This study evaluated the ability of Campylobacter jejuni to penetrate through the pores of the shells of commercial eggs and colonize the interior of these eggs, which may become a risk factor for human infection. Furthermore, this study assessed the survival and viability of the bacteria in commercial eggs. The eggs were placed in contact with wood shavings infected with C. jejuni to check the...

Seventy-three billion chicken eggs are produced annually in the United States. However, less than 0.1% of these eggs are exported. Increasing the shelf-life of eggs may increase export sales. The goal of this research was to determine whether food-grade coatings on eggs may extend shelf-life under refrigerated storage. Four food-grade coatings were selected: paraffin wax, mineral oil, soy prote...

The study was conducted to determine the absorption of essential and non-essential trace minerals from poultry feed products. Poultry feed, liver, muscles, egg samples were collected six farms in Rawalpindi Islamabad. Mercury, Lead, Cadmium, Chromium, Iron analyzed using Inductively Coupled Plasma Optical Emission Spectrophotometer. Iron, Chromium exceeded permissible limits set by World Health...

Kecent trends in research in the field of egg quaUty have been toward the study of the initial condition of the egg rather than the changes that occur during holding periods under varying environmental influences. Most investigators have concerned themselves largely with the so-called interior egg-quality characters and more particularly with the albumen portions of the egg. Practically all suc...

Eggs were collected from a single inline processing facility weekly for 3 wk (replicates). The eggs were stored at 4 degrees C and 80% RH. Sampling began the day after collection and continued each week for 10 wk. During analysis, 24 eggs were examined for egg weight, albumen height, Haugh units (HU), shell strength, and vitelline membrane strength for each replicate. Egg weight decreased (P < ...

Mercury contamination of wildlife populations has been documented widely in recent years as biomonitoring has become an important tool for assessing environmental contamination. Avian eggs provide an ideal assay material for Hg biomonitoring, particularly when the collection of eggs is simplified by using cavity-nesting species that nest in easily monitored nest boxes. However, studies are need...

(Extended photo media series ; 2) On cover: The history and practice of photographic printing, 1840-1895. Preface Silverprinting has been often doomed, but it still survives. The Albumen and Salted Paper Book is a book about the major photographic printing processes in use during the years 1840-1895, approximately the first half-century of photographic history. These first 50 years of photograp...

The aim of the performed investigations was to compare eggs of Japanese quail layers of different weights with regard to their shape, selected traits of the content following various times of their storage as well as the results of hatchability and body weight of one-day old chicks. Hatching eggs were divided into four groups: group S – up to 10.50 g, group M – from 10.51 to 11.50 g, group L – ...
