HACCP Assessment of Virginia Meat and Poultry Processing Plants
MetadataShow full item record
During these audits, two microbial determination methods (Standard Plate Count and Bioluminescence) were used to evaluate processing equipment. Typically, three pieces of equipment were tested at each plant. When the data were collected, the two microbial determination methods were correlated. The "corr" function in SAS resulted in a correlation coefficient of .4478, which is low and indicates a poor correlation. A pass/fail method similar to one done by Illsley et. al. resulted in a 48.9% agreement between the methods in this research.
