Wildlife Consumption Research Articles

Motivations for the use and consumption of wildlife products.

The dominant approach to combating the illegal wildlife trade has traditionally been to restrict the supply of wildlife products. Yet conservationists increasingly recognize the importance of implementing demand-side interventions that target the end consumers in the trade chain. Their aim is to curb the consumption of wildlife or shift consumption to more sustainable alternatives. However, there are still considerable knowledge gaps in understanding of the diversity of consumer motivations in the context of illegal wildlife trade, which includes hundreds of thousands of species, different uses, and diverse contexts. Based on consultation with multiple experts from a diversity of backgrounds, nationalities, and focal taxa, we developed a typology of common motivations held by wildlife consumers that can be used to inform conservation interventions. We identified 5 main motivational categories for wildlife use: experiential, social, functional, financial, and spiritual, each containing subcategories. This framework is intended to facilitate the segmentation of consumers based on psychographics and allow the tailoring of interventions-whether behavior change campaigns, enforcement efforts, or incentive programs-to the specific context in which they will be used. Underlining the importance of consumer research and collaborating with local actors is an important step toward promoting a more systematic approach to the design of demand reduction interventions.

Changes of China's regulatory regime on commercial artificial breeding of terrestrial wildlife in time of COVID-19 outbreak and impacts on the future

The basic attitude of Chinese law towards wildlife resources is differentiated protection plus rational utilizations. Artificial breeding of terrestrial wildlife was a big business and a way to alleviate poverty, but also raised concerns over wildlife conservation and public health. China's complete ban on the consumption of terrestrial wildlife, whether wild-sourced or artificially bred, was a drastic change of China's legal regime on wildlife conservation and commercial artificial breeding. This change will have impacts on the drafting of a new Biosafety Law and the revision and enforcement of the Wildlife Protection Law, the Husbandry law, the Fisheries Law, and the Animal Epidemic Prevention Law.

Understanding China's wildlife markets: Trade and tradition in an age of pandemic.

Environmentalists have long been concerned about the rate at which China is consuming and trading in threatened and endangered wildlife. The recent COVID-19 global pandemic has made wildlife consumption an issue that concerns everyone around the world. Formerly obscure practices like wet markets and commodities like pangolin scales or bear bile have gained international notoriety. Along with that attention has come increasing politicization and ideological polarization. Beyond the global fight against the pandemic, there has been another global struggle over the meaning and origin of the disease, as evidenced by the spread of terms like “Wuhan Flu” and “bat soup.” What has become obscured by the news cycle struggling to keep up with the rapid spread of the virus and the political sound and fury surrounding it is any meaningful understanding of China’s wildlife consumption and trade. Deeply ingrained in Chinese culture and history, the wildlife trade is not going away anytime soon. Despite a national ban, already wet markets are returning across China. Addressing the wildlife trade in China, we argue, requires first understanding it.

Targeted values: The relevance of classical Chinese philosophy for illegal wildlife demand reduction campaigns

Abstract The illegal wildlife trade is a global conservation priority, prompting a rise in interventions aimed at reducing the demand for wildlife products. Research shows that designing campaigns to target the values held by a specific audience is an effective way to alter their behaviour. However, many demand reduction campaigns are grounded in the perspective of Western morality. This is problematic when the recipients of these campaigns frequently reside in East Asia, where they are exposed to the historical and cultural praxis of Confucianism and Daoism. This paper examines some of the central concepts of classical Chinese philosophy to see how they could be used by practitioners to design effective behaviour change campaigns in the future. Acknowledging that the East Asian cultural sphere has a long history of consumptive wildlife use, reflecting an instrumentalist and anthropocentric approach to wildlife, we still find potential for appealing to a relational ethic. There is a fundamental metaphysics that all of nature is unified, interconnected and interpenetrating. Qi is the vital force of the universe that links inorganic, organic and human life‐forms, creating the basis for a profound reciprocity between humans and the natural world. We also consider some of the key virtues in Chinese philosophy, and how they could be interpreted through the lens of demand reduction for illegal wildlife products. This includes li, ritual propriety, and ren, the inner moral force which keeps us in balance. Finally, we cover influential scriptures, identifying many historical verses that are relevant to modern conservationists.

The seven sins of hunting tourism

In a review of situational pressures on tourists, we identify seven sins or risk zones that induce moral disengagement and allow for behaviour that would be considered unethical by the same people when not on holiday. The context of hunting tourism reveals the following sins act cumulatively on the hunting tourist: “The Pay Effect”, “The Tourist Bubble”, “Last Chance Tourism”, “The Bucket List”, “When in Rome”, “The False Display”, and “The Saviour”. Identifying these sins and the way hunting tourists draw from them to neutralize eco-guilt are argued to be a first step on the call to set standards and practices within consumptive wildlife tourism consistent with the Precautionary Principle in tourism planning.

Wildlife consumption of neonicotinoid-treated seeds at simulated seed spills

The most likely route of exposure to high concentrations of neonicotinoids capable of producing lethal or sublethal effects in birds and mammals is consumption of treated seeds. We placed trail cameras at simulated seed spills to document wildlife consuming treated seeds during the spring planting season. We simulated 4 types of spills, corn treated with 2 concentrations of clothiandin (0.50 or 0.25 mg/seed), corn treated with thiamethoxam (0.25 mg/seed), and soybean treated with imidacloprid (0.15 mg/seed). We documented 16 species of birds and 14 species of mammals eating neonicotinoid-treated seeds at spills. Of these, we quantified consumption of treated seeds by 12 species of birds and 13 species of mammals. Birds and mammals did not consume enough seeds to exceed published LD50s in related taxa, but most species did consume enough seeds to reach or exceed thresholds for sublethal effects based on currently available studies. Birds and mammals did not increase the amount of seeds consumed over time, as would be expected if responsive to the concentration of neonicotinoids on seeds, but more birds and mammals consumed seeds over time, as a proportion of the number at spills each day. More birds also consumed seeds after a soaking rain event, which likely reduced the amount of treatment on the seeds. Importantly, wildlife are consuming seeds while neonicotinoids are still concentrated on seeds. Our findings indicate that previously held assumptions about the safety of neonicotinoid seed treatments for vertebrate wildlife need to be revisited.

Animal-based food systems are unsafe: severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) fosters the debate on meat consumption.

The current pandemic restarts a debate on permanently banning wildlife consumption in an effort to prevent further public health threats. In this commentary, we offer two ideas to enhance the discussion on foodborne zoonotic diseases in food systems. First, we focus on the probable consequences that the loss of access to wildlife could cause to the status of food and nutrition security of many people in developing countries that rely on bushmeat to subsist. Second, we argue that all animal-based food systems, especially the ones based on intensive husbandry, present food safety threats. To ban the access to bushmeat without a rational analysis of all human meat production and consumption in the global animal-based food system will not help us to prevent future outbreaks.

Trends in illegal wildlife trade: Analyzing personal baggage seizure data in the Pacific Northwest.

The illegal import of wildlife and wildlife products is a growing concern, and the U.S. is one of the world’s leading countries in the consumption and transit of illegal wildlife and their derivatives. Yet, few U.S. studies have analyzed the illegal wildlife trade (IWT) on a national or local scale. Moreover, to our knowledge, no studies have specifically examined the trends associated with IWT moving through personal baggage. This work aimed to better understand the magnitude of illegal wildlife importation into U.S. ports of entry by determining trends associated with illegal wildlife products from personal baggage seizures, using the Pacific Northwest (PNW) as a specific case study. To identify the most influential factors determining the numbers and types of personal baggage seizures into PNW, we analyzed 1,731 records between 1999 and 2016 from the Fish and Wildlife Service’s (FWS) Law Enforcement Management Information System (LEMIS) database. We found five significant contributors: taxonomic classification of wildlife, categorical import date, wildlife product, source region, and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) status. While wildlife seizures across taxonomic categories have generally decreased in the PNW since 2008, other findings provide a reason for concern. More specifically, mammals were identified as the largest animal group of seized wildlife, and temporal trends indicate increases in seizures for this and several other taxonomic groups. Many of the seizures originated from overseas, with East Asia serving as the largest source. Our PNW case study can be a model for how large-scale geographical seizure data can be used to inform about the major factors that have historically and presently contribute to IWT, with conservation implications globally.

Considering Domestic and International Frameworks for Analyzing China’s Potential Legal Liability in the Aftermath of COVID-19

The COVID-19 pandemic has imposed a human and economic cost on the world that was virtually unimaginable only a few months ago. Credible investigative sources agree with virtual unanimity that COVID-19 emerged from Wuhan in China, either as a result of human wildlife consumption at wet markets or from a laboratory that studies diseases in bats. China has long been aware of the risks that both scenarios presented. Even more disturbingly, however, China may have hid valuable information about COVID-19 that could have significantly improved the international community’s ability to respond to, and fight, the pandemic. China’s apparent obfuscation, along with the alleged failures of other groups such as the World Health Organization, has arguably resulted in trillions of dollars in liabilities, millions of sicknesses, and hundreds of thousands of lost lives—with those numbers mounting daily. The emergence of COVID-19 within China and the Chinese government’s failure to promptly and transparently provide needed information to the international community raises the question whether the Chinese government and/or its officials could be held civilly or criminally liable under international law or U.S. domestic law. While China arguably violated numerous international conventions and obligations, and while there would certainly be liability according to U.S. common law principles if this scenario involved a private party, the reality is that neither is likely adequate to impose liability on China under the current state of the law, meaning the international community would need to create a new framework for imposing international legal liability—something the U.S. should be very weary of—or the U.S. would need to revoke China’s sovereign immunity, something that lawmakers are currently considering. Either way, the COVID-19 outbreak demands serious consideration of how the legal system could—and whether it should—be updated to account for the current crisis and any future pandemics. This article discusses the Chinese government’s potential violations of existing international law and international norms, as well as potential theories of civil and criminal liability arising from the damages caused by the COVID-19 pandemic. Part I provides an introduction. Part II provides a background of key facts as currently understood and lays out the role that the Chinese government apparently played in enabling COVID-19 and failing to contain its global spread. Part III discusses the manner in which China may have run afoul of various treaties and civil tort principles, as well as the difficulties with imposing civil liability for these violations. Part IV articulates theories about how traditional criminal liability might apply to China and why international criminal law is generally too limited in scope to impose liability. Finally, Part V suggests a potential framework for ensuring accountability for the COVID-19 outbreak and any future pandemics. This article concludes that although litigation—and civil and criminal liability both at the domestic and international level—can be effective tools in the diplomatic arsenal of nations, practical realities and the current legal framework limit China’s potential liability arising from the COVID-19 crisis. Nevertheless, this paper could serve as a starting point for discussing whether a new framework is necessary.

An Assessment of Wildlife Use by Northern Laos Nationals.

Simple SummaryAlthough unsustainable wildlife consumption is a leading threat to biodiversity in Southeast Asia, there is still a notable lack of research around the issue, particularly into which animals may be “on the horizon” of impending conservation concern. Using semistructured interviews, we investigated the consumption of wildlife in northern Laos, with a focus on the use of wildlife for medicinal purposes. Bear bile was the most popular product, but serow bile was second in popularity and used for similar ailments. In light of these results, and considering the vulnerability of both bear and serow populations in the wild, greater concern needs to be taken to reduce demand for these products, before this demand becomes a significant conservation challenge. Unsustainable wildlife trade is a well-publicized area of international concern in Laos. Historically rich in both ethnic and biological diversity, Laos has emerged in recent years as a nexus for cross-border trade in floral and faunal wildlife, including endangered and threatened species. However, there has been little sustained research into the scale and scope of consumption of wildlife by Laos nationals themselves. Here, we conducted 100 semistructured interviews to gain a snapshot of consumption of wildlife in northern Laos, where international and in some cases illegal wildlife trade is known to occur. We found that although bear bile for medicine was the most common product consumed, individuals also used a variety of other products, including animals considered endangered by the International Union for Conservation of Nature IUCN. The majority of animals we found consumed are classified as “Vulnerable” or “Least Threatened” by the IUCN; however, sufficient demand for a species can cause increased, rapid decline in the species’ population and significantly increase the challenge of conserving them. These results therefore illuminate where conservation priorities should shift towards, so that stable-yet-consumed species do not mirror the fate of highly trafficked animals.

Wildlife consumption ban is insufficient

On 24 February, China's top legislature comprehensively prohibited the consumption of terrestrial wildlife to protect public health (1). The ban was enacted in response to the outbreak of coronavirus disease 2019 (COVID-19), which is considered to be linked to wildlife consumption (2). However, a total ban on the consumption of terrestrial wildlife alone is not enough to effectively protect public health from wildlife-associated diseases.

Rethinking game consumption in tourism: a case of the 2019 novel coronavirus pneumonia outbreak in China

ABSTRACT This opinion piece highlights a lethal connection between novel coronavirus pneumonia (NCP) and wildlife consumption in tourism. While NCP continues to make headlines in the mainstream media, little academic research has considered this illness, especially through the lens of food neophilic tourism. Yet this research stream requires attention, particularly because food is a key motivational factor behind tourists’ travel and destination choices. In the case of food neophilic tourism, visitors directly consume wildlife and other exotic cuisine. Unfortunately, this novelty-seeking behavior may pose health risks; wild and exotic animals can carry deadly viruses that have been found to trigger global health epidemics such as SARS, H1N1, bird flu, and NCP. Despite international government agencies’ legislative efforts to control wild and exotic animal consumption, demand from food neophilic tourists continues to increase. This paper initiates a dialogue urging tourism scholars to study food tourism and offers practical and theoretical insight to contextualize this perennial and pertinent phenomenon.

Potential Factors Influencing Repeated SARS Outbreaks in China.

Within last 17 years two widespread epidemics of severe acute respiratory syndrome (SARS) occurred in China, which were caused by related coronaviruses (CoVs): SARS-CoV and SARS-CoV-2. Although the origin(s) of these viruses are still unknown and their occurrences in nature are mysterious, some general patterns of their pathogenesis and epidemics are noticeable. Both viruses utilize the same receptor—angiotensin-converting enzyme 2 (ACE2)—for invading human bodies. Both epidemics occurred in cold dry winter seasons celebrated with major holidays, and started in regions where dietary consumption of wildlife is a fashion. Thus, if bats were the natural hosts of SARS-CoVs, cold temperature and low humidity in these times might provide conducive environmental conditions for prolonged viral survival in these regions concentrated with bats. The widespread existence of these bat-carried or -released viruses might have an easier time in breaking through human defenses when harsh winter makes human bodies more vulnerable. Once succeeding in making some initial human infections, spreading of the disease was made convenient with increased social gathering and holiday travel. These natural and social factors influenced the general progression and trajectory of the SARS epidemiology. However, some unique factors might also contribute to the origination of SARS in Wuhan. These factors are discussed in different scenarios in order to promote more research for achieving final validation.

Public perception of wildlife consumption and trade during the COVID-19 outbreak

The COVID-19 pandemic has drawn great attention to the potential public health risks associated with the consumption and trade of wildlife To inform legislative revision and policy changes, we conducted a web-based survey of the general public, attracting 74,040 responses The survey examined public support for revising legislation and policy related to wildlife consumption and trade management The results and analysis revealed: (1) The overwhelming majority ( 90%) of constituents supported more stringent policy and legislation on wildlife consumption, trade, and commercial exhibitions (2) The consumption of wildlife is likely to fall due to COVID-19 (3) People that engaged either directly or indirectly in wildlife-related industries showed less support for more stringent policy and legislation on wildlife consumption and trade Based on these results and concerns for public health security, a ban on wildlife consumption and revised legislation by the Standing Committee of the National People's Congress was widely supported, particularly among educated, urban respondents

Understanding and changing wildlife consumption behavior from a multidisciplinary perspective

Escalating global demand for wildlife products and consequential illegal wildlife trade has become one of the major threats to biodiversity conservation In the recent COVID-19 pandemic, growing public health risks of wildlife trade and consumption have triggered widespread public concern In this review, we adopt a multidisciplinary perspective, including sociology, psychology, behavioral science and other disciplines, to understand the motivations for wildlife consumption in China, and to propose scientifically guided behavioral change countermeasures The current state of wildlife consumption in China reveals certain functional, social, experiential and other non-essential needs of wildlife as major drivers of consumption, which are affected by a host of complex factors Based on our understanding of the drivers of demand, we suggest using behavioral change frameworks, and a variety of behavioral change methods, including education, social influence, regulation and nudging, to effectively influence and change wildlife consumption behavior For effective implementation of behavioral change strategies, collaboration needs to be strengthened, both among and across diverse disciplines, actors and scales of interest

Long-range transport of legacy organic pollutants affects alpine fish eaten by ospreys in western Canada

Persistent organic pollutants (POPs) contaminate pristine, alpine environments through long-range transport in the atmosphere and glacier trapping. To study variation in POPs levels in western Canada, we measured levels in the prey (fish) of osprey (Pandion haliaetus) during 1999–2004, and compared those to levels in eggs and chicks. Values in fish muscle (representing human consumption) correlated with whole carcasses (wildlife consumption) for all POPs, except toxaphene, allowing us to pool data. Biomagnification factors for osprey eggs were much higher than published values from Oregon, reflecting differences in local diet. We factored baseline-corrected food chain variation by using amino acid-specific analysis of osprey eggs, illustrating how top predators (ospreys) can indicate both ecosystem-wide baselines and contamination. Given that our biomagnification factors were so different from those for the same species from a nearby site, we argue that trophic magnification factors derived from baseline-corrected δ15N are likely a more accurate method for estimating contamination. Dichlorodiphenyltrichloroethane (ΣDDT) concentrations were greatest in rainbow trout from a small lake at 1800 m, and those levels exceeded wildlife and human health guidelines. Indeed, once sites with known agricultural inputs were eliminated, elevation, percent lipids and baseline-corrected δ15N (from amino acid specific isotope values) best predicted ΣDDT. Baseline-corrected, but not bulk, δ15N was the main predictor of polychlorinated biphenyls (ΣPCB). Total toxaphene was consistently the major contaminant after ΣPCB and ΣDDT in osprey eggs, and was present in many fish samples. We concluded that toxaphene arrived from long range deposition due to high proportions of Parlar 40–50 congeners. The only exception was Paul Lake, where toxaphene was used as a piscicide, with a high concentrations of the Hex-Sed and Hep-Sed congeners at that site. We conclude that long-range transport and trophic position, not melting glaciers, were important determinants of some legacy POPs in fish and wildlife in alpine Canada.

Review of ecological mercury and arsenic bioaccumulation within historical gold mining districts of Nova Scotia

Gold mining in Nova Scotia dates back to the mid-1800s. Historical industrial practices generated over 3 000 000 tonnes of finely ground mine wastes (tailings), the majority of which were deposited into lakes, streams, wetlands, and low-lying areas close to the mill sites. These legacy tailings typically contain high concentrations of mercury (Hg) and arsenic (As) and continue to impact downstream environments to this day. The objective of this review is to critically examine and summarize existing knowledge on the transfer and bioaccumulation of Hg and As in aquatic and terrestrial organisms exposed to legacy gold mine tailings in Nova Scotia. This review reveals that as of mid-2019, 23 previous studies have been completed on this subject. Several of these studies were based on small sample sizes, or had other limitations, such as missing identification of biological species. Despite these limitations, the data in these publications clearly indicate that both Hg and As from abandoned gold mine sites in Nova Scotia are bioaccumulating in plants, fungi, freshwater and terrestrial invertebrates, marine mollusks, amphibians, fish, and mammals. In many cases, concentrations of MeHg exceed Canadian Council of Ministers of the Environment safety guideline values for consumption of wildlife; however, no guideline values are in place for either total Hg or As. No studies were found examining tailings-related Hg or As accumulation in lichen, reptiles, birds, or large mammals. This review concludes that further research on bioaccumulation and biomagnification of tailings-related Hg and As is needed to understand the overall impact of historical tailings on the aquatic and terrestrial ecosystems and species of Nova Scotia. More detailed studies are vital for guiding risk-management decisions and future land-use practices for these contaminated sites.

Toward a quantification of risks at the nexus of conservation and health: The case of bushmeat markets in Lao PDR

Trade of bushmeat and other wildlife for human consumption presents a unique set of challenges to policy-makers who are confronted with multiple trade-offs between conservation, food security, food safety, culture and tradition. In the face of these complex issues, risk assessments supported by quantitative information would facilitate evidence-based decision making.We propose a conceptual model for disease transmission risk analysis, inclusive of these multiple other facets. To quantify several processes included in this conceptual model we conducted questionnaire surveys with wildlife consumers and vendors in semi-urban centers in Lao People's Democratic Republic (Lao PDR, Laos) and direct observations of consumer behaviors. Direct observation of market stalls indicated an estimated average of 10 kg bushmeat biomass per stall per hour. The socio-demographic data suggested that consumption of bushmeat in urban areas was not for subsistence but rather driven by dietary preference and tradition. Consumer behavioral observations indicated that each animal receives an average of 7 contacts per hour. We provide other key parameters to estimate the risk of disease transmission from bushmeat consumption and illustrate their use in assessing the total public health and socio-economic impact of bushmeat consumption.Pursuing integrative approaches to the study of bushmeat consumption is essential to develop effective and balanced policies that support conservation, public health, and rural development goals.

Serological and molecular detection of Toxoplasma gondii in terrestrial and marine wildlife harvested for food in Nunavik, Canada

BackgroundToxoplasma gondii, a zoonotic protozoan parasite, infects mammals and birds worldwide. Infection in humans is often asymptomatic, though illnesses can occur in immunocompromised hosts and the fetuses of susceptible women infected during pregnancy. In Nunavik, Canada, 60% of the Inuit population has measurable antibodies against T. gondii. Handling and consumption of wildlife have been identified as risk factors for exposure. Serological evidence of exposure has been reported for wildlife in Nunavik; however, T. gondii has not been detected in wildlife tissues commonly consumed by Inuit.MethodsWe used a magnetic capture DNA extraction and real-time PCR protocol to extract and amplify T. gondii DNA from large quantities of tissues (up to 100 g) of 441 individual animals in Nunavik: 166 ptarmigan (Lagopus lagopus), 156 geese (Branta canadensis and Chen caerulescens), 61 ringed seals (Pusa hispida), 31 caribou (Rangifer tarandus) and 27 walruses (Odobenus rosmarus).ResultsDNA from T. gondii was detected in 9% (95% CI: 3–15%) of geese from four communities in western and southern Nunavik, but DNA was not detected in other wildlife species including 20% (95% CI: 12–31%) of ringed seals and 26% (95% CI: 14–43%) of caribou positive on a commercial modified agglutination test (MAT) using thawed heart muscle juice. In geese, tissue parasite burden was highest in heart, followed by brain, breast muscle, liver and gizzard. Serological results did not correlate well with tissue infection status for any wildlife species.ConclusionsTo our knowledge, this is the first report on the detection, quantification, and characterization of DNA of T. gondii (clonal lineage II in one goose) from wildlife harvested for food in Nunavik, which supports the hypothesis that migratory geese can carry T. gondii into Nunavik where feline definitive hosts are rare. This study suggests that direct detection methods may be useful for detection of T. gondii in wildlife harvested for human consumption and provides data needed for a quantitative exposure assessment that will determine the risk of T. gondii exposure for Inuit who harvest and consume geese in Nunavik.

Can nature deliver on the sustainable development goals?

The increasing availability of data and improved analytical techniques now enable better understanding of where environmental conditions and human health are tightly linked, and where investing in nature can deliver net benefits for people—especially with respect to the most vulnerable populations in developing countries. These advances bring more opportunities for interventions that can advance multiple SDGs at once. We have harmonised a suite of global datasets to explore the essential nexus of forests, poverty, and human health, an overlap of SDG numbers 1, 2, 3, 6, and 15. Our study combined demographic and health surveys for 297 112 children in 35 developing countries with data describing the local environmental conditions for each child (appendix).4 This allowed us to estimate the effect forests might have in supporting human health, while controlling for the influence of important socio-economic differences.4 We extended this work to look at how forests affect three childhood health concerns of global significance for the world's poorest people: stunting, anaemia, and diarrhoeal disease.
