There have been widespread requires a world ban on the sale and consumption of untamed meat. Following the unfold of COVID in early 2020 (which is believed to have originated in bats), over 200 conservation organisations signed an open letter to the World Well being Group, urging a everlasting ban on all dwell wildlife markets and using wild animal merchandise in conventional medication.
The chance of illness spillover has been utilized by conservationists to legitimise arguments concerning the perceived must separate people from “wild” nature. Because the pandemic started, bans on wild animal consumption and commerce have been launched in a number of nations. Earlier than COVID, chicken flu and Ebola virus outbreaks additionally triggered bans on wildlife commerce and consumption in northern Vietnam and west Africa, respectively.
By proscribing contact between people and wild animals, such bans ought to in idea minimise the danger of future illness outbreaks. But these restrictions neglect their potential impression on rural and Indigenous teams, who typically rely on wild produce, notably meat, fish and bugs, as sources of dietary protein, fats and micronutrients.
Our earlier work has documented the significance of “wild meals” worldwide. And we proceed to search out proof that wild meat performs a crucial function in enhancing the diets of Indigenous teams, akin to Khasi communities in Meghalaya, northeast India. (To be clear, we’re not in any means selling the consumption of endangered animals, which is strictly prohibited around the globe.)

Understanding spillover occasions
For our newest evaluate, we extracted proof on “spillover occasions” (the transmission of a pathogen from an animal to a human) linked to wild meat consumption and associated practices (akin to looking and butchering), from obtainable scientific papers printed between 1940 and 2021. We discovered such proof to be restricted and infrequently of poor high quality.
In fact, there are dangers to consuming wild meat, however we have to higher perceive the precise consumption behaviour and practices that give rise to illness in order that we are able to devise extra focused approaches to mitigate future outbreaks.
There’s a danger that castigating wild meat harvesting practices in low-income settings fails to recognise the dangers of zoonotic ailments (ailments that may be transmitted from animals to people) related to western meals manufacturing and consumption practices.
We discovered that the best variety of spillover occasions reported within the scientific papers have been from the US, and these have been primarily linked to leisure looking. Whereas there are in all probability spatial biases in reporting (in some locations, ailments might go undiagnosed or be under-reported), elsewhere, analysis has instructed that solely 3% of rising infectious ailments from 1940 to 2004 have been attributable to wild meat, in contrast with 17% from standard agriculture and the meals trade. And 31% was linked to adjustments in land use, together with deforestation and habitat fragmentation.
We highlighted particular mechanisms that appeared to intensify spillover danger from wild meat harvesting and consumption, akin to involvement in looking or wild meat preparation, together with skinning and butchering. Cooking strategies additionally mattered, with the consumption of uncooked or undercooked meat typically talked about in studies.
In the direction of extra focused coverage responses
Our analysis suggests the necessity for extra nuanced approaches to guard an more and more globalised and interconnected world from the potential dangers of zoonotic spillover whereas not stigmatising the consumption practices of communities that depend on wild assets.
Understanding which animals harbour illness, understanding who’s most uncovered to high-risk animal species, understanding seasonal adjustments in publicity, and disseminating an understanding of protected and unsafe looking and cooking practices may very well be simpler than whole bans, and will end in higher adoption of protecting behaviour.
Merely banning wild meat consumption stigmatises shoppers and dangers pushing consumption practices underground, the place they develop into more durable to grasp and regulate.
With the speed of emergence of latest ailments accelerating, there’s a want for extra inclusive approaches, which steadiness the vulnerabilities of various, native communities and their continued want for wild meals sources, with the necessity to scale back the danger of future spillover related to consuming wild meat.
