Chicken Eggs

Chicken eggs are a staple food for humans and are consumed all over the world. Chicken eggs have a leading position among food products in terms of nutritional value and taste. During storage, under the influence of air oxygen and microorganisms, eggs deteriorate, contamination of opportunistic and pathogenic microflora increases. Purpose: analysis of the results of bacteriological studies of eggs of various producers during automatic and manual sorting and packaging from the trading network in Sumy and the Sumy region in accordance with DSTU 5028:2008 “Edible hen eggs. Specifications” and Microbiological Criteria for Establishing Food Safety Indicators. Materials and methods. Bacteriological studies of shell washings and egg contents were carried out according to standard methods. Samples of edible chicken eggs with automatic and manual sorting and packaging corresponded to DSTU 5028:2008, Microbiological criteria for establishing food safety indicators and BIE No. 5061-89. Pathogenic and opportunistic pathogens of bacterial diseases were not isolated from the surface of eggs of the control group during automated sorting and packing, spore bacteria of the genus Bacillus (Bacillus subtilis) were isolated. In washes from the egg shell surface with manual sorting and packaging, Streptococcus spp was found – 12 % of the number of samples examined, E. faecalis – 34 %, P. aeruginosa – 11 %, and spore bacteria of the genus Bacillus (B. subtilis) – 43 %. The number of QMA&OAMO and CGB (coli-forms) in both groups corresponded to the established norms, but the QMA&OAMO indicator in the products of enterprises with manual collection and packaging was 34 % higher compared to eggs from enterprises with automated sorting and packaging. Automation of the process of sorting and packing eggs provides the best microbiological indicators of the safety of edible hen eggs in comparison with those when using manual labor during sorting and packing. A complete transition to the automation of production processes for the production of edible eggs in Ukraine is required.

A new technology based on bio-templating approach was proposed in this paper. Egg-shell membrane (ESM) has been employed as a natural biotemplate. Fibrous oxide ceramics was prepared by wet impregnation of biological template with water solution of cerium nitrate. The template was derived from membranes of fresh chicken eggs. Repeated impregnation, pyrolysis and final calcination in the range of 600 to 1200?C in air resulted in template burnout and consolidation of the oxide layers. At low temperatures, the obtained products had structure which corresponded to the negative replication of biological templates. Unique bio-morphic CeO2 microstructures with interwoven networks were synthesized and characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD), whereas low-temperature nitrogen adsorption (BET) method was used in order to characterize porous properties.

The interest for natural antimicrobial compounds has increased due to alterations in consumer positions towards the use of chemical preservatives in foodstuff and food processing surfaces. Bacteriophages fit in the class of natural antimicrobial and their effectiveness in controlling bacterial pathogens in agro-food industry has led to the development of different phage products already approved by USFDA and USDA. The majority of these products are to be used in farm animals or animal products such as carcasses, meats and also in agricultural and horticultural products. Treatment with specific phages in the food industry can prevent the decay of products and the spread of bacterial diseases and ultimately promote safe environments in animal and plant food production, processing, and handling. This is an overview of recent work carried out with phages as tools to promote food safety, starting with a general introduction describing the prevalence of foodborne pathogens and bacteriophages and a more detailed discussion on the use of phage therapy to prevent and treat experimentally induced infections of animals against the most common foodborne pathogens, the use of phages as biocontrol agents in foods, and also their use as biosanitizers of food contact surfaces.

In present study, the occurrence of Salmonella in local chicken eggs and their pattern of antibiotic resistance were determined. 100 egg samples collected from different locations of Dhaka city were analysed and Salmonella spp were found in 8% of the samples. Among all presumptive Salmonella isolates, 8 isolates were confirmed as Salmonella enterica subsp. salamae (4%), Salmonella enterica subsp. indica (1%), Salmonella Paratyphi-A (1%), Salmonella bongori (1%) and Salmonella Choleraesuis (1%) on the basis of serotyping and biochemical analysis. These isolates were subjected to susceptibility test against 10 antibiotic disks. All the isolates were found chloramphenicol sensitive. The highest percentage of resistance (87.5%) was found to amoxicillin and ampicillin. Resistance against erythromycin, cephalexin, doxycycline hydrochloride, ceftazidime, doxycycline and nalidixic acid was also found significant ranging from 25% to 62.5%. Salmonella isolated from egg shell surface were found more antibiotic resistant than that of egg yolk and white. The present study suggests that poultry eggs are potential reservoir of antibiotic resistant Salmonellae.Keywords: Egg; Salmonella; Characterization; Antibiotic resistance.© 2011 JSR Publications.

The purpose of research is increase of beef productivity and beef quality of Simmental calves at introduc-tion in a diet of feeding different doses of the drug Vetosporin suspension. Of the half-yearly animals, 40 males were selected and formed into group IV for the experiment. The differences were only in feeding. The young were fed the studied additive Vetosporin suspension. In this case, the supplement was an addi-tion to the basic diet of animals of the experimental II-IV groups. The volume of the additive added was 0.1; 1.0; and 2 ml per 10 kg of live weight, respectively. Control group I, consumed exclusively a diet that does not contain an additive. Based on the results of the experiment at the age of 18 months. The prevalence of bulls of the experimental live weight over peers was observed, which was 4.4-25.3 kg (0.78-4.67%). The study of the studied indicators after control slaughter in the context of groups showed the superiority of bulls of experimental groups in all the periods studied. It is established that at the age of 15 months. The size of the removable live weight of the youngest of the control group was less by 8.0-19.7 kg (1.75-4.29%) than in the animals of the test groups. In this case, the leading position was occupied by the youngest of group III, the prevalence of which was 0.7-11.7 (0.14 -2.51%). It should be noted that after 3 months a simi-lar picture of the distribution of the studied quantities was observed. As for the output of carcass, we can note the following. Outsider among the animals of the experimental groups was the control group. So the bulls of group I were inferior to those who received the additive by 0.7-1.3%. At 18 months, as well as at 15 months, the dominant position was occupied by gobies of experimental groups. It should be noted that among the animals of the experimental groups the leading place was occupied by the bulls receiving the feed additive in a dose of 1.0 ml per 10 kg of live weight, that is, the youngest of the III group.

The article presents the results of the effect of partial replacement of mixed feeds with organic concentrate based on dry bird droppings (DBD) on the preservation of quail, quantitative and qualitative rates of egg productivity. For the laboratory experiment, 5 experimental groups of Manchurian quail were formed by the analogous pair comparison method. The quail of the control group consumed all-in-one feed (AF), for the quail of the experimental groups (I, II, III, and IV) part of the AF – 10, 15, 20 and 25 % by weight – was replaced with organic concentrate. Results of studies reveal that the introduction of 10 % of organic concentrate into the AF contributed to improved feed intake and livestock safety, increased egg productivity and reduced feed consumption per unit of output. With respect to the indicators of biological usefulness, toxicological and sanitary-epidemiological safety, quail eggs treated with the organic concentrate met the requirements of GOST and TR TS 021/2011 “On food safety”.

Poultry Farming

Compound feed are subject to requirements for their composition, since they use several types of grains that contain anti-nutritive substances that reduce the digestibility and use of nutrients. One of the tasks of domestic poultry farming is to reduce losses by increasing the digestibility and accessibility of feed. Among the most effective ways to solve this problem is to add enzymes to the feed of poultry. The inclusion of enzyme drugs in the composition of compound feed contributes to the inactivation of anti-nutritive substances, which contributes to an increase in the coeffi cient of digestibility of nutrients. The purpose of the work was to establish the feasibility and eff ectiveness of the enrichment of compound feed used in the production technology of chicken eggs with mixtures of enzyme drugs of domestic production of Amylosubtilin G3x, Cellolux-F and Protosubtilin G3x. Three groups of laying hens with 57 heads in each have been formed: a control group and two experimental groups. The duration of the experiment was 420 days. Laying hens of the control group have been received farm compound feed depending on their age. Laying hens of the 1st experimental group have been received compound feed of the control group enriched with the enzymes Amylosubtilin G3x and Cellolux-F depending on the age. In the compound feed of laying hens of the 2nd experimental group enzyme drugs were additionally introduced depending on the age Amilosubtilin G3x and Protosubtilin G3x. Higher egg production rates have been observed in the 1st experimental group – 357,81 eggs, which was 6,48 % higher than in the control group and 1,84 % higher than in the 2nd experimental group. The weight of eggs of laying hens of the 1st experimental group was 1,85 g or 2,97 % more, and the 2nd experimental group was 0,7 g or 1,12 % more than in the control group. The diff erence between the egg weight in laying hens of the 1st and 2nd experimental groups was 1,85 % or 1,15 g. The lowest feed consumption of 1,37 kg for the production of 10 eggs was in the laying hens of the 1st experimental group, which was less than the indicator of the control group by 10,94 and by 4,2 % than in the 2nd experimental group.

The article presents the results of evaluating the effect of detergent and various disinfectants used for sanitary treatment of the surface of egg shells of hen edible on their quality and safety indicators. Four disinfectants belonging to different groups of drugs were selected for research: «SUNWAY DES» (peroxide), «Silversil Des» (silver-containing), «Lanex» (quaternary-ammonium compounds), «Catelon 502» (containing peracetic acid). A decrease of the mass of all samples of eggs during the whole storage period (35 days) 5,6–6,6% of initial, was increasing the height of the air chamber eggs 2,3–2,9 times, with the largest increase was in specimens treated by «Silvercel Des» and «Lanex». The decrease in egg density in salt solution was at the same level in all experimental samples. There was a decrease in the yolk index by 7,7% in the control sample and by 16,3–19,0% in the experimental samples, but the yolk shell did not break in all cases. By the end of the shelf eggs life, the shell thickness and elastic deformation met the requirements. According to microbiological indicators, all egg samples during 33 days of storage met the requirements of the technical normative legal acts. Organoleptic evaluation of eggs at 16 and 35 days of storage allowed us to establish that the best, closest in organoleptics to the eggs of the control group, were the eggs of the 1st experimental group, and the worst, according to the conclusion of the majority of tasters, were the eggs of the 3rd experimental group. Based on a comprehensive analysis of the research, it was found that «SUNWAY DES» and «Catelon 502» disinfectants can be recommended for disinfecting the surface of the egg shell of edible hen eggs.

Purpose – The purpose of this paper is to create a series of 30-60-second short videos to promote improved food safety behaviors of middle school youth, determine the feasibility of disseminating the videos through peer networks, and measure their effects on food safety attitudes, perceived social norms, and behaviors of youth. Design/methodology/approach – Food safety content specialists, learning experts, programmers, illustrators, project managers, instructional designers, scriptwriters, and stakeholders were involved in creation of the Don’t Be Gross short videos before evaluation by middle school youth (sixth to eighth grades). The experimental group (n=220) completed the following activities at about one-week intervals: pre-test, viewed videos, post-test, and follow-up test. The control group (n=112) completed the same activities at similar intervals but did not have access to the videos until after the follow-up test. Findings – Controlling for grade and gender, linear mixed-effects models revealed significant time by group effects for participants’ perceived susceptibility to foodborne illness; intentions to perform recommended food safety behaviors approached significance. Additionally, compared to the pre-test, the experimental group perceived their friends as being significantly more confident in performing food safety behaviors at post- and follow-up tests. Google Analytics data revealed that the bounce rate from the home page of the videos was low (38 percent) suggesting that the videos were engaging. Originality/value – The Don’t Be Gross videos were liked by youth and shared among their peers and may have the potential to promote positive food safety behaviors and intentions among youth.
