Gallego Marín, Manuel Isaac | 2005-07

Listeria monocytogenes is a pathogenic mocroorganism recognized as the cause of health problems in humans and animáis, mainly originated by ingestión of contaminated meat and dairy producís. (Jp to now, no studies in order to determine carease infection grades of bovines have been carried out in Colombia, therefore, the objetive of this research was to establish its presence in Holstein careases, since this breed is a population of high infection risk. From a population of 1600 careases, 133 were examined and only three (2.26%) were found positive to Listeria monocytogenes. This type of meat is mainly consumed by the population with lower incomes, which combined with other risk factors, may constitute a very serious public health problem.
