A comparison of two types of scalders was conducted to determine their effectiveness in reducing bacterial contamination of poultry carcasses. A conventional hot-water scalder and a prototype model of a steam scalder were tested under commercial conditions. Total plate counts from steam-scalded birds were significantly lower than the counts of water-scalded birds immediately after scalding and ...

Bacteriological examination of 1,427 samples from a poultry-processing plant over a 2-year period yielded 202 (14.2%) cultures positive for salmonellae. The results indicate that contamination is reduced by washing procedures within the plant but that recontamination of the carcasses occurred in at least two different stages of processing, i.e., during evisceration and chilling. There was evide...

The main aim of this study was to trace Campylobacter subtypes colonizing Italian broilers and carcasses in and between flocks. Overall, 209 Campylobacter isolates were collected from ceca (n = 94) and carcasses (n = 115) of broilers belonging to 3 different flocks reared in the same farm during subsequent rotations and processed in the same slaughterhouse. All isolates were identified by multi...

An integral component in preventing an avian influenza pandemic is containment and disposal of infected bird (poultry) carcasses. Disposal of carcasses in Subtitle D municipal solid waste (MSW) landfills may be an advantageous option due to their large capacities and facility distribution in the U.S. In this study, the survival of H6N2 avian influenza virus (AIV) was measured in a methanogenic ...

Approximately 2.2million cattle carcasses require disposal annually in the United States. Land burial is a convenient disposal method that has been widely used in animal production for disposal of both daily mortalities as well as during catastrophic mortality events. To date, greenhouse gas production after mortality burial has not been quantified, and this study represents the first attempt t...

The objective of this study was to evaluate effects of age, sex, and postmortem carcass aging duration on parts yield from broiler chickens. Two hundred twenty-four mixed-sex broilers were reared under commercial-like conditions for various periods between 37 and 51 d, slaughtered, packed in ice, and then aged for 0, 2, 4, or 6 h. Mean percentage yield of thighs, drumsticks, forequarters, wings...

Abstract Introduction Campylobacteriosis is the most common human foodborne bacterial infection worldwide and caused by bacteria of Camplylobacter genus. The main source these poultry, but other food-producing animals such as pigs are also responsible for infections. An increasing number strains with resistance to fluoroquinolones antimicrobials macrolides were recently noted. aim study was inv...
