The present study evaluated the efficacy of recently approved Salmonella lytic bacteriophage preparation (SalmoFresh™) in reducing on chicken breast fillets, as a surface and dip application. effectiveness phage combination with modified atmosphere packaging (MAP) ability fillets at room temperature was also evaluated. Chicken inoculated cocktail Typhimurium, S. Heidelberg, Enteritidis were treated (109 PFU/mL) either or treatment. dip-treated samples stored 4°C aerobically surface-treated...

Campylobacter is one of the main bacterial pathogens that cause campylobacteriosis in United States. Poultry considered a major reservoir for transmission to humans. This study aimed determine prevalence and molecular characteristics no-antibiotics-ever (NAE) broilers. A total 414 samples were collected, among which 160 retail chicken purchased from grocery stores 254 collected broiler farms located Mississippi State. The overall was 25.4%, significantly higher observed than farm (36.3%...

Avian pathogenic Escherichia coli causes one of the most detrimental bacterial diseases to United States poultry industry, colibacillosis. Colibacillosis leads decreased performance, early mortality, and subsequent production loss.

United States is the largest producer and second exporter of broiler meat in world. In U.S, production largely converting to antibiotic-free programs which has caused an increase morbidity mortality within farms. Escherichia coli Clostridium perfringens are two important pathogenic bacteria readily found environment result annual billion-dollar losses from colibacillosis, gangrenous dermatitis, necrotic enteritis. Broiler industry search non-antibiotic alternatives including novel vaccines,...

This study characterized biofilm formation of various Salmonella strains on common processing plant surface materials (stainless steel, concrete, rubber, polyethylene) under static and fluidic shear stress conditions. Surface-coupons were immersed in well-plates containing 1 mL (6 log CFU/mL) incubated aerobically for 48 h at 37 °C or Biofilm density was determined using crystal violet assay, cells enumerated by plating tryptic soy agar plates. Biofilms visualized scanning electron...

In poultry processing, Salmonella and Campylobacter contaminations are major food safety concerns. Peracetic acid (PAA) is an antimicrobial commonly used in commercial processing to reduce pathogen prevalence so as meet the USDA-FSIS performance standards. The objective of this study was determine on broiler meat various steps plants that use PAA. Post-pick, pre-chill, post-chill, drumstick chicken samples were collected from three mechanically deboned (MDM) two plants. Each plant sampled...

Highlights Broiler breast meat with white striping (WS) was imaged under sinusoidally modulated structured illumination. Amplitude component (AC) images resolved better WS characteristics than direct (DC) images. Models built on deep features classified samples into 2 and 3 classes according to severity. The AC consistently outperformed the DC achieved best accuracy of 96.6% in 2-class modeling. Abstract. Visual inspection is prevailing practice industry for assessing broiler meat. However,...

In poultry processing, spoilage microbes are persistent microorganisms, which affect the quality of broiler meat. Peracetic acid (PAA) is most common antimicrobial used by commercial processing plants, can reduce prevalence these microbes. The goal this study was to determine concentrations aerobic bacteria, coliforms, lactic and Pseudomonas on meat in plants that use peracetic various as primary antimicrobial. Samples were collected from three at five steps: post-pick (defeathering),...

The formation of Campylobacter jeuni biofilms on processing surfaces is a significant concern in poultry processing, contributing to food safety risks. This study focused assessing the biofilm forming capabilities 12 field isolates C. jejuni different aerotolerance categories stainless steel surfaces, prevalent material environments. Working cultures each isolate were prepared approximately 6 log CFU/mL and incubated coupons under microaerobic or aerobic conditions at room temperature 42°C...

Campylobacter jejuni (C. jejuni) is the most common food-borne pathogen that causes human gastroenteritis in United States. Consumption of contaminated poultry products considered as major source infection. An effective vaccine would be a promising alternative to antibiotic supplements curb C. colonization gastrointestinal (GI) tract. However, genetic diversity among isolates makes production more challenging. Despite many attempts, an not yet available. This study aimed identify suitable...

This study was conducted to investigate how dietary lysine level affects the intramuscular fat (IMF) content and fatty acid (FA) composition in late-stage finishing pigs. Nine crossbred barrows [94.4 ± 6.7 kg body weight (BW)] were randomly allotted three treatment groups (n = 3). Three corn- soybean-meal-based diets formulated meet National Research Council (2012) requirements for various nutrients except lysine, whose concentrations 0.43%, 0.71%, 0.98% (as-fed basis) Diets 1...

Clostridium perfringens (C. perfringens) is the etiological agent of necrotic enteritis and gangrenous dermatitis; 2 diseases that cause significant economic welfare concerns to broiler industry. Previously, Clostridium-related were managed with use antimicrobial growth promoters fed broilers improved gut health performance. The recent shift no antibiotics ever (NAE) production has increased incidence diseases. objective this study was identify C. prevalence toxinotypes in NAE farms. Samples...

The objective of this study was to compare consumer acceptability and demand between pre- post-rigor cooked beef sausage. Consumers (N = 100) evaluated the appearance, aroma, flavor, texture, overall on a 9-point hedonic scale formulated an independent bid for each product. preferred aroma flavor pre-rigor sausage those (P 0.008 0.029, respectively). This resulted in greater than that 0.011). Cluster analysis revealed 45 consumers clusters 3 4 led such acceptability. Average predicted...
