Clostridium difficile is a cause of diarrhea and colitis in humans. The increase of incidence and severity of C. difficile infections in humans in past years is due, at least in part, to the emergence of more virulent strains (PCR ribotypes 027 and 078). Recent studies describe the occurrence of hypervirulent strains in ground meat products. Therefore, food animals and food need to be assessed for their possible role as vectors of C. difficile to humans. In this pilot study, fecal samples of 204 calves and 165 pigs, as well as 46 minced meat products were investigated to determine the occurrence of C. difficile in farm animals at slaughter and in ground meat products at the retail level in Switzerland. C. difficile was isolated from only one fecal sample of a calf. All samples from pigs and ground meat were negative. Further characterization revealed that the isolated strain harbored genes for toxins A and B as well as binary toxin, and belonged to the ribotype 078. Based on these results, low occurrence of C. difficile in farm animals at slaughter and retail ground meat in Switzerland is postulated. However, further studies are necessary to confirm these preliminary data and to assess future trends.

Background And Aim: Several approaches have been employed to mitigate methane emissions from livestock, with varied results. This study evaluated the effects of shade-dried ground garlic leaf (GL) powder and papaya leaf (PL) powder as crop waste on feed intake, growth performance, ruminal microbial counts, gut epithelial barrier functions, and meat quality in goats.
Materials And Methods: Forty male adult Beetal goats were randomly divided into five treatment groups: (1) Control (basal diet only); (2) basal diet supplemented with 6% bromodichloromethane (BCM); (3) basal diet supplemented with 30% GL powder; (4) basal diet supplemented with 26% PL powder; and (5) basal diet supplemented with 30% GL powder and 26% PL powder (GP).
Effect of Physiologically Relevant Dehydration on the Dielectric Properties of Ground Beef.

Readily available animal tissue, such as ground beef, is a convenient material to represent the dielectric properties of biological tissue when validating microwave imaging and sensing hardware and techniques. The reliable use of these materials depends on the accurate characterization of their properties. In this work, the effect of physiologically relevant levels of dehydration on ex vivo tissue samples is quantified while controlling for variation within and between samples.

non-typhoidal is a major contributor to diarrheal diseases, with over 2600 serovars identified across diverse environments. In Mexico, serovars Newport and Anatum have shown a marked increase, especially in foodborne disease, posing a public health problem. We conducted a cross-sectional study from 2021 to 2023 using active epidemiological surveillance to assess contamination in ground beef and pork at butcher shops nationwide.

Natural selection and artificial breeding are crucial methods for developing new animal groups. The Baiyu black goats and Chuanzhong black goats are indigenous goat breeds from distinct ecological regions in Sichuan Province, with dramatically different growth and reproductivity. This study aimed to systematically elucidate the differences in production performance and genetic traits between Baiyu black goats and Chuanzhong black goats.

The increasing demand for protein-rich, plant-based foods has driven the development of meat analogs that closely mimic the texture and mouthfeel of animal meat. While plant-based fibrils and electrospun silk fibroin fibers have been explored for texture enhancement and scaffolding in both meat analogs and cell-based meats, the use of wet-spun fibroin protein fibers as a food ingredient remains underexplored. This study investigates the potential of wet-spun recombinant fibroin fibers to enhance the textural properties of meat analogs.
