guests meets the kitchen counter. Invasive species are the uninvited party crashers of ecosystems—spreading fast, outcompeting natives, and leaving a trail of damage. What if, instead of battling them with traps and chemicals, we invited them to our plates? Below you’ll find a menu of ten daring dishes that not only satisfy curiosity but also give a hand in restoring balance.

From toxic to tasty, slippery to crunchy, each entry shows how a problematic creature can become a sustainable source of protein. Grab your apron, keep an open mind, and let’s explore how to turn ecological troublemakers into culinary triumphs.

10 Ways Creatively Tackling Invasives in the Kitchen

1 Lionfish

Choosing to eat lionfish does more than expand your palate; it sends a clear message about protecting coral reefs. This striking, venom‑spined fish has overrun Atlantic and Caribbean waters, but its flesh is surprisingly mild, flaky, and ready to soak up any seasoning you throw at it. Whether you grill it, fry it, or roll it into sushi, lionfish adapts well to a variety of cooking methods.

Handling the spines requires caution—wear gloves and use needle‑nose pliers to remove them—but once the meat is freed, preparation is as simple as any other fish. By incorporating lionfish into your meals, you directly help curb its numbers, giving reefs a chance to recover while enjoying a truly exotic bite.

2 Wild Hog

Across Texas and much of the United States, wild hogs have become a relentless force, rooting up vegetation and outcompeting native fauna. Yet, when properly prepared, their meat transforms into a hearty, game‑rich delicacy. The key lies in recognizing the distinct, slightly sweet flavor that comes from their varied diet of plants, insects, and small animals.

To make the most of this protein, marinate the cuts to soften the natural gaminess, then employ low‑and‑slow techniques such as smoking or braising. These methods break down tougher fibers, yielding tender, flavorful meat. Safety is paramount—cook the pork to at least 145°F (62.8°C) to neutralize any potential parasites like trichinosis, ensuring a safe and memorable feast.

3 Asian Carp

Asian carp may not be the first fish you picture for dinner, but they bring a surprisingly adaptable texture to the table. Their firm, white flesh carries a subtle flavor that works well with a range of seasonings, and because they sit low on the food chain, they tend to contain fewer contaminants than many other freshwater species.

The biggest culinary hurdle is their intramuscular bone network. Skilled filleting around these tiny structures or opting for recipes that break the fish down—such as battered “Flying Carp Wings”—can turn the bone issue into a crisp, bite‑size treat. Incorporating Asian carp into meals helps manage their booming populations while offering a novel protein source.

4 Snakehead Fish

Don’t let the fierce appearance of snakehead fish deter you; beneath those sharp teeth lies a surprisingly mild, white meat that’s a joy to work with. These predators thrive in U.S. waterways, but their flesh is free of the muddy taste typical of many bottom‑dwelling fish, thanks to a diet of baitfish and insects.

Filleting snakeheads is straightforward, and the lack of tiny bones makes them kitchen‑friendly. Whether you fry them into crisp nuggets, grill them with a simple herb rub, or toss them into a stir‑fry, the result is a versatile, clean‑tasting dish that helps reduce their invasive numbers.

5 Green Iguanas

In South Florida, green iguanas have become a common sight, but for some locals they’re more than a nuisance—they’re a protein‑rich delicacy known locally as “pollo de los árboles” or chicken of the trees. Their lean meat is high in protein and, according to some, even boasts medicinal qualities.

Hunters typically capture iguanas using nets or traps, then roast them whole with the skin on, which makes it easier to peel later. After roasting, the meat is chopped and seasoned with fresh chives, onions, hot peppers, and sometimes curry, yielding a flavor profile that many compare to chicken but with a unique, slightly firmer texture. From burritos to sausages, iguana meat is finding its way onto a variety of plates, turning a pest into a tasty resource.

6 European Green Crabs

Along Washington’s coastline, European green crabs have carved out a niche, devouring native species and altering marsh ecosystems. Though technically edible, their small size and comparatively bland flavor make them a challenging sell for most seafood lovers.

Harvesting these crabs is no walk in the park—they hide in shallow, muddy zones that are difficult to access, and there’s a real risk of unintentionally catching native crab species. Even if enough green crabs are gathered, over‑harvesting could disrupt the very balance we aim to restore, potentially leading to unexpected population spikes among younger crabs. Nonetheless, exploring preparation methods—perhaps a seasoned sauté or a crunchy tempura—could turn this invasive critter into a culinary curiosity worth pursuing.

7 Nutria (Swamp Rat)

Nutria, the orange‑toothed rodents that have ravaged Louisiana’s wetlands, were originally introduced for fur farming but have since become a major ecological menace, gnawing away at vegetation that stabilizes swamp ecosystems.

Chefs such as Philippe Parola are reimagining nutria as a lean, dark‑turkey‑tasting meat, featuring it in dishes ranging from stews to smoked roasts. Because nutria meat is low in fat and high in protein, it serves as a sustainable alternative to traditional livestock, while simultaneously curbing the rodent’s population. Each bite contributes to wetland restoration and showcases a novel, eco‑friendly protein source.

8 Asian Shore Crabs

From Maine down to Florida, Asian shore crabs have slipped into the U.S. Atlantic shoreline, outcompeting native crustaceans and disrupting local food webs. Yet Chef Bun Lai sees a different future for these nickel‑sized invaders, turning them into a crunchy snack at his Connecticut sushi spot, Miya’s.

Collecting the crabs is as simple as strolling along the tide line and picking them off rocks. After a quick freeze to humanely dispatch them, they’re boiled, then tossed into a hot oil bath until they reach a perfect crisp. A splash of lime juice and a pinch of seasoning elevate the natural briny flavor, making these crabs a popcorn‑like treat that helps trim their numbers while delighting adventurous eaters.

9 Jellyfish

Jellyfish blooms are booming across the globe, especially in the Mediterranean, where dwindling predators have let these gelatinous swimmers dominate the water column. Marine biologist Professor Silvio Greco proposed an unexpected solution: turn the stingers into a plate‑worthy ingredient.

At Genoa’s Slow Fish festival, he demonstrated a method of neutralizing the sting by boiling the bellies in lemon juice and vinegar, then giving them a light tempura coating before frying. The result is a crisp, salty bite with a unique, rubbery texture. Rich in protein and practically calorie‑free, jellyfish offer a sustainable, novel seafood option for daring diners.

10 Cane Toads

Cane toads have become a notorious pest down under, decimating native wildlife and spreading toxic secretions throughout Australian ecosystems. The idea of harvesting them for food has crossed many minds, but the reality is far more complicated than simply grilling a few legs.

These amphibians carry potent toxins not only on their skin but also within their muscles, especially the hind legs. Cooking does not reliably neutralize the poison, which can wreak havoc on the heart and cause lasting cellular damage. The variability of toxin levels between individual toads makes any culinary experiment a risky gamble.

While the notion of a free protein source is tempting, the unpredictable nature of cane‑toad toxins renders them unsuitable for consumption. For now, the safest approach remains to avoid eating them altogether, focusing instead on other, less hazardous invasive species.

Before antibiotics turned the tide, the top 10 bacterial infections were responsible for countless fatalities across the globe. Most of us have reached for a prescription at some point to battle a nasty bug, but the microbes listed below still have a knack for turning a simple ailment into a deadly showdown.

Understanding the Top 10 Bacterial Threats

10 E. coli Hemorrhagic Colitis

E. coli are usually harmless residents of our intestines, but a particularly nasty strain can unleash a toxin called Shiga toxin that turns the gut into a battlefield. These bacteria are shed in feces and can hitch a ride on undercooked food or contaminated water, especially where sanitation is lacking.

When the toxin‑producing strain makes its way into the digestive tract, it triggers hemorrhagic colitis – a brutal form of bloody diarrhea that can rapidly dehydrate a person, damage kidneys, and cause serious blood loss, potentially leading to a fatal outcome if left untreated.

Prompt rehydration, both oral and intravenous, is the cornerstone of therapy, allowing the body to flush out the offending bugs while supportive care stabilizes the patient.

While antibiotics are generally avoided for this specific infection because they can worsen toxin release, vigilant fluid replacement remains the primary weapon against this ruthless microbe.

9 Scarlet Fever

Scarlet fever once stalked families in the 18th and 19th centuries, claiming the lives of countless children. Even today, it surfaces sporadically, having claimed the lives of notable figures like Charles Darwin’s offspring.

The culprit is group A beta‑hemolytic streptococci, the same bacteria that cause strep throat. After the initial sore throat and fever, the infection spreads to produce a vivid red, bumpy rash that blankets the body, giving the patient a “scarlet” appearance, while the tongue takes on a strawberry‑like texture.

If the infection spreads unchecked, it can lead to throat abscesses, heart inflammation, and kidney damage, all of which can be fatal. Modern antibiotics easily treat the disease, but delayed or inadequate therapy still poses a serious risk.

8 Tuberculosis

Pulmonary tuberculosis, caused by Mycobacterium tuberculosis, has haunted humanity since ancient times; Egyptian mummies bear its marks. The disease claimed luminaries such as Franz Kafka and Henry David Thoreau.

The bacteria settle in the lungs, where they can lie dormant for years, forming granulomas that wall them off. When the immune system falters, the germs break free, leading to classic symptoms: a persistent, sometimes bloody cough, weight loss, and breathlessness.

In severe cases, the infection spreads beyond the lungs to the kidneys, spine, and other organs, creating a systemic assault that can be devastating.

Known historically as “consumption” or the “white death,” tuberculosis still demands lengthy antibiotic regimens—often six months or more—to achieve cure.

7 Tetanus

Also called “lockjaw” or the “grinning death,” tetanus is a dramatic consequence of dirty wounds, a notorious complication during the Napoleonic wars. The bacterium Clostridium tetani thrives in soil and enters the body through puncture injuries.

Its secret weapon is the tetanus toxin, a neurotoxin that latches onto nerve‑muscle junctions, causing relentless, painful muscle spasms that lock the jaw, grind teeth, and can even force the body into a sustained, involuntary smile.

These spasms are so powerful they may fracture bones, including the spine. Respiratory muscles can become paralyzed, leading to suffocation, while secondary infections add to the mortality risk.

Treating tetanus demands a multi‑pronged approach: muscle relaxants, antibiotics, antitoxin, immune globulin, and intensive supportive care. Without rapid intervention, the disease is a medical emergency.

6 Meningococcal Meningitis

When Neisseria meningitidis invades the protective membranes surrounding the brain and spinal cord, the result is meningococcal meningitis—a terrifying nervous‑system infection that still claims lives, especially across sub‑Saharan Africa.

Patients may present with high fever, severe headache, neck stiffness, visual disturbances, and vomiting if the meninges are involved. Alternatively, the bacterium can cause a bloodstream infection marked by a purplish rash and bleeding into skin and organs.

5 Anthrax

Anthrax, caused by Bacillus anthracis, is more than just a heavy‑metal band name; it’s a formidable pathogen with three distinct clinical forms: cutaneous, inhalational, and gastrointestinal. Its spores are resilient, making the disease a candidate for bioterrorism, as evidenced by the 2001 mail‑letter attacks in the United States.

The cutaneous form produces a painless ulcer that can develop a black eschar; when treated early, it seldom proves fatal.

Inhalational anthrax begins like a flu, but swiftly progresses to chest pain, shortness of breath, and, within days, a fulminant blood infection that is almost uniformly lethal without prompt antibiotic therapy.

Gastrointestinal anthrax follows ingestion of contaminated meat, leading to ulcerations throughout the digestive tract—from mouth to anus—causing severe bleeding and systemic infection.

Beyond these, anthrax spores can breach the blood‑brain barrier, infecting the central nervous system and spinal cord, underscoring its reputation as a truly versatile and deadly adversary.

4 Leptospirosis

Leptospirosis, caused by spiral‑shaped Leptospira bacteria, often flies under the radar because its early symptoms can be vague or even absent. The disease is most common in tropical regions and spreads through animal urine, contaminating water or soil.

When symptoms do appear, they may include jaundice, indicating liver involvement, and kidney failure—collectively known as Weil’s disease—a severe form that can be fatal if untreated.

3 Syphilis

Syphilis, the notorious “great imitator,” is caused by the spirochete Treponema pallidum. It spreads primarily through sexual contact and has haunted humanity for centuries, with famous suspects like Vincent van Gogh and Beethoven possibly having suffered its effects.

The disease unfurls in three stages. The primary stage presents a painless ulcer, or chancre, at the infection site—often unnoticed. The secondary stage brings flu‑like symptoms and a widespread rash, accompanied by hair loss, headaches, and liver inflammation.

If the infection lies dormant for decades, the tertiary stage can erupt, producing disfiguring skin lesions, cardiovascular damage, and central nervous system involvement, including the dreaded “general paresis of the insane.”

2 Toxic Megacolon Associated With Clostridium difficile Colitis

Most of us have endured a bout of diarrhea, but when Clostridium difficile overwhelms the gut’s normal flora, it can trigger toxic megacolon—a frightening swelling of the colon that may culminate in rupture.

The condition causes the colon to balloon dramatically, sometimes necessitating emergency surgery. Even without perforation, the swelling can be so severe that surgeons may need to remove almost the entire intestine to save the patient’s life.

Untreated C. diff infection leads to intense inflammation, fluid loss, and, in worst‑case scenarios, total intestinal resection, underscoring the lethal potential of this otherwise overlooked bacterium.

1 Necrotizing Fasciitis

Often dubbed “flesh‑eating bacteria,” necrotizing fasciitis is a rapid, devastating infection that attacks the fascia and underlying tissue, leading to tissue death and sloughing. A host of bacterial species can cause it, each unleashing enzymes that devour soft tissue.

The disease first made headlines during the U.S. Civil War, when cases of genital‑area necrotizing fasciitis were documented. Today, treatment requires a coordinated effort—surgeons excise the dead tissue, while infectious‑disease specialists administer potent antibiotics, and in extreme cases, amputations become unavoidable.

Survivors often recall the harrowing experience, and the condition remains a stark reminder of how quickly a seemingly minor wound can spiral into a life‑threatening emergency.

Artists across generations and continents have breathed new life into old buildings while preserving their historical integrity through a process dubbed “adaptive reuse.” Though their architectural features are typically maintained, their purposes often shift dramatically: cathedrals become concert halls, windmills become wineries. This list takes a look at 10 of the weirdest and most wonderfully repurposed buildings.

10 From Theatre to Bookstore: El Ateneo Grand Splendid

Book lovers and Broadway nerds, rejoice! Hidden in plain sight on a lively avenue of Barrio Norte, Buenos Aires, is one of the most beautiful bookstores in the world. The building first opened its doors as the Teatro Gran Splendid in 1919, hosting an eclectic array of performers, most famously “King of Tango” Carlos Gardel. Ten years later, the theater underwent its first renovation and became the first cinema to show sound films in Argentina. Upon being threatened with demolition at the turn of the 21st century, the former theater was leased to Grup Ilhsa.

Today, the Grand Splendid’s architectural grandeur has been maintained—or as many may argue, enhanced—to spotlight books instead of performers. El Ateneo Grand Splendid pays homage to its musical legacy, with live piano performances serenading readers as they browse shelves and sip coffee. The frescoed ceilings, sumptuous velvet curtains, and abundant ornamentation of the theater make this bookstore a resplendent escape for bibliophiles, thespians, and architects. ^[1]

9 From Church to Skatepark: Kaos Temple

What was once a spiritual haven for Christians of Llanera, Spain, has become a colorful sanctuary for skaters. The Church of Santa Barbara was built by architect Manuel del Busto in 1912 but soon found itself deserted. After being abandoned for almost a century, the space was reprised in 2007 by the Church Brigade, a collective that transformed the former church into an indoor skatepark.

In 2015, Spanish artist Okuda San Miguel was commissioned through a crowdfunding campaign to paint the church in his distinctive geometric style. Today, bold colors and kaleidoscopic depictions of humans, animals, and nature ornament the building’s original domed ceilings and walls. Where once were pews are now halfpipes and ramps to provide indoor refuge to skateboarders in one of Spain’s rainiest regions. The original façade of the Church of Santa Barbara remains, housing the skatepark’s interior amalgamation of neo-Gothic detail and vibrant contemporary art. Kaos Temple blends old and new to appeal to artists and athletes alike. ^[2]

8 From Railway Station to Museum: Musée d’Orsay

Best known for its expansive collection of Impressionist paintings, Paris’s Musée d’Orsay has another peculiar pull: The museum’s foundation initially served as a train station. The 20th-century station’s artfully anachronistic design can be attributed to a collaborative effort between French architects Émile Bénard, Lucien Magne, and Victor Laloux. Located on the Left Bank of the Seine, it was built to transport visitors to the Paris Exposition of 1900.

After being deemed unsuitable for the increasingly mainstream use of longer trains, the building served several purposes beyond the architects’ original intentions. Before the museum’s inauguration in 1986, it was used as a World War II mailing center and set for several popular films, such as Orson Welles’s The Trial. Today, the Musée d’Orsay’s stunning construction and exhibits by Monet and Renoir have made it one of the world’s most popular museums, with well over a million annual visitors.^[3]

7 From Grain Silo to Rock Climbing Gym: Upper Limits Rock Gym

Bloomington, Illinois, hosts the perfect outing for athletes and agricultural enthusiasts: cylindrical rock climbing walls inside 65-foot-tall (20-meter) grain silos. They transformed the abandoned set of four silos to develop an experience that is both unique and sustainable. Utilizing the foundation of the previously deserted structures, the gym is powered by solar panels. In addition to the interior climbing walls, routes have been added to the 115-foot-tall (35-meter) exterior.

Once a giant in the global grain market, rural Illinois’s skyline is still dotted with silos and grain bins. Rock climbing is just one of several unusual purposes the state’s renovated silos serve. Originally a grain bin in Alvin, IL, the Has Bin Guest House has been converted into a charming bed and breakfast. Meridian Nursery similarly repurposed a Rockford silo to host intimate events in a nontraditional rustic setting.^[4]

6 From Cathedral to Bookstore: Boekhandel Selexyz Dominicanen

This 13th-century Catholic cathedral in Maastricht, Netherlands, was repurposed several times over the past seven centuries before settling on the sprawling bookstore it hosts today. After being consecrated in 1294, the building served as a religious sanctuary for half a millennium. Following the 1794 invasion of the Netherlands, however, the gothic church’s cavernous interior appealed to French dictator Napoleon Bonaparte as a strategic—if excessively ornate—storage space. In more recent history, the cathedral was used for bike storage.

In 2005, the building was transformed by Dutch architects Merkx and Girod into a massive bookstore, its grand architecture and lavish interior design capitalized upon to draw lovers of history, art, and stories to its shelves. Now featuring three stories of bookshelves and walkways underneath stunningly preserved frescoes, the renovated church earned the 2007 Lensvelt de Architect Interior Prize and remains a popular destination for today’s locals and literary tourists.^[5]

5 From Jail to Luxury Hotel: The Liberty Hotel

Dark tourists who find themselves in Boston, Massachusetts, can spend a night in what used to be the storied Charles Street Jail. Constructed in 1851 according to the controversial Auburn penal system, the county jail once housed such inmates as activist Malcolm X and anarchists Sacco and Vanzetti. The overcrowded prison closed after almost a century and a half, but its rich history and charming architecture found a second life in The Liberty Hotel.

The ironically named Liberty Hotel opened in 2007, featuring almost 300 guest rooms alongside the original central rotunda. Guests can dine surrounded by portraits of prisoners at the aptly titled Clink and Alibi restaurants or take a walk in the former prison yard. Curiously, Boston’s Liberty Hotel is just one of several prisons transformed into hotels. Those interested in jail hopping can stay overnight in the former Het Arresthuis jail outside Amsterdam or at a Turkish Four Seasons housed in the former Sultanahmet Prison.^[6]

4 From Bullring to Hotel: Hotel Quinta Real Zacatecas

If the macabre history of Boston’s Liberty Hotel doesn’t strike your fancy, consider traveling to Zacatecas, Mexico, to spend the night in this 19th-century bullring-turned-hotel. Quinta Real Zacatecas hotel was constructed within the 1866 San Pedro bullfighting arena, also known as the Plaza de Toros, which hosted the sport for well over a century. In 1989, fourteen years after the Plaza’s final bullfight, the Quinta Real opened its doors.

Today’s visitors can appreciate the hotel’s preserved Spanish Colonial façade from the courtyard where the bullring once stood. And if your hankering to explore uniquely repurposed buildings hasn’t yet been satisfied, a ten-minute drive will take you to Museo Rafael Coronel. In one of the more niche renovations of historic religious buildings, this museum, housed in the former San Francisco convent, features more than 5,000 Mexican masks.^[7]

3 From Shopping Mall to College: Austin Community College’s Highland Campus

Central Texas students flock to Austin to live and learn within the walls of the former Highland Mall. Once anchored by a JCPenney store, the building is now characterized by its sustainable and tech-based approach to higher education. In a $46 million renovation effort, the 32,000-square-foot (2,973-square- meter) mall property has been transformed to accommodate nursing skills labs, kitchens, a television studio, and other modern facilities for hands-on education.

ACC’s newest campus champions a distinct suburban charm in its maintenance of quintessential mall features and the less traditional banana split sculpture marking the former food court.

The Highland Campus has bolstered the local economy and community by drawing young professionals to the campus’s surrounding area, which, paired with its sustainable design, makes it a compelling choice for the next generation of college applicants.^[8]

2 From Grain Silo to Museum: Zeitz Museum of Contemporary African Art

With their domineering form and non-malleable construction, grain silos seem to lend themselves less to adaptive reuse than many of the other repurposed structures on this list. Yet, from climbing walls to galleries, these agricultural hallmarks have been transformed into a number of cultural institutions, with one of the most successful being the Zeitz Museum of Contemporary African Art (MOCAA).

The early 20th-century silos in Capetown, South Africa, were repurposed in 2014 by Heatherwick Studio to house the public, not-for-profit museum. The Zeitz MOCAA exhibits and preserves both temporary and permanent collections of contemporary art from the African continent and diaspora. The building, built upon a foundation of 42 hollowed-out silos, is a work of art in itself—one that, paired with its storied interior, has made the MOCAA the most visited art museum in Africa.^[9]

1 From Film Set to Theme Park: Popeye Village

This final list item transcends a singular building’s transformation. Built for the 1980 musical comedy Popeye, starring Robin Williams and Shelley Duvall, this former film set has been repurposed as an amusement park. The Maltese village, inspired by the fictional hamlet of Sweethaven, comprised 19 wooden buildings which served as the stomping grounds for the live-action Popeye and Olive Oyl. Following Popeye’s lukewarm media response, the set was abandoned.

Rather than letting the prop village succumb to nature, local entrepreneurs converted the neglected set into a theme park, maintaining the colorful architecture to house water trampolines, restaurants, and a winery, among other attractions. Actors still walk the streets of Sweethaven as the comic book and cartoon characters, but for tourists and comic enthusiasts instead of the camera. Whether you have an appreciation for salvaged infrastructure or simply a soft spot for cartoon sailors, Popeye Village belongs on your Malta itinerary.^[10]
