Abstract Liquid smoke, an alternative to traditional wood burning smoking, enhances product value by imparting desirable characteristics such as aroma, flavor, and color. Furthermore, it contains components with inherent antimicrobial and antioxidant properties. This study compares the effects of liquid smoke and conventional smoking methods in bacon processing.

Beef burgers are perishable meat products, and to extend their shelf life, EU Regulation 1129/11 permits the use of certain additives. However, given the concerns of health-conscious consumers and the potential toxicity of synthetic substances, this study aimed to explore the use of fennel waste extracts as natural preservatives.

Bitter apricot belongs to the genus Prunus and family Rosaceae and possesses bioactive compounds including oil with medicinal potential. A study was designed to investigate the food preservation and shelf‐life extension potency of bitter apricot seed kernel oil (BASKO). It was used as a coating material independently or pure oil coating (OC) and integrated with a film‐forming solution (FFS) for the extension of shelf‐life.

Radio frequency (RF) is a dielectric heating technology that allows rapid and volumetric heating of milk powder, outperforming the heating uniformity of conventional powder heating methods. Typically, RF milk powder processing consists of a fast RF heating phase, followed by an oven heating phase in temperatures around 90 °C. This methodology can result in milk powder quality deterioration due to non-uniform temperature distributions and local overheating.

Abstract In this study, microcapsules of Lactiplantibacillus plantarum 299V were prepared using an emulsification/internal gelation technique. Loads of the probiotics were condensed to 9.86 ± 0.13 log CFU/g after 24 h fermentation of the microcapsules. Physical characterization revealed that L.

Antibiotic-resistant Salmonella is one of the main public health concerns in the world. Isolation of Salmonella in abattoirs has been considered the core source of infection in the community from meat. Still, the...

Abstract Tilapia stands out as one of the most extensively farmed and consumed fish species globally, valued for its ease of preparation and relative affordability. Although tilapia is a valuable protein source, it can also function as a vector for foodborne pathogens.

Managing bacterial infections is of great importance in cattle production, particularly those caused by Salmonella enterica serovars Typhimurium or Dublin, which can impact both animal health and human food safety. Direct-fed microbial (DFM) can support gastrointestinal health and alleviate potential bacterial infections.

Our objective was to longitudinally assess the presence and quantity of Salmonella enterica throughout the gastrointestinal tract of finishing beef steers with and without liver abscesses (LA). Crossbred steers [n = 225; initial body weight (BW) = 353 ± 39 kg] were used in an observational case-control design with individual steer designated as the experimental unit.

We evaluated the association of diet type, ruminal acidosis bout frequency, and intraruminal bacterial inoculum concentration on liver abscess (LA) development in steers. Beef × dairy steers [n = 40, initial body weight (BW) = 107 ± 11 kg] were assigned randomly to 1 of 5 treatments that included either a high-dose (HD; 1 × 109 and 1 × 109 CFU/mL) or a low-dose (LD; 1 × 106 and 1 × 106 CFU/mL) of Fusobacterium necrophorum subsp.

Our objective was to evaluate hematological measurements that could be indicative of liver abscesses (LA) in weaned beef × dairy cross steers. Beef × dairy cross steers [n = 40; initial body weight (BW) = 120 ± 12 kg] were sourced from a local dairy calf ranch and transported 166 km to the USDA-ARS Livestock Issues Research Unit Liberty Farm near Lubbock, TX (d -16).

Almost 100 yr ago, food safety concerns in Canadian livestock were very different than they are today. In the 1920s Brucella spp. which causes ‘undulant fever’ in humans was a major zoonotic pathogen. The main route of transmission of Brucella spp. was through consumption of unpasteurized milk, often from the family milk cow.

Body weight (BW) is an important component of pig productivity. Understanding the metabolic factors affecting growth rate is key to guiding nutritional strategies and bringing economic benefits to pig farms. Machine learning (ML) algorithms have been used to capture patterns in large datasets and predict animal production traits based on integrated information of performance data and blood records.

Butyrate is a microbial-produced metabolite associated with increased barrier integrity, enhanced mucosal immunity, and modulation of immune cell function. Butyrate driven immunomodulation occurs through a variety of mechanisms, including signaling via cell surface G protein-coupled receptors. Myeloid lineage cells serve as one of the first lines of defense during infection.

Immune system activation alters the demand for amino acid (AA) supply, and amino acid-based nutritional strategies may mitigate performance reduction in pigs subjected to a sanitary challenge (SC).

Liver abscesses (LA) continue to be an economic challenge for the beef industry. Chronic ruminal acidosis and ruminitis contribute to LA development. Fusobacterium necrophorum subsp. necrophorum, a ruminal bacterium, is the primary causative agent. Damaged ruminal, and possibly other gut regions, become susceptible to invasion and colonization by subsp. necrophorum, which reaches the liver via portal blood to cause abscesses.
