Abstract

The objective of this investigation was to evaluate Salmonella and Yersinia enterocolitica prevalence in wild boars hunted in Sardinia and further characterize the isolates and analyse antimicrobial resistance (AMR) patterns. In order to assess slaughtering hygiene, an evaluation of carcasses microbial contamination was also carried out. Between 2020 and 2022, samples were collected from 66 wild boars hunted during two hunting seasons from the area of two provinces in northern and central Sardinia (Italy). Samples collected included colon content samples, mesenteric lymph nodes samples and carcass surface samples. Salmonella and Y. enterocolitica detection was conducted on each sample; also, on carcass surface samples, total aerobic mesophilic count and Enterobacteriaceae count were evaluated. On Salmonella and Y. enterocolitica isolates, antimicrobial susceptibility was tested and whole genome sequencing was applied. Salmonella was identified in the colon content samples of 3/66 (4.5%) wild boars; isolates were S. enterica subs. salamae, S. ser. elomrane and S. enterica subs. enterica. Y. enterocolitica was detected from 20/66 (30.3%) wild boars: in 18/66 (27.3%) colon contents, in 3/66 (4.5%) mesenteric lymph nodes and in 3/49 (6.1%) carcass surface samples. In all, 24 Y. enterocolitica isolates were analysed and 20 different sequence types were detected, with the most common being ST860. Regarding AMR, no resistance was detected in Salmonella isolates, while expected resistance towards β-lactams (blaA gene) and streptogramin (vatF gene) was observed in Y. enterocolitica isolates (91.7% and 4.2%, respectively). The low presence of AMR is probably due to the low anthropic impact in the wild areas. Regarding the surface contamination of carcasses, values (mean ± standard deviation log10 CFU/cm2) were 2.46 ± 0.97 for ACC and 1.07 ± 1.18 for Enterobacteriaceae. The results of our study confirm that wild boars can serve as reservoirs and spreaders of Salmonella and Y. enterocolitica; the finding of Y. enterocolitica presence on carcass surface highlights how meat may become superficially contaminated, especially considering that contamination is linked to the conditions related to the hunting, handling and processing of game animals.

Abstract

Vertaisarvioitu. Luonnonvaraisten villisikojen määrä on viime vuosina lisääntynyt rajusti useassa Euroopan maassa, myös Suomessa. Villisiat ovat osoittautuneet useiden zoonoottisten taudinaiheuttajien eläinvarastoksi, reservoaariksi. Villisikakannan suurentuessa lisääntyy myös todennäköisyys, että niissä esiintyvät taudinaiheuttajat leviävät ihmisiin, eläimiin ja ympäristöön. Leviäminen voi tapahtua suoraan eritteiden kautta tai epäsuorasti saastuneen lihan välityksellä. Tärkeimpiin villisian lihan välityksellä leviäviin zoonooseihin lukeutuvat salmonelloosi, yersinioosi, toksoplasmoosi, trikinelloosi ja E-hepatiitti. Lisääntynyt metsästys ja luonnonvaraisen villisian lihan kulutus voivat altistaa kuluttajat villisianlihavälitteisille taudinaiheuttajille. Metsästäjien ja heidän perheenjäsentensä tartuntariski on suurin, sillä he käsittelevät ja kuluttavat suurimman osan kotimaisesta villisian lihasta. Tartuntariskiä voidaan vähentää hyvällä metsästys-, teurastus- ja käsittelyhygienialla sekä välttämällä raa'an tai riittämättömästi kypsennetyn villisian lihan syöntiä.

45. Hunted game birds – Carriers of foodborne pathogens

Abstract

Game birds may carry zoonotic bacteria in their intestines and transmit them to hunters through bird handling or through the handling and consumption of contaminated meat. In this study, the prevalence of foodborne bacteria was screened from game bird faeces and mallard breast meat using PCR. The sampling occurred in southern Finland from August to December during the hunting season. Isolates were characterized by multi-locus sequence typing. Mesophilic aerobic bacteria and Escherichia coli counts were used to assess the microbial contamination of mallard meat. In total, 100 woodpigeon (Columba palumbus), 101 pheasants (Phasianus colchicus), 110 mallards (Anas platyrhynchos), and 30 teals (Anas crecca) were screened during the hunting season. Additionally, 100 mallard breast meat samples were collected. Campylobacter and Listeria were commonly detected in the faeces and Listeria on mallard meat. L. monocytogenes of sequence types associated with human listeriosis were frequently found in game bird faeces and on mallard meat. Good hygiene during game bird handling, storing the game bird meat frozen, and proper heat treatment are important measures to minimize the health risk for hunters and consumers.
