African pythons (Pythonidae) and large vipers (Bitis spp.) act as definitive hosts for Armillifer armillatus and Armillifer grandis parasites (Crustacea: Pentastomida) in the Congo Basin. Since the proportion of snakes in bushmeat gradually increases, human pentastomiasis is an emerging zoonotic disease. To substantiate the significance of this threat, we surveyed snakes offered for human consumption at bushmeat markets in the Kole district, Democratic Republic of the Congo, for the presence of adult pentastomids...

This study focused on the use of antimicrobial edible coatings and films from micro-emulsions to reduce populations of foodborne pathogens in foods. Corn-Bio-fiber gum (C-BFG) was used as an emulsifier with chitosan. Allyl isothiocyanate (AIT) and lauric arginate ester (LAE) served as antimicrobials. Micro-emulsions were obtained from a solution consisting of 1% chitosan, 0.5% C-BFG, and 1-4% AIT or LAE which was subject to high pressure homogenization (HPH) processing at 138MPa for 3cycles. Coatings and films produced from the micro-emulsions had micro-pores with sizes ranging from 100 to 300nm and micro-channels that hold antimicrobials effectively and facilitate the release of antimicrobials from the center to the surface of the films or coatings, thus enhancing their antimicrobial efficacy...

The inactivation of Salmonella during curing of Italian traditional pork salami was investigated. A total of 150 batches of ground raw meat (GRM) used for salami manufacturing by four producers were tested for Salmonella by real-time PCR followed by ISO 6579 cultural confirmation and MPN enumeration. Salami produced with Salmonella positive GRMs were re-tested at the end of their curing period. Aw, pH and NaCl content were also measured. Detection of Salmonella was performed testing both 25 and 50g of the samples...

Lactococcus lactis subsp. lactis CRL 1584 isolated from a bullfrog hatchery produces a bacteriocin that inhibits both indigenous Citrobacter freundii (a Red-Leg Syndrome related pathogen) and Lactobacillus plantarum, and Listeria monocytogenes as well. Considering that probiotics requires high cell densities and/or bacteriocin concentrations, the effect of the temperature on L. lactis growth and bacteriocin production was evaluated to find the optimal conditions. Thus, the growth rate was maximal at 36 °C, whereas the highest biomass and bacteriocin activity was achieved between 20 and 30 °C and 20-25 °C, respectively...

Dissociating meat from its animal origins helps consumers deal with the cognitive dissonance resulting from liking meat but disliking causing pain to animals. Extending previous research, we tested whether dissociation would play less of a role for meat consumption in a country where average consumers are more frequently exposed to unprocessed meat (i.e., Ecuador) than where such exposure is rare (i.e., the US). Specifically, we randomly showed Ecuadorians and US Americans a pork roast with the head present or removed...

Today, in vitro (Latin: in glass) meat researchers strive to overhaul meat production technologies by producing meat outside animal bodies, primarily by culturing cells. In the process, meat should become healthier, more environmentally friendly and kinder to animals. In this article, I scrutinize (and problematize) this promissory discourse by examining the world that proponents envision alongside the world from which promises emerge. First, I trace the increasing number of publications striving to pinpoint the nature of in vitro meat to unveil the creation of an in vitro meat canon wherein perceived possibilities become taken for granted...

Salmonella spp. have been shown to migrate to the internal regions of meat cuts. Storage conditions and the presence of proteolytic microbiota can influence this process. Our study assessed the impact of storage time, temperature, and the presence of proteolytic psychrotrophic bacteria on migration. Samples of previously frozen chicken breast with skin and bone were then sterilized using gamma ray irradiation and a cobalt-60 source (11 KGy) and them were inoculated with cultures of S. Enteritidis, S. Enteritidis and psychrotrophs, S...

Over the last decades, much research has focused on lactic acid bacteria (LAB) bacteriocins because of their potential as biopreservatives and their action against the growth of spoilage microbes. Meat and fermented meat products are prone to microbial contamination, causing health risks, as well as economic losses in the meat industry. The use of bacteriocin-producing LAB starter or protective cultures is suitable for fermented meats. However, although bacteriocins can be produced during meat processing, their levels are usually much lower than those achieved during in vitro fermentations under optimal environmental conditions...

Crocodiles exist in unsanitary environments, feed on rotten meat, are often exposed to heavy metals such as arsenic, cadmium, cobalt, chromium, mercury, nickel, lead, selenium, tolerate high levels of radiation, and are amid the very few species to survive the catastrophic Cretaceous-Tertiary extinction event, nonetheless they can live for up to a 100 years. Moreover, as they live in unhygienic conditions, they regularly come across pathogens. Logically, we postulate that crocodiles have established mechanisms to defend themselves from noxious agents as well as protecting themselves from pathogens...

This paper focuses on the motives for vegetarian choices in contemporary Italian food culture, with specific reference to the role of the representations of death. The study adopts a qualitative research design aimed at an in-depth exploration of the reasons for avoiding meat, following an ethnographic method. Twenty-two participants (55% women, 45% men) aged 19-74, all vegetarians or vegans, mainly from Northern and Central Italy, were involved. Data from the Interpretative Phenomenological Analysis were examined according to the qualitative thematic analysis: the results show the role of death in the construction of disgust towards meat, running parallel with an emphasis on spirituality, ethical treatment of animals and the environment as reasons for avoiding meat, in particular, the concern-generating disgust and its relationship with the representation of death as a contaminating essence...

REVIEW
Monique Zagorec, Marie-Christine Champomier-Vergès
Among lactic acid bacteria of meat products, Lactobacillus sakei is certainly the most studied species due to its role in the fermentation of sausage and its prevalence during cold storage of raw meat products. Consequently, the physiology of this bacterium regarding functions involved in growth, survival, and metabolism during meat storage and processing are well known. This species exhibits a wide genomic diversity that can be observed when studying different strains and on which probably rely its multiple facets in meat products: starter, spoiler, or protective culture...
