Plant Processing of Sub-atmospheric Steam Scalded Poultry

Salmonella contamination in a poultry-processing plant.

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...

Airborne Campylobacter in a Poultry Processing Plant

Campylobacter is a foodborne pathogen commonly found in live poultry and raw poultry products. Identifying areas of contamination or modes of transmission during commercial processing can lead to strategies to reduce the level of Campylobacter on finished products. Monitoring levels of airborne Campylobacter may be useful for identifying the presence or relative concentration of the pathogen in...

Superheated Steam Drying at Atmospheric Pressure

Steam versus hot-water scalding in reducing bacterial loads on the skin of commercially processed poultry.

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 ...

Linear Identification of a Steam Generation Plant

The paper examines the development of models of steam generation plant using linear identification techniques. The identification process is carried out using experimental data of a multi-input multi-output MIMO system representation. Various techniques of modeling and identification are applied considering the complete system as a MIMO model and studying the effect of all the inputs on individ...
