Abstract

GONCALVES, Magda et al. The Presence of Listeria monocytogenes in Soft Cheeses from the Southern Region of Tejo. Port J Public Health [online]. 2017, vol.35, n.1, pp.37-43. ISSN 2504-3137.  http://dx.doi.org/10.1159/000477648.

Introduction: In the past decades, the number of food poisoning outbreaks brought on by Listeria monocytogenes has been increasing. Methods: We analyzed 30 samples of soft cheeses from different manufacturers, of which 66.7% were produced from raw sheep milk. Results: The presence of L. monocytogenes was detected in 10% (n = 3) of the analyzed samples, and 17% (n = 5) were contaminated with L. innocua. Conclusion: The consumption of soft cheeses is associated with an increased risk of listeriosis.

Keywords : Listeria monocytogenes; Listeriosis; Cheese; Public health; Foodborne outbreak.
