Consumption of Domestic Cat in Madagascar: Frequency,Purpose, and Health Implications

ABSTRACT

The domestic cat Felis catus has a long history of interaction with humans, and is found throughout the world as a household pet and a feral animal. Despite people's often sentimental association with cats, cat meat is sometimes consumed by them; this practice can have important implications for public health. In Madagascar, a least developed country that has experienced recent political instability, cat consumption is known to occur, but remains poorly understood. To improve our understanding of cat consumption practices in Madagascar we interviewed 512 respondents in five towns. We used semi-structured interviews to: 1) clarify the preference for, and prevalence, correlates, and timing of, cat consumption; 2) describe methods used to procure cats for consumption; 3) identify motives for consuming cat meat; and, 4) evaluate to what extent patterns of cat-meat consumption are influenced by taboos. We found that, although cat was not a preferred source of meat, many (34%) Malagasy respondents had consumed cat meat before, with most (54%) of these indicating such consumption occurred in the last decade. We did not detect a link between consumption of cat meat and recent access to meat (a proxy for food security). Cat meat was almost never purchased, but rather was obtained when the owners consumed their own pet cat, as a gift, or by hunting feral cats. Cat meat was usually consumed in smaller towns following cat–human conflict such as attacks on chickens, but in the large capital city, cat meat was procured primarily from road-killed individuals. These results suggest cat-meat consumption is typically an opportunistic means to obtain inexpensive meat, rather than principally serving as a response to economic hardship. These results further suggest cat handling and consumption may present a potential pathway for transmission of several diseases, including toxoplasmosis, that may warrant heightened public health efforts.     

Interactive impacts of by-catch take and elite consumption of illegal wildlife

Harvesting, consumption and trade of forest meat are key causes of biodiversity loss. Successful mitigation programs are proving difficult to design, in part because anthropogenic pressures are treated as internationally uniform. Despite illegal hunting being a key conservation issue in the Pacific Islands, there is a paucity of research. Here, we examine the dynamics of hunting of birds and determine how these contribute to biodiversity loss on the islands of Samoa. We focus on the interactive effects of hunting on two key seed dispersing bird species: the Pacific pigeon (Ducula pacifica) and the critically endangered Manumea or tooth-billed pigeon (Didunculus strigiristris). We interviewed hunters, vendors and consumers and analyzed household consumption. Results suggest that over 22,000 pigeons were consumed per year and this is by primarily the richest people across the country. Indeed, the wealthiest 10% of households consumed 43% of all wild pigeon meat, and the wealthiest 40% of households consumed 80% of all pigeons. The Manumea was shot by 33% (n = 30) of the surveyed hunters while pursuing the Pacific pigeon. Results raise serious conservation concerns, as pigeon hunting is likely to be a key factor contributing to the decline of the Manumea and critical forest seed dispersers in general. Our results show that wild meat consumption can lead to non-targeted pressure on bycatch species. Wild meat harvesting and consumption is a key issue leading to species declines and extinctions in the tropics. It is critical that this issue receives the appropriate attention and is addressed in the Pacific if species and forests are to be maintained.     

Analysis of patterns of bushmeat consumption reveals extensive exploitation of protected species in eastern Madagascar

Understanding the patterns of wild meat consumption from tropical forests is important for designing approaches to address this major threat to biodiversity and mitigate potential pathways for transmission of emerging diseases. Bushmeat consumption has been particularly poorly studied in Madagascar, one of the world's hottest biodiversity hotspots. Studying bushmeat consumption is challenging as many species are protected and researchers must consider the incentives faced by informants. Using interviews with 1154 households in 12 communes in eastern Madagascar, as well as local monitoring data, we investigated the importance of socio-economic variables, taste preference and traditional taboos on consumption of 50 wild and domestic species. The majority of meals contain no animal protein. However, respondents consume a wide range of wild species and 95% of respondents have eaten at least one protected species (and nearly 45% have eaten more than 10). The rural/urban divide and wealth are important predictors of bushmeat consumption, but the magnitude and direction of the effect varies between species. Bushmeat species are not preferred and are considered inferior to fish and domestic animals. Taboos have provided protection to some species, particularly the Endangered Indri, but we present evidence that this taboo is rapidly eroding. By considering a variety of potential influences on consumption in a single study we have improved understanding of who is eating bushmeat and why. Evidence that bushmeat species are not generally preferred meats suggest that projects which increase the availability of domestic meat and fish may have success at reducing demand. We also suggest that enforcement of existing wildlife and firearm laws should be a priority, particularly in areas undergoing rapid social change. The issue of hunting as an important threat to biodiversity in Madagascar is only now being fully recognised. Urgent action is required to ensure that heavily hunted species are adequately protected.     

Public health significance of zoonotic bacterial pathogens from bushmeat sold in urban markets of Gabon, Central Africa

Wild animal meat represents an important source of protein for many people in central Africa. Also known as bushmeat, this meat commodity is derived from wild animals hunted under uncontrolled conditions, transported to distant markets under rudimentary or no hygienic methods, and often eviscerated >24 hr after death. Considering the plausible role of wildlife as a reservoir for bacterial zoonotic pathogens, bushmeat may be an important public health risk in Central Africa. This cross-sectional survey served to evaluate the presence of Campylobacter, Salmonella, and Shigella in the muscle tissue of 128 wild animal carcasses from several hunted wildlife species (guenons [Cercopithecus spp.], collared mangabeys [Cercocebus torquatus], gray-cheeked mangabeys [Lophocebus albigena], African crested porcupines [Atherurus africanus], duikers [Cephalophus spp.], and red river hogs [Potamocherus porcus]) sold in two markets of Port-Gentil, Gabon, in July and August 2010. Salmonella was detected from one carcass; no Campylobacter or Shigella was detected. If Campylobacter and Shigella were present, the maximum expected prevalence was estimated at 6% and 1%, respectively. In light of such very low apparent muscle contamination levels, bushmeat likely does not represent a health risk per se with respect to Campylobacter, Salmonella, or Shigella. However, because carcass evisceration and skinning can take place within households prior to consumption, consumers should follow strict hygiene and food safety practices to avoid potential health hazards associated with the handling, preparation, or consumption of bushmeat.     

Attractants for wild pigs: current use,availability, needs,and future potential

Populations of wild pigs (Sus scrofa) are burgeoning around the globe, and they are currently the target of extensive research and management efforts. Wild pigs are a highly successful invasive species that cause extensive damage to agriculture and native plant and animal communities. Lethal control is the most common management strategy used to reduce wild pig populations and their damage, and many lethal strategies rely on luring wild pigs to a specific location. Most commonly, a food commodity such as corn or maize (Zea mays) is used for attracting wild pigs to a site, but baiting with food is sometimes prohibited under wildlife laws, and visitation can be variable due to availability of alternative foods, level of harassment by humans, and acceptance of novel food source, devices, and activity. Wild pigs are highly adaptable with refined senses that enable them to interact with their environment and conspecifics in a complex manner. Wild and domestic pigs share keen senses, though differences exist due to suppressed stimuli, evolutionary gains and losses, or other factors related to needs for survival and fitness. Wild pigs routinely rely on acute olfaction to locate food, detect predators, and communicate with conspecifics. A pig’s sense of taste is also considered to be refined and more acute than that of humans. An abundance of evaluations regarding various attractants for wild pigs has been conducted over the last several decades; yet, a scarcity of conclusive results on which attractants to use when and where still exists. As such, we undertook a comprehensive review of available information on potential attractants that could be used to aid management strategies of wild pigs such as hunting/shooting, trapping, pharmaceutical delivery, or density estimation. To complete this review, we assimilated and synthesized the most relevant literature, provide recommendations, and identify attractant evaluation needs for the enhancement of the global management of wild pigs.     

Illegal meat hunting in serengeti: dynamics in consumption and preferences

Although wild meat is an important source of protein across Africa, patterns and reasons for its demand are poorly defined. A study was conducted on consumption by inhabitants of ten villages in five districts to the west of Serengeti National Park, Tanzania. The first sample of 600 villagers was systematically selected from village registers and surveyed using a questionnaire. The second sample consisted of 341 arrested illegal meat hunters. Nine species dominated by eland ( Taurotragus oryx ) and wildebeest ( Connachaetes taurinus ) in terms of meat taste and hunting vulnerability respectively were found to be most preferred or consumed. There were remarkable variations in consumption and preferences for each species amongst ethnic groups and localities. The economics of protein consumption indicates that wild meat is consistently cheaper and hence consumed more frequently than other meats. Respondents' topmost tasty meat – eland and topi ( Damaliscus lunatus ) – were rare; consequently, common species e.g. buffalo ( Syncerus caffer ) and wildebeest were the substitutes mostly consumed to supplement beef and fish. Presence of carnivore species on the menu clearly demonstrates survival techniques when availability changes. Wildlife managers should, therefore, bestow attention to the conservation of all species for a balanced ecosystem and species survival.     

Modern Hunting Practices and Wild Meat Trade in the Oil Palm Plantation-Dominated Landscapes of Sumatra,Indonesia

The ongoing expansion of plantation agriculture has changed the ecological, demographic, and social conditions of Southeast Asia’s forested areas, yet little is known about hunting practices in these novel landscapes. Using information from 73 in-depth interviews with hunters, agricultural workers and wild meat dealers in the Jambi province of Sumatra, Indonesia, we describe contemporary hunting practices, including how hunting methods, wildlife harvest and consumption rates vary between different indigenous and immigrant ethnic groups. Hunting is now primarily a commercial endeavor for harvesting wild boar (Sus scrofa) meat; over 7500 wild boars were sold in Jambi City alone in 2011. The Muslim majority avoids wild boar for religious reasons, but there is substantial local and export demand driven by Chinese and Christian Batak. We conclude that hunting within oil palm plantations may reduce crop damage from wild boar and also yield large amounts of wild meat with relatively little by-catch of threatened animals.     

Wildlife in the life of local people of the semi-arid Argentine Chaco

The semi-arid Argentine Chaco is inhabited by mestizo people, who live on an economy of subsistence based on the use of natural resources and livestock ranching. I investigated the dietary and economic importance of wildlife for local people. Through interviews and participant observation, I found that wildlife is used primarily as food, providing about a third of the total meat consumed by local peasants. Local people use at least 26 species of wildlife although they concentrate on few species. Small species, Chacoan cavies and armadillos, are consumed most, representing 48% of the total wild meat consumed. Consumption of wild meat follows seasonal patterns determined by hunting methods, preferences for meat quality and species activity patterns. The consumptive value of wild meat is high in comparison with wages, but lower in comparison with forest exploitation. Illegal commercialization of wildlife is practiced mainly by villagers and by outsiders and it affects endangered species. Patterns of use of wildlife by local people differ from other Latin American groups in terms of the range of species hunted and the role that hunting plays in local people’ livelihoods. The first steps towards conservation of this increasingly threatened region should involve decreasing hunting by local people of the more vulnerable species and controlling all illegal commercial hunting.     

A simple visual estimation of food consumption in carnivores

Belly-size ratings or belly scores are frequently used in carnivore research as a method of rating whether and how much an animal has eaten. This method provides only a rough ordinal measure of fullness and does not quantify the amount of food an animal has consumed. Here we present a method for estimating the amount of meat consumed by individual African wild dogs Lycaon pictus. We fed 0.5 kg pieces of meat to wild dogs being temporarily held in enclosures and measured the corresponding change in belly size using lateral side photographs taken perpendicular to the animal. The ratio of belly depth to body length was positively related to the mass of meat consumed and provided a useful estimate of the consumption. Similar relationships could be calculated to determine amounts consumed by other carnivores, thus providing a useful tool in the study of feeding behaviour.     

Oil industry, wild meat trade and roads: indirect effects of oil extraction activities in a protected area in north-eastern Ecuador

Starting in 1994, a wholesale wild meat market developed in north-eastern Ecuador, involving Waorani and Kichwa people in the area of influence of a road built to facilitate oil extraction within Yasuní National Park. Between 2005 and 2007, we recorded the trade of 11 717 kg of wild meat in this market, with pacas Cuniculus paca , white-lipped peccaries Tayassu pecari , collared peccaries Pecari tajacu and woolly monkeys Lagothrix poeppiggi accounting for 80% of the total biomass. Almost half of the wild meat brought to the market was transported by dealers for resale at restaurants in Tena, a medium-sized town 234 km west of the market. Prices of wild meat were 1.3–2 times higher than the price of meat of domestic animals, suggesting that it is a different commodity and not a supplementary protein source in the urban areas where it is consumed. The actual price of transportation between the local communities and the market was a significant predictor of the amount of meat sold in Pompeya. Based on this relationship the Waorani hunters sold exceptionally larger amounts of wild meat than would be expected if they would not have the transportation subsidies provided by the oil companies. Although the scale of this wild meat wholesale market is still relatively small, its dynamic reflects the complex interactions that emerge as the overriding influence of oil companies or other private industries modify the culture and subsistence patterns of marginalized indigenous groups, increasing their potential impacts on wildlife and natural ecosystems.     

Rural Bushmeat Consumption Within Multiple-use Protected Areas: Qualitative Evidence from Southwest Madagascar

Ensuring the sustainability of bushmeat consumption is critical for both biodiversity conservation and poverty alleviation in tropical developing countries, yet we know little about the role of hunting and bushmeat consumption in the daily lives of rural communities. We provide the first detailed, qualitative examination of bushmeat hunting activities conducted by a rural community within one of Madagascar’s new, multiple-use protected areas, in order to inform appropriate management strategies. Results suggest that most species are eaten, but that few are favoured above domestic meat. Hunting is generally a secondary pursuit, carried out opportunistically during the course of other activities, although its importance does increase in times of food stress. Management focused on increasing domestic meat availability and directing hunting effort away from sensitive species may improve the sustainability of hunting, but development interventions to reduce forest dependence may be required to promote conservation and poverty alleviation simultaneously.     

The ecological basis of hunter-gatherer subsistence in African Rain Forests: The Mbuti of Eastern Zaire

The Mbuti pygmies, hunter-gatherers of the Ituri Forest of Zaire, trade forest products and labor for agricultural foods. It has been assumed that the Mbuti lived independently in the equatorial forest prior to its penetration by shifting cultivators. We assessed forest food resources (plant and animal) to determine their adequacy to support a hunting and gathering economy. For five months of the year, essentially none of the calorically important forest fruits and seeds are available. Honey is not abundant during this season of scarcity. Wild game meat is available year round, but the main animals caught have low fat content. This makes them a poor substitute for starch-dense agricultural foods, now staples in Mbuti diet. In general, in the closed evergreen forest zone, edible wild plant species are more abundant in agriculturally derived secondary forest than in primary forest. Similarly, they are more common at the savanna ecotone and in gallery forests. We suggest that it is unlikely that hunter-gatherers would have lived independently in the forest interior with its precarious resource base, when many of the food species they exploit are more abundant toward the savanna border.     

Incentives for Hunting: The Role of Bushmeat in the Household Economy in Rural Equatorial Guinea

Bushmeat is an important component of the informal economy throughout West and Central Africa. In order to formulate effective policy to ensure the sustainability of bushmeat hunting for both development and conservation reasons, there is a need to understand its position within the wider rural economy. We conducted interviews with households and hunters over a 15-month period in a village in continental Equatorial Guinea which supplies substantial quantities of bushmeat to the urban market, to evaluate (1) whether hunting is predominately for income or consumption and through choice or necessity, and (2) the factors influencing household production of and consumption and expenditure on bushmeat. Hunting for trade to urban markets is a major component of household incomes, carried out by around 60% of poor-to-middle income households, while richer households have other income-generating activities. The greater a hunter’s bushmeat offtake, the higher the proportion sold. Bushmeat forms a minor component of household expenditure and is less widely consumed than alternative protein sources. It is a necessity good, with consumption and expenditure on bushmeat related less than proportionately to income. While they prefer the security of a regular wage, hunting is an important source of fall-back income for men in the absence of preferable alternative livelihood opportunities.     

First evidence of prey capture and meat eating by wild Yunnan snub-nosed monkeys Rhinopithecus bieti in Yunnan,China

Most extant nonhuman primates occasionally prey on fast-moving, warm-blooded animals; however, Indriidae, Lepilemuridae, and Colobinae either scavenged for meat or did not eat meat at all. Here we report six cases of animal consumption by the snub-nosed monkey Rhinopithecus bieti in a wild, habituated group between 2004 and 2009 in Yunnun, China. At present,only males in an all-male unit within the study group were involved in active hunting. Such a male-biased activity may be related to the group structure and spatial spread of R. bieti. Two females were observed eating freshly killed birds. The findings confirmed that R. bieti engaged in scavenging and, when hunting, employed a cranio-cervical bite to kill their prey. Meat eating is likely a nutrient maximization feeding strategy in R. bieti, especially in males. A begging behavior occurred after successful prey capture. Although begging was observed, no sharing of the meat was seen. The present findings illuminate the dietary diversity of R. bieti and their ability to expand their dietary spectrum.     

Development and use of wild game consumption rates in human health risk assessments

Clearer guidance is recommended for evaluating site-specific chemical risks due to the consumption of wild game in human health risk assessment (HHRA), particularly in estimating consumption rate values for site-specific exposure modeling. This study reviewed site-specific HHRAs, survey data, regulatory documents, and scientific literature to evaluate the state of the practice for evaluating site-specific chemical risks via wild game consumption. Consumption rates of distinct wildlife species groups varied over three orders of magnitude (increasing from lowest to highest: waterfowl, terrestrial birds, small mammals, and cervids), and rates for all groups except cervids were lower than wild fish consumption rates. Wild game consumption rate values should be explicitly derived for site-specific HHRAs using one or more of the following approaches (in general order of lowest to highest uncertainty): (1) Empirical site-specific surveys; (2) Empirical surveys of comparable communities; (3) Modeling of local game harvest data; (4) Use of a nationally applicable default value; (5) Modeling of legally harvestable game limits; and (6) Modeling based on estimates of total meat consumption. Data are readily available such that approximate nationally applicable default values could be developed. More precise guidance and data for different wildlife species groups, regions, and consumers would improve HHRAs including this exposure pathway.     

Effects of the hunting method on meat quality from fallow deer and wild boar and preliminary studies for predicting lipid oxidation using visible reflectance spectra

This study examines the influence of hunting methods on the colour and lipid oxidation state of meat from wild boar (Sus scrofa) and fallow deer (Dama dama). In addition, the feasibility of using visible reflectance spectra (360 to 740 nm) to predict the lipid oxidation of meat was evaluated. A total of 25 wild boars and 14 fallow deer were hunted with two different methods, dog-driven hunting (DH) and harvest culling (HC), that imply different animal stresses before shooting. Lipid oxidation increased in the meat from both species, which had been frozen for 3 months. The increase was higher in the DH group than the HC group (P?<?0.05). Our results confirm the importance of hunting stress on meat quality and lipid stability. The multivariate regression analysis showed a high correlation (R ²?=?0.968) between the predicted and measured thiobarbituric acid-reactive substances (TBARS) values, suggesting that visible spectroscopy should prove useful for predicting meat oxidation.     

DNA barcoding of traded shark fins,meat and mobulid gill plates in Singapore uncovers numerous threatened species

The shark and ray (Elasmobranchii) trade is a commercially valuable industry that has negative consequences for wild populations. An estimated 100 million sharks are caught each year to supply the demand for cultural cuisines, traditions and practices, including shark fin soup and Traditional Chinese Medicine. Despite the establishment of frameworks and regulations by international trade and conservation bodies as well as national legislations, elasmobranch populations continue to decline. While their conservation becomes an ever more pressing concern, a major obstacle that hampers regulation is the mislabelling and/or misidentification of dried products or carcasses that have had fins removed. Here we use DNA barcoding to identify the species of origin for a variety of shark and ray products readily available to consumers in Singapore, a major importer of these goods. We amplified a fragment of the cytochrome c oxidase subunit I gene from shark fin, cartilage and meat, as well as ray gill plates and meat for DNA sequencing. Our analysis of 207 DNA barcodes yielded 28 positively identified elasmobranch species, eight of which are listed under Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora, and 12 are listed as Endangered or Vulnerable by the International Union for the Conservation of Nature. This information will be useful to regulatory bodies in controlling trade and establishing new or revisiting previous conservation status listings.     

Dietary patterns with fresh fruits and vegetables consumption and quality of sleep among older adults in mainland China

With modern society’s increased pressures, problems arise regarding duration and quality of sleep. Many Chinese seniors report poor quality of sleep. With rapid urbanization, Chinese dietary patterns have shifted dramatically, with vegetables consumption declining rapidly. This research focuses on the associations between fruits and vegetables consumption with basic dietary behaviors and sleeping patterns. Using the 2014 wave of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), multinomial logistic regression models predicted older adults’ (age > = 65) quality and duration of sleep. Predictors included fruits and vegetables consumption, types of cooking oil, staple foods, and meat. The mean age of the study sample was around 85 years. Approximately 56% of respondents consumed fresh vegetables daily. A majority of seniors consumed rice as their staple food. Only 14% of seniors consumed fresh fruits daily. Most seniors consumed meat weekly or more frequently. We found that seniors who consumed fruits and vegetables occasionally had lower odds of reporting good quality of sleep [Fruits: AOR (Adjusted odds ratio) = 0.77; Vegetables: AOR = 0.58] compared with daily consumers. Respondents who reported consuming wheat and half rice-half wheat had higher odds of reporting good quality of sleep (Wheat: AOR = 1.52; Half rice-half wheat: AOR = 1.28), compared with seniors who reported rice as their staple food. Chinese public health practitioners and nutritionists should design dietary plans with more frequent consumption of fruits, vegetables, and wheat to help older adults’ overall health including their sleeping patterns.

     

Hunting income patterns among the Hadza: big game, common goods, foraging goals and the evolution of the human diet.

The assumption that large mammal hunting and scavenging are economically advantageous to hominid foragers is examined in the light of data collected among the Hadza of northern Tanzania. Hadza hunters disregard small prey in favour of larger forms (mean adult mass greater than or equal to 40 kg). Here we report experimental data showing that hunters would reduce their mean rates if they included small animals in the array they target. Still, daily variance in large animal hunting returns is high, and the risk of failure correspondingly great, significantly greater than that associated with small game hunting and trapping. Sharing large kills reduces the risk of meatless days for big game hunters, and obviates the problem of storing large amounts of meat. It may be unavoidable if large carcasses cannot be defended economically against the demands of other consumers. If so, then large prey are common goods. A hunter may gain no consumption advantage from his own big game acquisition efforts. We use Hadza data to model this 'collective action' problem, and find that an exclusive focus on large game with extensive sharing is not the optimal strategy for hunters concerned with maximizing their own chances of eating meat. Other explanations for the emergence and persistence of this practice must be considered.     

Coprophagy by wild ring-tailed lemurs (Lemur catta) in human-disturbed locations adjacent to the Beza Mahafaly Special Reserve, Madagascar

Coprophagy occurs in a number of animal species, including nonhuman primates. During the 2003-2004 dry seasons at the Beza Mahafaly Special Reserve, Madagascar, we observed wild ring-tailed lemurs (Lemur catta) consuming dried fecal matter from three different species. Ring-tailed lemurs consumed human feces on 12 occasions, cattle feces twice, and feral dog feces once. Coprophagy in this population may be a behavioral adaptation that provides animals access to energy and nutrients and may be an important nutritional source for older, and/or dentally impaired individuals during the dry season.
