Determinación de Listeria monocytogenes en quesos blancos artesanales expendidos en la plaza de mercado de Cáqueza, Cundinamarca

Food poisoning is a public health problem, because it can show up in any population being more prevalentin people whose immune system is compromised, pregnant women, and the elderly. According to the obtaineddata, 80% of the positive results for Listeria spp showed Listeria monocytogenes and 20% presented Listeriainnocua. This indicates a prevalence of the pathogenic species for humans, thus augmenting the risk forpeople to suffer from gastrointestinal and/or systemic disease especially in the population mentioned above.In the same way, it was determined that 100% of the cheese showed some microbial contamination. Informationabout the cheese elaboration and storing processes was collected and, in the same way, the manner food washandled in stores was observed.
