Bacteriological safety and quality of composted products from animal, urban or sewage sludge wastes.

This study investigated the presence of culturable bacterial pathogens, and antibiotic resistance and associated genes (quantitative PCR) in commercially available composted products from animal excrements or manure (n = 7), urban wastes (n = 1) or (sewage sludge) (n = 1). Metals quantification and 16S rRNA-based bacterial community composition analyses supported the results to infer potential risks to downstream environments (e.g.
