Application of 1,3-Dibromo-5, 5-Dimethylhydantoin as a Post-Chill Immersion and Spray Application to Reduce Campylobacter Jejuni Populations on Poultry
(2012-07-24)
Chemical antimicrobials are widely used throughout poultry processing to reduce and/ or eliminate poultryborne pathogens that could potentially cause illness in humans. Recent regulatory guidelines mandate that certain ...
Applications of Major and Minor Steviol Glycosides of Stevia rebaudiana in Complex Food Systems
(2023-07-27)
Stevia is an all-natural plant-based high-intensity sweetener comprised of major and
minor glycosides. Major glycoside, rebaudioside (Reb) A, is the most widely used glycoside in
the food industry but possesses a strong ...
Applying N-halamine Antimicrobial in Poultry Production and Food Processing for Improving Food Safety
(2017-07-22)
Food safety and food losses are drawing public attention, especially regarding meat and meat products. Using antimicrobial absorbent pads in packed meat trays and antimicrobial air filters in chicken production may provide ...
Ascaridia galli: Diagnosis, alternative treatments and influence on cytokine expression, microbiota, egg quality and digestibility
(2022-12-05)
Because of the trend of cage-free egg production, infections with the nematode Ascaridia galli are receiving increased attention. The aim of the first study was to evaluate and quantify the parasitological challenge in ...
Assessing the Scientific Basis of the Food Safety Modernization Act Produce Safety Rule and Microbial Quality of Water Used to Grow Produce in Alabama
(2019-03-05)
Small farms are a growing part of the fresh produce market. In Alabama, 93 percent of farms are defined as small and 2 percent of agricultural sales were from fresh produce in 2016. Only 1.3 percent of produce farms in ...
Assessment of early-stage thermal variation on embryonic mortality, hatchability, growth performance, and carcass characteristics of broiler chickens
(2022-12-05)
Timing and duration of thermal variation (TV) alters egg moisture loss, hatchability, chick BW, and performance. The objective was to evaluate the effect of TV during early-stage incubation on embryonic mortality, hatchability, ...
Assessment of Microbial Risk Factors Associated with Irrigation Water use on Small Alabama Farms
(2021-07-12)
Fresh produce is often associated with foodborne outbreaks as these products easily become contaminated with foodborne pathogens from the environment and poor handling practices. Approximately 46% of foodborne illnesses ...
Assessment of the Effects of Acid-Adaptation on the Thermal Tolerance of Listeria monocytogenes and Salmonella Heidelberg
