View article: Evidence for the efficacy of pre-harvest agricultural practices in mitigating food-safety risks to fresh produce in North America
Evidence for the efficacy of pre-harvest agricultural practices in mitigating food-safety risks to fresh produce in North America Open
Consumption of contaminated produce remains a leading cause of foodborne illness. Increasingly, growers are altering agricultural practices and farm environments to manage food-safety hazards, but these changes often result in substantial …

Role of soil in the regulation of human and plant pathogens: soils' contributions to people Open
Soil and soil biodiversity play critical roles in Nature's Contributions to People (NCP) # 10, defined as Nature's ability to regulate direct detrimental effects on humans, and on human-important plants and animals, through the control or …

Bather Shedding as a Source of Human Fecal Markers to a Recreational Beach Open
Microbial source tracking (MST) can identify and locate surf zone fecal indicator bacteria (FIB) sources. However, DNA-based fecal marker results may raise new questions, since FIB and DNA marker sources can differ. Here, during 2 years of…

Cascading effects of composts and cover crops on soil chemistry, bacterial communities and the survival of foodborne pathogens Open
Aims Recent foodborne disease outbreaks have caused farmers to re-evaluate their practices. In particular, concern that soil amendments could introduce foodborne pathogens onto farms and promote their survival in soils has led farmers to r…

Hospital Effluents Are One of Several Sources of Metal, Antibiotic Resistance Genes, and Bacterial Markers Disseminated in Sub-Saharan Urban Rivers Open
Data concerning the occurrence of emerging biological contaminants such as antibiotic resistance genes (ARGs) and fecal indicator bacteria (FIB) in aquatic environments in Sub-Saharan African countries is limited. On the other hand, antibi…

Metal Distribution and Characterization of Cultivable Lead-Resistant Bacteria in Shooting Range Soils Open
Shooting ranges represent about 10% of polluted sites in Switzerland. This pollution, mainly consisting of lead (Pb) and antimony (Sb), can spread into the local groundwater, wildlife and plants. In this study, shooting range stop butt soi…

Occurrence of Antibiotic Resistance Genes and Bacterial Markers in a Tropical River Receiving Hospital and Urban Wastewaters Open
The occurrence of emerging biological contaminants including antibiotic resistance genes (ARGs) and Faecal Indicator Bacteria (FIB) is still little investigated in developing countries under tropical conditions. In this study, the total ba…

Exploring research frontiers in aquatic ecosystems: role of hospital and urban effluents in the dissemination of antibiotic resistance and metals to fresh water ecosystems Open
Since the middle of the 20th century, pollution of freshwater resources by anthropogenic activities constitutes major sources of aquatic environment contamination. In the recent past research is documenting on the prevalence of emerging co…
