Listeriosis is a foodborne disease caused by Listeria monocytogenes. Because outbreaks of listeriosis are associated with the ingestion of contaminated dairy products, surveillance of artisanal cheeses to detect the presence of this microorganism is necessary. We collected three types of artisanal non-acid fresh cheese (Campesino, Costeño, and Cuajada) from 12 municipalities of the Department of Quindío, Colombia. L. monocytogenes was identified using VIDAS® and confirmed with API® Listeria Rapid Kit. L. monocytogenes was detected in 104 (53.6%) of the 194 artisanal fresh-cheese samples analyzed. The highest percentages of contamination were detected in Salento (90.9%), Calracá (65.5%), Armenia (64.9%), and Filandia (50%). A significant association between municipality and contamination with L. monocytogenes was identified. However, no association could be established between the type of cheese and the occurrence of the bacterium. This is the first study on the presence of L. monocytogenes in artisanal fresh cheeses sold in the municipalities of the Department of Quindío, and the findings revealed very high percentages of contaminated samples. The presence of L. monocytogenes in artisanal cheeses remains a public health threat in developing countries, especially Colombia, where existing legislation does not require the surveillance of L. monocytogenes in food.

Abstract Background Electrical and electronic waste or e-waste is emerging as a major public health threat worldwide because of rapid advances in technology leading to the generation of large amount of wastes and a lack of knowledge in handling of these wastes. Objective The current review discusses the current e-waste problem worldwide, as a public health concern, with a specific focus on India and recommendations to have effective e-waste management. Methods This is a traditional review study. The burden of e-waste, regulations and its impact on health and the environment at the global and country level were identified using various search engines such as PubMed, Google Scholar, Scopus and ScienceDirect. Books, case studies, legislation documents, reports, original articles and other documents from international organizations and specific governmental agency websites were retrieved. In total, 33 original articles, reports, case studies and documents were used for this review. Results In 2016, 44.7 million tonnes of e-waste was generated with 2 million tonnes produced in India alone. Out of this, only 20% of the e-waste generated globally was handled properly. The situation is worse in India where more than 90% of the e-waste was handled by informal sector workers. An important problem with the process is that they do not take necessary precautionary measures before handling e-waste. Components which are not suitable for reuse are burnt openly or disposed of through open dumping. Most of the informal sector workers are illiterate making them unaware of the hazardous chemicals that can be released later into the water sources and the environment. Conclusion The current review shows that the e-waste poses a serious global public health threat leading to significant environmental and health risks. Most of the developing countries including India were found to be lagging behind in the implementation of environmentally sound formal recycling processes. Hence, a better life cycle assessment model which have been successfully implemented in other developing countries should be introduced in India.

Examination of 227 samples of milk and dairy products for Listeria monocytogenes showed that raw milk and some Moroccan traditionally made dairy products such as Iben and raib (fermented milks) and jben (fresh cheese) were contaminated with this pathogen. L. monocytogenes was the only Listeria species isolated except in one case in which it was associated with Listeria innocua. Pasteurized milk, fresh cream, and fresh and ripened cheeses (industrially made) were free from L. monocytogenes.
