Between 2010 and 2019, total imports of frog’s legs into the EU numbered 40.7 million kg, which equals to up to roughly 2 billion frogs. While Belgium is the main importer, France is the main consumer. These insights are part of a new study, published in the journal Nature Conservation, which found “inexplicable volatility” in the trade of frog legs and an extreme dependency of the EU on other countries to meet its demand.

Leading author Dr. Auliya of the Leibniz Institute for the Analysis of Biodiversity Change in Bonn, Germany, outlines the manifold uncertainties underlying this trade: “The international trade in frogs’ legs is a black box, whether it is the lack of species-specific trade data, which would be needed to ensure sustainability, or the large-scale mislabeling in trade and the challenges to identify species when it comes to processed, skinned and frozen frogs’ legs.”

Frogs have a central role in the ecosystem as insect predators – and where frogs disappear, the use of toxic pesticides increases. Hence, the frogs’ legs trade has direct consequences not only for the frogs themselves, but for biodiversity and ecosystem health as a whole. The extent to which pesticide residues in frogs’ legs are traded internationally remains unclear.

In the 1970s and 1980s, India and Bangladesh were the top suppliers of frogs’ legs to Europe, but when their wild frog populations collapsed, both countries banned exports. Since then, Indonesia has taken over as the largest supplier. In the Southeast Asian country, as now also in Turkey and Albania, large-legged frog species are dwindling in the wild, one after the other, causing a fatal domino effect for species conservation. This increasingly threatens frog populations in the supplier countries.

“The EU is by far the world’s largest importer of frogs’ legs, and large-legged species such as the crab-eating grass frog (Fejervarya cancrivora), the giant Javan frog (Limnonectes macrodon) and the East Asian bullfrog (Hoplobatrachus rugulosus) are in particular demand among supposed gourmets in Europe”, points out co-author Dr. Sandra Altherr, a biologist and wildlife trade expert of the Germany-based charity Pro Wildlife.

While commercial frog farms, like those operated in Viet Nam, may at first glance seem to be an alternative that can relieve the pressure from wild frog populations, ongoing restocking of frog farms with native species from the wild and, in the case of non-native species, such as the American bullfrog (Lithobates catesbeianus) the risk of escape, invasion and potential risk of disease spread, are serious risks for the environment.

The harvest of wild frog populations and species produced at commercial frog farms for the purpose of consumption also leaves disease control and hygiene measures by the wayside; additionally, the cross-border trade of species for consumption has led to genetic pollution and hybridization between species.

„During the course of this study, it became clear just how difficult it is to obtain concrete data on the current international trade in frogs’ legs. Specifically, relevant data are scattered across different unconnected databases,“ the researchers write in their paper.

In the course of their review, they were not able to find any published data out whether pesticide residues and other potentially toxic substances in (processed) frogs or their legs imported into the EU have been monitored. “This in itself is shocking and in view of the situation in exporting countries and the lack of transparency and management in the application of agrochemicals and veterinary medicinal substances within commercial farms, we strongly recommend that this monitoring become an urgent near-future task for importing countries,” they write.

“The complexity of issues underlying the frogs’ legs trade is not a priority policy item for the EU,” the authors conclude. They add that a listing of the most-affected frog species under CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora, would help to monitor trade and ensure its sustainability, and the EU as the main destination should take the lead on that.

Fraudulent microchip use and compliance issues found on controversial lion farms in the Free State, South Africa

Operating without valid permits and inconsistent record keeping were some of the irregularities found on commercial facilities for captive lions.

A number of serious management and compliance issues were revealed on lion farms in the Free State province, South Africa, by a joint team of researchers from MONITOR, Blood Lions, and World Animal Protection. Potentially fraudulent activities relating to the use of microchips, operating without valid permits, and incomplete, inconsistent, and unclear record keeping were some of the irregularities found on commercial facilities that keep and trade captive lions and other predators.

African lions are legally farmed in South Africa for commercial uses in interactive tourism activities, such as cub petting, voluntourism, or the “canned” hunting industry (where captive-bred lions are released into a confined space to be killed for sport). Other reasons include trade in live animals, or selling their body parts for the needs of traditional Asian Medicine.

All lions born and kept on commercial farms in South Africa should be registered with the provincial authority and fitted with a unique identification microchip, in order for each animal to be followed from birth to death through the system and to avoid the laundering of wild-caught and/or non-registered captive-bred lions.

A multinational team of researchers used permit data legally obtained from provincial authorities to summarise such uses of lions on farms in the Free State and found multiple instances of violation of national and provincial regulations.

It is known that the Free State province is at the heart of the commercial lion industry, with about a third of all lion facilities across the country located on its territory. These farms in the Free State predominantly breed, keep and euthanise lions, as well as trade with other provinces to supply “canned” hunting farms and tourism facilities. They also prepare lion body parts for export, such as taxidermy for trophies, and skeletons for the bone trade with Southeast Asia.

Data legally obtained from the Free State Department of Small Business Development, Tourism and Environmental Affairs show hundreds of reused microchip numbers across permits for keeping, euthanising and transporting captive lions, indicating potential non-compliance with national and provincial regulations.

During a four-year period (2017-2020), more than 500 unique microchips (11% of the total microchip numbers) could not be followed through the system. For euthanasia permits, the number of potentially fraudulently used microchip numbers of lions was as many as 15%, and in some cases a microchip number had been reused up to four times.

This raises serious concerns that lion farm owners may deliberately be reusing microchip numbers to launder wild-caught and/or unregistered captive-bred lions.

“Although some of these inconsistencies may have legitimate explanations, the number of times microchip numbers were reused is worrisome and requires further investigation by the authorities”, states Dr Sarah Heinrich of MONITOR, one of the researchers behind the study, which was published in the journal Nature Conservation.

The laundering of lions and/or other predators through the fraudulent use of microchips has implications beyond South Africa’s borders, in particular, in the trade in lion bones for traditional medicine, where bones, claws, skeletons, and skulls are exported to Southeast Asia. “Looking at live lion exports through the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), it is unclear what happens to these animals once they arrive at their international destinations. It is possible that some of these live exports circumvent the zero CITES lion bone export quota and are eventually euthanised at their import destinations to feed the persisting demand for lion bones”, said Dr Jennah Green of World Animal Protection.

CITES is the main regulatory mechanism governing the commercial international trade in certain wildlife species, including lions, their body parts, and derivatives. Under CITES, (African) lions are listed in Appendix II. A screenshot from Speciesplus.net, taken 31 January 2023.

Lions that were euthanised in the Free State in 2019 and 2020, during a CITES zero export quota for lion bones, most likely became part of a growing and largely unregulated stockpile of lion bones that exists in South Africa, which warrants further investigation.

Ensuring regulatory compliance in all areas of the commercial captive lion industry is more important now than ever. In 2021, Minister Barbara Creecy of the Department of Forestry, Fisheries and the Environment (DEFE), stated that the South African government intends to effectively end the commercial captive lion industry through a mandatory phase-out, which eventually was changed to a voluntary scheme.

In its current state, the lion farming industry is governed by a patchwork of contrasting legislation across multiple provincial and national authorities, with disparities and legal loopholes, which create opportunity for harmful and fraudulent activity.

“Our research highlights many areas of grave concern and these issues need the urgent attention of the Minister and the DFFE, as well as the nine provincial nature conservation authorities, to put stricter enforcement of the TOPS Regulations in place”, concludes Dr Louise de Waal, Director of Blood Lions.

Illegal trade with terrestrial vertebrates in markets and households of Laos

Extensive surveys on wildlife markets and households in the Khammouane Province of Laos showed overlaps between the most traded species at wildlife markets and those of highest conservation importance.

It’s not a surprise to anyone that numerous vertebrate species are being sold at different wildlife markets, but at the moment there is still no comprehensive understanding of how much people are involved in those actions in Laos (Lao PDR), nor what the impact on local wildlife populations really is.

The majority of Laotians live in rural areas and their income largely depends on wildlife. Since wildlife products are used as one of the major food sources, numerous species of terrestrial vertebrates are currently being offered at local markets.

Across the tropical regions, mammals and birds have been vanishing, with recent models estimating up to 83% decline by 2050. Furthermore, wild-caught reptiles have been reported from Southeast Asian wildlife markets for over 20 years, with Laos occupying the position of a very popular source.

Due to the large number of native endemic species, Lao PDR should assume the responsibility to introduce conservation measures to keep control over the predicted population declines. At the moment, the regulations on wildlife use and trade in Laos are mostly based on the Lao Wildlife and Aquatic Law, which, however, largely disregards international statuses of the species and other biological factors.

Stricter and reinforced legislation is needed in the fields related to wildlife trade and consumption, since such practices are not only causing biodiversity loss, but also suggested to pose a great threat of wildlife-associated emergence of zoonotic parasites and pathogens to humans. As an immediate example, the outbreak of the Coronavirus (COVID-19) is primarily considered to be a consequence of human consumption of wild animals.

An international group of students and scientists, led by Professor Dr. Thomas Ziegler at the University of Cologne and the Cologne Zoo (Germany), has conducted a number of extensive surveys on wildlife markets (66 observational surveys at 15 trade hubs) and households (63 households at 14 sites) in the Khammouane Province of Laos. The key question of the survey was: “Which species are traded and to what extent?” The results of the study are published in the open-access journal Nature Conservation.

The surveys showed overlaps between the most traded species at wildlife markets and those of highest conservation importance.

As for the households, approximately 90% of the surveyed respondents confirmed the use of wildlife. For the majority of the population, wildlife harvesting was found to be important for their livelihood and trapping activities were mostly aimed at self-consumption / subsistence. The reason for this could be explained by the prices of domesticated meat, which can be three times as higher as those of wildlife products.

The demand for the species on the wildlife market remained the same over time, according to the opinions of 84,1% of respondents, while the availability of wild meats was reported to have decreased, due to increasing price.

“We recommend local authorities to assess the markets within the province capital Thakhek in particular, as they showed the highest quantity of wild meats. The markets at Namdik and Ban Kok turned out to be very active trade hubs for wildlife as well, regardless of the vertebrate group. The loss of certain species may cause a cascade of unforeseeable effects in the ecosystems. Therefore, the biodiversity of tropical Southeast Asian countries like Lao PDR must be protected,”
shares Dr. Thomas Ziegler.

To help the local population to avoid the crisis related to the change of activity and growing unemployment, scientists propose to introduce new activities in the region.

“Eco-tourism presents a great opportunity to combine conservation efforts and an alternative source of income. Former hunters with excellent knowledge of the forest and wildlife habitats can serve as professional wildlife tour guides or their involvement in the Village Forest Protection Group could help to protect natural resources in Laos”,
suggests Dr. Thomas Ziegler.
