Illegal Wildlife Trade Thrives on Facebook, Internet Forums
By Ajit Niranjan
The lizards are frantic and the turtles plodding, but both scrabble to escape the perspex containers that hold them. The reptiles, some in small boxes and fetching prices of up to thousands of euros, are on sale at the Terraristika — Europe's largest reptile trade fair and a suspected wildlife-trafficking hub.
Thousands of enthusiasts descend on the German city of Hamm four times a year to buy exotic creatures ranging from coin-sized glass frogs to tarantulas and venomous snakes. In the wild, some of these animals are becoming dangerously scarce.
As well as the physical marketplace, the Terraristika is a center of a global online community of reptile traders and hobbyists. Customers browse animals on the web and collect them at the fair, sometimes on the unsupervised fringes of the event. Sellers arrange pickups via Facebook groups, owners share care tips on internet forums and YouTubers post videos of themselves "unboxing" animals bought at fairs.
The researchers found most adverts in internet forums, not social media, but they also saw closed Facebook groups with names suggesting they are used to trade reptiles.
Visitors to the Terraristika can buy all kinds of reptiles, including snakes.
DW also found endangered reptiles for sale in Facebook groups such as 'Terraristika Hamm — "MARKTPLATZ"' and 'Hamm and Houten Reptile Classifieds.'
Some of the species on offer are listed under the Convention on International Trade in Endangered Species (CITES), an agreement signed by 183 countries that restricts trade in threatened wildlife. The animals were not necessarily poached — specimens of endangered species are often bred in captivity — but conservation groups fear that, because online trade is so difficult to regulate, endangered animals are being trafficked online.
In one group, a buyer complained that lizards he'd bought over Facebook didn't survive being delivered by post. "Pay me 1200 euro [sic]," he wrote in a private message to the seller accompanied by a laughing emoji, a screenshot of which he posted in the group. "You sent dead animals."
Hiding in Plain Sight
Facebook refused multiple requests for comment. Confronted with screenshots, a spokesperson from a PR firm acting on the company's behalf thanked DW for "sharing the examples of groups advertising endangered animals." Facebook then deleted the groups.
Facebook's commercial policy states that posts may not promote the sale of animals. It is a member of the Coalition to End Wildlife Trafficking Online, a partnership between internet companies and conservation groups, along with tech giants such as eBay, Baidu and Google.
But conservation groups fear the ease with which live animals can be bought on Facebook and other platforms has opened up the market for smugglers. Online wildlife trade is an "extreme problem" because it makes endangered animals available to "every normal person," said Katharina Lameter, a biologist at conservation group Pro Wildlife.
Some reptiles traded online are subject to bans or regulations under the CITES convention.
"That means anyone can advertise, there can be an incredible number of species on offer and anyone can buy these animals without ever having seen them. Often the animals are shipped off or picked up at reptile trade fairs," Lameter told DW.
Unlike drugs or weapons, wildlife is rarely traded on the darknet, a corner of the internet used to anonymously buy illegal goods — and what does appear there is mostly body parts such as elephant tusks, rhino horns and pangolin scales. Live animals are scarce, with traders preferring regular platforms that have access to bigger markets.
"Cybercrime is under the spotlight because the internet is an easy platform to place and to offer illegal goods anonymously … including wildlife," said Sergio Tirro, head of environmental crime analysis at Europol. "It's easy to hide the financial flow by using a prepaid card."
Legal loopholes also cause headaches for law enforcement trying to catch traffickers in the act. For instance, Germany is at the center of the illegal trade in Sri Lankan reptiles, according to an investigation published in April by wildlife trade monitoring group TRAFFIC.
More than half of Sri Lankan reptile species are threatened and the government has banned the export of almost all live reptiles. But they are not all protected internationally under CITES, meaning animals smuggled over in violation of Sri Lankan law can be freely traded in Europe.
Traffic found species "extremely vulnerable to overexploitation" being sold in Facebook groups and classified reptile forums. The number of online adverts offering endangered reptiles, including those endemic to Sri Lanka, rises in the run-up to the quarterly Terraristika fair.
Reptiles are popular pets and trade happens on and offline, like at this fair.
In the bustling warehouse where the Terraristika takes place, sellers eagerly describe their species' "exotic" origins — Sri Lanka, Mexico, Vietnam — but say the specimens they offer were bred in captivity in Europe, not smuggled from abroad.
But with deals taking place in nearby car parks, hotel bars and under tables at the fair itself, authorities struggle to police this. Styrofoam boxes of reptiles change hands off-site before the fair has even begun. Traders who arrange car park deals over the internet need not register a stall with the Terraristika organizers or submit themselves to checks in order to find buyers.
Terraristika did not respond to a request for comment. In a public statement in August responding to questions from German news agency dpa, Terraristika said it works with authorities to prevent illegal activities, but was not responsible if animals were misclassified with false documentation, just as an antiques market could not guarantee vendors wouldn't offer stolen goods.
Yet the internet and digital media are also being used in the fight against illegal wildlife trafficking. Europol's Sergio Tirro said customs officers often take photos of suspicious specimens and send them immediately to experts to identify. Reptiles such as turtles can have minor physical differences between species that are endangered and not.
"You don't need to see the animal physically," said Tirro.
"When you have very precise pictures you can detect it. You don't need to travel all around the world to see if an animal belongs to a protected species."
And not all internet platforms are affected. DW did not find reptiles for sale on eBay, which said its open marketplace does not lend itself to trade in living creatures because every posting is completely public. Conservation groups confirmed this.
Ebay said it uses algorithms to search for suspicious keywords and alert human enforcers who can remove them. Some terms such as ivory are automatically banned by block filters, so sellers receive a warning message as soon as they try to post an advert with a banned word.
It's unclear if Facebook uses similar methods, but DW found several posts offering endangered species by typing the animals' Latin names into the Facebook search bar.
Conservation groups encourage tougher rules and stricter enforcement from internet platforms. But they caution that as one platform cracks down on wildlife trade, traders simply move to others that are less regulated.
"It would be best if online trade in live animals were completely banned," said Lameter from Pro Wildlife.

Why You Should Wash Fresh Produce<p>Global pandemic or not, properly washing fresh fruits and vegetables is a good habit to practice to minimize the ingestion of potentially harmful residues and germs.</p><p>Fresh produce is handled by numerous people before you purchase it from the grocery store or the farmers market. It's best to assume that not every hand that has touched fresh produce has been clean.</p><p>With all of the people constantly bustling through these environments, it's also safe to assume that much of the <a href="https://www.healthline.com/nutrition/fresh-vs-frozen-fruit-and-vegetables" target="_blank">fresh produce</a> you purchase has been coughed on, sneezed on, and breathed on as well.</p><p>Adequately washing fresh fruits and vegetables before you eat them can significantly reduce residues that may be left on them during their journey to your kitchen.</p><p><strong>Summary</strong></p><p><strong></strong>Washing fresh fruits and vegetables is a proven way to remove germs and unwanted residues from their surfaces before eating them.</p>
Best Produce Cleaning Methods<p>While rinsing fresh produce with water has long been the traditional method of preparing fruits and veggies before consumption, the current pandemic has many people wondering whether that's enough to really clean them.</p><p>Some people have advocated the use of soap, <a href="https://www.healthline.com/nutrition/white-vinegar" target="_blank">vinegar</a>, lemon juice, or even commercial cleaners like bleach as an added measure.</p><p>However, health and food safety experts, including the Food and Drug Administration (FDA) and Centers for Disease Control (CDC), strongly urge consumers not to take this advice and stick with plain water.</p><p>Using such substances may pose further health dangers, and they're unnecessary to remove the most harmful residues from produce. <a href="https://www.healthline.com/health/chlorine-poisoning" target="_blank">Ingesting commercial cleaning chemicals</a> like bleach can be lethal and should never be used to clean food.</p><p>Furthermore, substances like lemon juice, vinegar, and produce washes have not been shown to be any more effective at cleaning produce than plain water — and may even leave additional deposits on food.</p><p>While some research has suggested that using neutral electrolyzed water or a baking soda bath can be even more effective at removing certain substances, the consensus continues to be that cool tap water is sufficient in most cases.</p><p><strong>Summary</strong></p><p><strong></strong>The best way to wash fresh produce before eating it is with cool water. Using other substances is largely unnecessary. Plus they're often not as effective as water and gentle friction. Commercial cleaners should never be used on food.</p>
How to Wash Fruits and Vegetables With Water<p>Washing fresh fruits and vegetables in cool water before eating them is a good practice when it comes to health hygiene and food safety.</p><p>Note that fresh produce should not be washed until right before you're ready to eat it. Washing fruits and vegetables before storing them may create an environment in which bacterial growth is more likely.</p><p>Before you begin washing fresh produce, <a href="https://www.healthline.com/health/how-long-should-you-wash-your-hands" target="_blank">wash your hands well</a> with soap and water. Be sure that any utensils, sinks, and surfaces you're using to prepare your produce are also thoroughly cleaned first.</p><p>Begin by cutting away any bruised or visibly rotten areas of fresh produce. If you're handling a fruit or vegetable that'll be peeled, such as an orange, wash it before peeling it to prevent any surface bacteria from entering the flesh.</p><p>The general methods to wash produce are as follows:</p><ul><li><strong>Firm produce.</strong> Fruits with firmer skins like apples, lemons, and pears, as well as <a href="https://www.healthline.com/nutrition/root-vegetables" target="_blank">root vegetables</a> like potatoes, carrots, and turnips, can benefit from being brushed with a clean, soft bristle to better remove residues from their pores.</li><li><strong>Leafy greens.</strong> Spinach, lettuce, Swiss chard, leeks, and cruciferous vegetables like Brussels sprouts and bok choy should have their outermost layer removed, then be submerged in a bowl of cool water, swished, drained, and rinsed with fresh water.</li><li><strong>Delicate produce.</strong> Berries, mushrooms, and other types of produce that are more likely to fall apart can be cleaned with a steady stream of water and gentle friction using your fingers to remove grit.</li></ul><p>Once you have thoroughly rinsed your produce, dry it using a clean paper or cloth towel. More fragile produce can be laid out on the towel and gently patted or rolled around to dry them without damaging them.</p><p>Before consuming your fruits and veggies, follow the simple steps above to minimize the amount of germs and substances that may be on them.</p><p><strong>Summary</strong></p><p><strong></strong>Most fresh fruits and veggies can gently be scrubbed under cold running water (using a clean soft brush for those with firmer skins) and then dried. It can help to soak, drain, and rinse produce that has more dirt-trapping layers.</p>
The Bottom Line<p>Practicing good food hygiene is an important health habit. Washing fresh produce helps minimize surface germs and residues that could make you sick.</p><p>Recent fears during the <a href="https://www.healthline.com/coronavirus" target="_blank">COVID-19 pandemic</a> have caused many people to wonder whether more aggressive washing methods, such as using soap or commercial cleaners on fresh produce, are better.</p><p>Health professionals agree that this isn't recommended or necessary — and could even be dangerous. Most fruits and vegetables can be sufficiently cleaned with cool water and light friction right before eating them.</p><p>Produce that has more layers and surface area can be more thoroughly washed by swishing it in a bowl of cool water to remove dirt particles.</p><p>Fresh fruits and vegetables offer a number of healthy nutrients and should continue to be eaten, as long as safe cleaning methods are practiced.</p>

From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in human history and culture. However, not all hybrids are as fantastic as the minotaur or as dependable as the mule; in fact, some of them cause human diseases.
When Looking Through a Microscope Isn’t Close Enough.<p>For the last few years, <a href="http://www.rokaslab.org/" target="_blank">our team at Vanderbilt University</a>, <a href="https://www.researchgate.net/lab/Gustavo-Goldman-Lab" target="_blank">Gustavo Goldman's team at São Paulo University in Brazil</a> and many other collaborators around the world have been collecting samples of fungi from patients infected with different species of <em>Aspergillus</em> molds. One of the species we are particularly interested in is <a href="https://doi.org/10.1006/rwgn.2001.0082" target="_blank"><em>Aspergillus nidulans</em>, a relatively common and generally harmless fungus</a>. Clinical laboratories typically identify the species of <em>Aspergillus</em> causing the infection by examining cultures of the fungi under the microscope. The problem with this approach is that very closely related species of <em>Aspergillus</em> tend to look very similar in their broad morphology or physical appearance when viewing them through a microscope.</p><p>Interested in examining the varying abilities of different <em>A. nidulans</em> strains to cause disease, we decided to analyze their total genetic content, or genomes. What we saw came as a total surprise. We had not collected <em>A. nidulans</em> but <em>Aspergillus latus</em>, a close relative of <em>A. nidulans</em> and, as we were to soon find out, <a href="https://doi.org/10.1016/j.cub.2020.04.071" target="_blank">a hybrid species that evolved through the fusion of the genomes</a> of two other <em>Aspergillus</em> species: <em>Aspergillus spinulosporus</em> and an unknown close relative of <em>Aspergillus quadrilineatus</em>. Thus, we realized not only that these patients harbored infections from an entirely different species than we thought they were, but also that this species was the first ever <em>Aspergillus</em> hybrid known to cause human infections.</p>
Several Different Fungal Hybrids Cause Human Disease.<p>Hybrid fungi that can cause infections in humans are well known to occur in several different lineages of single-celled fungi known as yeasts. Notable examples include multiple different species of <a href="https://doi.org/10.1002/yea.3242" target="_blank">yeast hybrids</a> that cause the human diseases <a href="https://rarediseases.info.nih.gov/diseases/6218/cryptococcosis" target="_blank">cryptococcosis</a> and <a href="https://www.cdc.gov/fungal/diseases/candidiasis/index.html" target="_blank">candidiasis</a>. Although pathogenic yeast hybrids are well known, our discovery that the <em>A. latus</em> pathogen is a hybrid is a first for molds that cause disease in humans.</p>
(Left) Candida yeasts live on parts of the human body. Imbalance of microbes on the body can allow these yeasts, some of which are hybrids, to grow and cause infection. (Right) Cryptococcus yeasts, including ones that are hybrids, can cause life-threatening infections in primarily immunocompromised people. Centers for Disease Control and Prevention<p><a href="https://doi.org/10.1371/journal.ppat.1008315" target="_blank">Why certain <em>Aspergillus</em> species are so deadly</a> while others are harmless remains unknown. This may in part be because <a href="https://doi.org/10.1016/j.fbr.2007.02.007" target="_blank">combinations of traits, rather than individual traits</a>, underlie organisms' ability to cause disease. So why then are hybrids frequently associated with human disease? Hybrids inherit genetic material from both parents, which may result in new combinations of traits. This may make them more similar to one parent in some of their characteristics, reflect both parents in others or may differ from both in the rest. It is precisely this mix and match of traits that hybrids have inherited from their parental species that <a href="https://www.nytimes.com/2010/09/14/science/14creatures.html" target="_blank">facilitates their evolutionary success</a>, including their ability to cause disease.</p>
