“…Despite these incidents are in general poorly investigated, there is evidence that abandoned pot-bellied pigs have the capacity to form sounders that remain in natural habitats in Southern Europe and interact with wild boar populations increasing the population of hybrids. This is becoming a common phenomenon in many countries were pot-bellied pigs are sold as pets and has been currently described in rural areas of Southern and Northern Spain (Delibes-Mateos & Delibes, 2013;Soler et al, 2021). Based on our results, this kind of interaction is worth reporting in this study, to raise awareness about this phenomenon and encourage French and EU authorities to monitor this kind of incidents and their impact among wild boar populations.…”

“…Considering that sexual interactions reported by hunters occurred around the town where this farm was located, the possibility of cross breeding between wild boars and pot-bellied pigs is a plausible scenario. The abandonment of exotic pets can have serious consequences for the environment (Lockwood et al, 2019) and this is also applicable in the case of pigs kept as pets (Soler et al, 2021). In many EU countries, there are numerous shelters organisations dedicated to the rescue of abandoned pot-bellied pigs specimens.…”

“…This phenomenon is growing in developed countries purchasing pot-bellied pigs as pets but has been only reported in scientific literature very occasionally to date. (Delibes-Mateos & Delibes, 2013;Soler, Casas, Closa-Sebastià, Sanz, & Martorell, 2021).…”

Pig outdoor farming is gaining popularity and commercial success in the EU and its expansion, together with an increasingly abundance of wild boar populations facilitates interactions between domestic and wild suids. In the Southern French Department of Ardèche, several episodes of mass mortalities due to infection with an enteropathogenic strain of Escherichia coli, causing oedema disease (OD) were reported in wild boar populations between 2013 and 2016. In order to investigate a potential link between those events and the frequency of interactions between wild boar and domestic pigs, we analysed regional vegetation and hunting bag data and implemented a semi-structured questionnaire survey among a total of 30 outdoor pig farmers and 30 hunters distributed inside and outside the identified area of OD emergence. One third of interviewed farmers (11/30) had experienced intrusions of wild boars in domestic pig premises during the previous year. Similarly, 23% of interviewed hunters reported interactions between wild boar and feral free ranging pigs in recent years and 60% reported the observation of free ranging pigs with a phenotypic feature of Vietnamese pot-bellied pigs (55%). Our analysis identified that the OD emergence area gathered several factors that could facilitate interactions between wild and domestic suids including a predominance of forested vegetation, a higher estimated wild boar density, weaker levels of farm biosecurity and a higher level of reported intrusions or interactions with wild boar in pig farms. Despite our sample was limited, our study suggests that the occurrence and dissemination of wild domestic suid interactions in this region might be higher than expected and sufficient to facilitate the circulation of shared pathogens between wild and domestic suids. Similar studies in this and other rural regions in the EU are recommended, in order to identify risk areas and anticipate preparedness for the emergence and circulation of shared swine pathogens.

“…However, the purchase and ownership of pot‐bellied pigs are rarely regulated by national administrations, despite there is evidence that abandoned pot‐bellied pigs have the capacity to form feral sounders that remain in natural habitats in Southern Europe and interact with wild boar populations increasing the population of hybrids. This is becoming a common phenomenon in many countries where pot‐bellied pigs are sold as pets and has been currently described in rural areas of Southern and Northern Spain (Delibes–Mateos & Delibes, 2013 ; Soler, Casas, Closa‐Sebastià, Sanz, & Martorell, 2021 ). Based on our results, this kind of interaction is worth reporting in this study, to raise awareness about this phenomenon and encourage French and EU authorities to monitor similar incidents and their impact among WB populations.…”

Pig outdoor farming is gaining popularity and commercial success in the European Union, and its expansion, together with an increasing wild boar population, facilitates interactions between domestic and wild suids. In the Southern French Department of Ardèche, several episodes of mass mortalities due to infection with an enteropathogenic strain of Escherichia coli causing oedema disease (OD) were reported in wild boar populations between 2013 and 2016. In order to investigate a potential link between those events and the frequency of interactions between wild boar and domestic pig, we analyzed regional vegetation and hunting bag data and implemented a semi-structured questionnaire survey among a total of 30 outdoor pig farmers and 30 hunters distributed inside and outside the identified area of OD emergence. One third of interviewed farmers (11/30) had experienced intrusions of wild boars in domestic pig premises during the previous year. Similarly, 23% of interviewed hunters reported interactions between wild boar and feral free-ranging pigs in recent years, and 60% reported the observation of free-ranging pigs with a phenotypic feature of Vietnamese pot-bellied pigs (55%). Our analysis identified that in the OD emergence area, several factors could facilitate the transmission of pathogens between wild and domestic suids including a predominance of forested vegetation, a higher estimated wild boar density, weaker levels of farm biosecurity, a higher level of reported wild boar intrusions in pig farms and several reports of feral pot-bellied pig presence. Although our sample was limited, our study suggested a widespread occurrence of situations facilitating the transmission of pathogens between wild and domestic suids. Similar studies in other rural regions in the European Union are recommended, in order to promote preparedness for the emergence and circulation of shared swine pathogens.

“…ASF includes per-acute, acute, sub-acute and chronic manifestations that can result in skin erythema, pulmonary oedema, splenomegaly, haemorrhagic lymphadenitis, petechial haemorrhages in lungs, urinary bladder and kidneys. Other clinicals signs are delayed growth, emaciation, joint swelling and skin ulcers (Yoo et al, 2020).…”

Miniature pigs have gained popularity as companion animals in the recent years in Spain. Because the abandonment of miniature pigs and crossing breeds with wild boars can cause severe problems, investigation about the health status is needed. Two-hundred and eleven miniature pigs ( Sus scrofa) were included in the study to determine their health status according to the clinical findings during physical examination and the results of antibody serology tests against selected infectious diseases. Their origin, age sex, housing conditions and diet were recorded. The housing of the animals ranged from wild animals to animals living in animal sanctuaries. The diet varied from a natural diet in the wild to commercial and homemade food. Thirty animals out of two-hundred and eleven were hybrids between miniature pigs and wild boars according to morphological characteristics. Antibody serology techniques of Influenza A virus, Hepatitis E virus, brucellosis, tuberculosis, African swine fever, Classical Swine fever and Aujeszky´s disease was performed. The prevalence for Influenza A was 5.30%, for Hepatitis E was 5.35% and the rest tested negative. It is important to control and monitor these zoonotic infections to prevent Public Health problems. The results obtained from this investigation demonstrated that the health status of the animals in this study is optimal and the prevalence of diseases is similar or minor when compared to previous studies. This study confirms the hybridization of miniature pig and wild boar in Catalonia.
