This study provides a framework of the factors predicting the intention of eating an insect-based product. As part of the study, a seminar was carried out to explore how the provision of information about ecological, health, and gastronomic aspects of entomophagy would modify consumer beliefs regarding insects as food. Before and after the informative seminar, two questionnaires about sociodemographic attributes and beliefs about the consumption of insects as food were given. Participants were then asked to carry out a sensory evaluation of two identical bread samples, but one was claimed to be supplemented with insect powder. Results showed that perceived behavioral control is the main predictor of the intention, followed by neophobia and personal insect food rejection. The disgust factor significantly decreased after the participants attended the informative seminar. Sensory scores highlighted that participants gave “insect-labelled” samples higher scores for flavor, texture, and overall liking, nevertheless, participants indicated that they were less likely to use the “insect-labelled” bread in the future. Our findings provide a better understanding of insect food rejection behavior and help to predict the willingness to try insect-based products based on some important individual traits and information.

Dogs can be infected by several nematodes of the Trichuridae family. Trichuridae eggs are all similar, barrel shaped with polar plugs, and misdiagnosis among different species can occur. The most common species is Trichuris vulpis, while the respiratory parasites Eucoleus boehmi (syn. Capillaria boehmi) and Eucoleus aerophilus (syn. Capillaria aerophila) are rarely observed in pets. E. boehmi is reported for the first time in this study in north-western Italy with other Trichuridae. Dog faecal samples (270) were examined by flotation. E. boehmi (2.2%), E. aerophilus (4.4%) and T. vulpis (12.2%) were found; identification was done with measurements and through observation of morphological characters already known. The specific identification of E. boehmi was confirmed using scanning electron microscopy: its egg shell shows a dense network with a fine mesh, surrounding small pits, on the contrary E. aerophilus eggs present a thick mesh with wide depressions, while T. vulpis eggs surface is smooth.

Borrelia burgdorferi sensu lato (s.l.) and Anaplasma phagocytophilum are well known zoonotic pathogens, whereas Ehrlichia canis is usually considered to be of veterinary concern, although on the basis of recent reports it also seems to be able to infect humans. The aim of the study was to determine the seroprevalence of B. burgdorferi s.l., A. phagocytophilum and E. canis in an Italian canine population, and to verify if there are differences between dogs living in urban areas and those from a rural environment. Blood sera of 1,965 dogs, 1,235 from cities and 730 from rural areas, were tested by indirect immunofluorescent assay (IFAT). The overall seroprevalence was highest for E. canis (7.07%), followed by A. phagocytophilum (4.68%), and B. burgdorferi s.l. (1.47%). Rural dogs showed the highest seroprevalence to B. burgdorferi s.l. and A. phagocytophilum. No significant differences were observed between rural and urban E. canis-positive dogs. A low percentage (1.32%) of dogs with dual seropositivity was detected, and no triple positive reactions were observed. No significant differences were detected in the seroprevalence of the three agents in relationship to the age and gender of the dogs. Seroprevalence in the five years considered were not statistically different, except for the lowest rate for E. canis observed in 2012. The results confirm the presence of B. burgdorferi s.l., A. phagocytophilum and E. canis in Italian dogs in both urban and rural areas. Monitoring pet dogs, which share the same environment with their owners, is useful for identifying the presence of tick-borne disease agents of both veterinary and public health significance.

The aim of this work is to study the influence of gender, age and hunting period on the fatty acid composition of the longissimus dorsi muscle excised from 42 wild boars hunted on a farm located in Tuscany. A sub-sample of 22 muscles was used for the study of the microbiological profile of wild boar meat. The results show that gender had an effect only on C16:1 n7, which was higher in females (p ≤ .05). Slaughtering age influenced more parameters, thus resulting in a higher content of C6:0, C18:2, C20:1 and n6/n3 ratio in meat from adults (p ≤ .05) and in a higher percentage of C16:0 (p ≤ .05) in meat from young animals. The hunting month greatly influenced the meat quality because, in addition to the single fatty acids, it significantly modified the MUFA, PUFA, PUFA/SFA and n6/n3 ratio, underlining the great difference between meat of wild boar shot in October – November vs December – January. Ether extract was higher in sub-adults than in young animals (p ≤ .01) but was not influenced by gender and hunting month. Regarding the microbiological analyses, Salmonella spp. was only detected in one sample, while Yersinia enterocolitica was not detected at all. Data on the presence of pathogenic bacteria confirmed health risk for the consumer comparable to that associated with meat obtained from farm animals, while data on microbial loads (total aerobic mesophilic and psychrotrophic counts, Enterobacteriaceae, Escherichia coli) did not highlight any specific criticality.
