Abstract
A database of condemnation data from abattoirs was combined with a meteorological database to investigate the relationship between the prevalence of pleurisy and pneumonia in pigs in Northern Ireland and prevailing weather conditions. Between 1969 and 1989 three significant trends were found in the occurrence of condemnations due to pleurisy and pneumonia, and significant correlation coefficients were found between the percentage condemnations and air temperature.
