Chronic inhalation exposure to agricultural dust promotes the development of chronic respiratory diseases among poultry workers. Poultry dust is composed of dander, chicken feed, litter bedding and microbes. However, the microbial composition and abundance has not been fully elucidated. Genomic DNA was extracted from settled dust and personal inhalable dust collected while performing litter sampling or mortality collection tasks. DNA libraries were sequenced using a paired-end sequencing-by-synthesis approach on an Illumina HiSeq 2500. Sequencing data showed that poultry dust is predominantly composed of bacteria (64–67%) with a small quantity of avian, human and feed DNA (< 2% of total reads). Staphylococcus sp. AL1, Salinicoccus carnicancri and Lactobacillus crispatus were the most abundant bacterial species in personal exposure samples of inhalable dust. Settled dust had a moderate relative abundance of these species as well as Staphylococcus lentus and Lactobacillus salivarius. There was a statistical difference between the microbial composition of aerosolized and settled dust. Unlike settled dust composition, aerosolized dust composition had little variance between samples. These data provide an extensive analysis of the microbial composition and relative abundance in personal inhalable poultry dust and settled poultry dust.

Microbiological Control And Mechanisms Of Action Of High Voltage Atmospheric Cold Plasma, Lu Han

Doctoral

Dielectric barrier discharge-atmospheric cold plasma (DBD-ACP) is a promising non-thermal technology effective against a wide range of microorganisms. These studies were performed using a custom built DBD-ACP system. The inactivation efficacy was found to be governed by a series of critical control parameters, including treatment time, mode of exposure (Direct/Indirect exposure), applied voltage, applied gas content but was also very dependent on the characteristics of treatment targets. In this study, these parameters were investigated using in-package design along with a post-treatment storage procedure to align with industrial processing times as well as mitigation of post-process contamination. A range of food …

Robotics In Meat Processing, Kompal Joshi, Tomas Norton, Jesus Maria Frias, Brijesh K. Tiwari

Books/Book Chapters/ Proceedings

Scientists are currently investigating micro-robotics in the medical field with a potential to provide better medical technology in the near future. When it comes to the food industry, the use of robots has been traditionally limited to picking and palletization. Today, however, robots are used in material handling and secondary or tertiary packing. Recent developments with faster computers and sophisticated sensors have made it possible to use robotics in the meat processing sectors, where their application has reduced processing costs, occupational injuries, improved efficiency and hygiene associated with meat products. Compared to other industries, the working environment in the meat …

Identification Of Species In Ground Meat Products Sold On The U.S. Commercial Market Using Dna-Based Methods, Dawn Kane, Rosalee S. Hellberg

Food Science Faculty Articles and Research

The objective of this study was to test a variety of ground meat products sold on the U.S. commercial market for the presence of potential mislabeling. Forty-eight ground meat samples were purchased from online and retail sources, including both supermarkets and specialty meat retailers. DNA was extracted from each sample in duplicate and tested using DNA barcoding of the cytochrome c oxidase I (COI) gene. The resulting sequences were identified at the species level using the Barcode of Life Database (BOLD). Any samples that failed DNA barcoding went through repeat extraction and sequencing, and due to the possibility of a …

Dna Barcoding Reveals Mislabeling Of Game Meat Species On The U.S. Commercial Market, Charles Quinto, Rebecca Tinoco, Rosalee S. Hellberg

Food Science Faculty Articles and Research

Game meats represent a valuable specialty market in the United States that has high economic incentives associated with mislabeling. However, there is limited information on this topic. The purpose of this study was to conduct a market survey of game meats sold within the United States and identify instances of mislabeling using DNA barcoding. Products were also examined for the presence of threatened or endangered species. Fifty-four samples of whole-cut game meats were collected from online distributors in the United States and sequenced across a 658 base-pair region of the cytochrome c oxidase subunit I (COI) gene. The resulting DNA …

Acoustic Emission Of Lactococcus Lactis Ssp. Lactis C2 Infected With Three Bacteriophages C2, Sk1 And Ml3, Luxi Meng

Theses and Dissertations--Animal and Food Sciences

The objective of this research was to monitor the Acoustic Emission (AE) produced by Lactococcus lactis ssp. lactis C2 infected with three bacteriophages (c2, sk1 and ml3 at 90 min) using an acoustic emission-monitoring device which was designed at University of Kentucky in Lexington KY. The acoustic emission data was collected and then analyzed. These Acoustic Emission (AE) data suggested that bacteriophage ml3, sk1 and c2 can easily be distinguished by the differences in Absolute Energy (ABE), Centroid Frequency (CF) and Peak Frequency (PF) signals. The AE data suggested that bacteriophage sk1 and c2 caused greater stress on the lactis …

Simultaneous Determination Of Bpa And Bps Using Uv/Vis Spectrophotometry And Hplc, Jean Eudes Benecyo

Honors Theses

Bisphenol A (BPA) has been one of the most used plasticizers with more than 4.8 million tons produced in 2012. BPA is also an endocrine disruptor that has been linked to adverse health effects such as cancer, obesity, behavioral and mood changes, lowered fertility, developmental changes and more in humans and other animals. The evidence of the toxicity of BPA, even at very low levels, has caused many countries to limit its use, especially in baby bottles and other baby-related hard plastic items. In these times, BPA has been replaced with other bisphenols, such as Bisphenol S (BPS). BPS is …

Physico-Chemical, Rheological And Baking Properties Of Proso Millet, Manjot Singh

Theses and Dissertations--Biosystems and Agricultural Engineering

Due to climate change, water scarcity, increasing population and rising food prices, agriculture and food security has been affected worldwide. Cereal grains being a major part of world food supply also act as important energy source in human diet. In order to counter food insecurity, alternative grains are being explored, and millet being drought-resistant has the potential to serve as an alternative grain due to its comparable nutritional composition with other major cereals and its gluten free proteins. The evidence that gluten sensitivity is one of the increasing food intolerances is driving an increasing demand for gluten-free foods. However, gluten …

Effect Of Phytosanitary Irradiation And Methyl Bromide Fumigation On The Physical, Sensory, And Microbiological Quality Of Blueberries And Sweet Cherries, Karen Thang, Kimberly Au, Cyril Rakovski, Anuradha Prakash

Food Science Faculty Articles and Research

Background

The objective of this study was to determine whether irradiation could serve as a suitable phytosanitary treatment alternative to methyl bromide (MB) fumigation for blueberries and sweet cherry and also to determine the effect of phytosanitary irradiation treatment on survival of Salmonella spp. and Listeria monocytogenes on these fruit. ‘Bluecrop’ blueberries (Vaccinium corymbosum) and ‘Sweetheart’ cherries (Prunus avium) were irradiated at 0.4 kGy or fumigated with methyl bromide and evaluated for quality attributes during storage.

Results

Irradiation caused an immediate decrease in firmness of both fruit without further significant change during storage. Fumigated fruit, in …
