Assuming that the various phage types of Salmonella Enteritidis (S. Enteritidis) are largely equally virulent, the importance of certain foods as sources of infection for human salmonellosis can be deduced from differences in the distribution of phage types in human and non-human samples. In 2002, S. Enteritidis phage type 29 (PT29) was first isolated from non-human test samples in Austria. S. ...

Consumers believe that quality of foods from organic production is superior to foods from conventional production. The objectives of the present study have therefore been to compare the quality of chicken meat from organic and conventional production on the basis of traditional meat quality criteria. The experiment was organized as a field study. Fresh organic broiler carcasses were purchased d...

Our primary objective was to improve on an existing model for the individual weekly egg production curve by modeling the curve as a sum of logistic functions: one for the increasing phase of production and a sum for the decreasing phases. To illustrate the model, we used four data sets from two pairs of individuals. For these data, the model consisted of an increasing phase and a single decreas...

Voluntary control of attention promotes intelligent, adaptive behaviors by enabling the selective processing of information that is most relevant for making decisions. Despite extensive research on attention in primates, the capacity for selective attention in nonprimate species has never been quantified. Here we demonstrate selective attention in chickens by applying protocols that have been u...

ABSTRACT To ensure that chicken meat products are safe to consume, it is important to be able to reliably determine its shelf-life. To assess the applicability of ultra-fast gas chromatography and electronic nose technology in evaluation of poultry, an analysis of the headspace of ground chicken meat samples refrigerated over a period of 7 days was performed. Chemometric techniques were used to...

The aim of this study was to develop a polymerase chain reaction (PCR) protocol for the detection of Salmonella in artificially contaminated chicken meat. Tests were performed with different dilutions of Salmonella Typhimurium or Salmonella Enteritidis cells (10(-7), 10(-8) or 10(-9) CFU/mL) inoculated in chicken meat samples, in order to establish the limits of detection, incubation times (0, ...

Effects of antioxidants butylated hydroxytoluene (BHT, 0.02%), carnosine (1%), and plant extracts rosemary (RE, 1%), pine bark (PBE, 1%) pomegranate (PGE, were investigated on total plate counts, pH, color, lipid oxidation (LPO) in chicken breast meat patties packed modified atmosphere treated with dielectric-barrier-discharge (DBD) cold plasma (CP). The effect mesophilic inactivation (> 50% re...

The detection of enterotoxigenic Escherichia coli (ETEC) in food, especially raw meat, has rarely been documented in Thailand, although the presence of this bacterial pathogen is considered of important public health concern. The quantity of ETEC in 150 meat samples collected from fresh food markets in southern Thailand were determined using a most probable number (MPN)-PCR-based quantification...

A cross-sectional study was performed to estimate the prevalence of Salmonella on retail market chicken carcasses in Colombia. A total of 1,003 broiler chicken carcasses from 23 departments (one city per department) were collected via a stratified sampling method. Carcass rinses were tested for the presence of Salmonella by conventional culture methods. Salmonella strains were isolated from 27...

Chicken meat is the most preferential consumable edible nowadays. The present increased demand and supply of the chicken has resulted in the provision of chicken feed supplemented with all the basic macro and micronutrients to the poultry. As the consequence enhanced weight gain and growth of the chickens is observed that has allowed them to attain appropriate weight and size for consumption in...
