“…Recently, Chahouri et al [ 47 ] conducted a similar microbiological investigation in the Agadir Bay (Morocco), performing the search and AMR characterisation of Vibrio and Salmonella strains from mussels, sediment, and water samples. In accordance with our results, they isolated Vibrio strains at a high frequency, while a low percentage was noted for Salmonella .…”

The emergence of antimicrobial resistance (AMR) is increasingly common across the globe and aquatic ecosystems could be considered a reservoir of antibiotic-resistant bacteria. This study aimed to determine prevalence and antibiotic susceptibility of the potential pathogenic bacteria Salmonella spp. and Vibrio spp. in bivalve molluscs intended for human consumption, collected over a period of 19 months along the northern coast of Apulia region. The AMR profile was also determined in non-pathogenic Vibrio species, common natural inhabitants of seawater and a useful indicator for the surveillance of AMR in the environment. The current study presents data on the AMR of 5 Salmonella and 126 Vibrio isolates by broth microdilution MIC. Multidrug resistance (MDR) was observed in one S. Typhimurium strain towards sulfamethoxazole, trimethoprim, tetracycline, gentamicin, and ampicillin and in 41.3% of the Vibrio strains, mostly towards sulphonamides, penicillin, and cephems. All Vibrio isolates were sensitive to azithromycin, chloramphenicol, tetracycline, amoxicillin/clavulanic acid, gentamicin, streptomycin, amikacin, and levofloxacin. The AMR phenomenon in the investigated area is not highly worrying but not entirely negligible; therefore, in-depth continuous monitoring is suggested. Results concerning the antibiotic agents without available specific clinical breakpoints could be useful to upgrade the MIC distribution for Vibrio spp. but, also, the establishment of interpretative criteria for environmental species is necessary to obtain a more complete view of this issue.

“…Most regulatory agencies use the fecal indicator bacteria, including fecal coliforms, enterococci, or Escherichia coli , which fail in evaluating human pathogenic Vibrio spp. pollution, such as V. parahaemolyticus (Chahouri et al., 2022). Therefore, the developments of standard and effective human pathogenic Vibrio spp.…”

Vibrio spp., known human foodborne pathogens, thrive in freshwater, estuaries, and marine settings, causing vibriosis upon ingestion. The rising global vibriosis cases due to climate change necessitate a deeper understanding of Vibrio epidemiology and human transmission. This review delves into Vibrio contamination in seafood, scrutinizing its sources and pathways. We comprehensively assess the contamination of human‐pathogenic Vibrio in the seafood chain, covering raw materials to processed products. A “Farm‐to‐Fork” approach, aligned with the One Health concept, is essential for grasping the complex nature of Vibrio contamination. Vibrio’s widespread presence in natural and farmed aquatic environments establishes them as potential entry points into the seafood chain. Environmental factors, including climate, human activities, and wildlife, influence contamination sources and routes, underscoring the need to understand the origin and transmission of pathogens in raw seafood. Once within the seafood chain, the formation of protective biofilms on various surfaces in production and processing poses significant food safety risks, necessitating proper cleaning and disinfection to prevent microbial residue. In addition, inadequate seafood handling, from inappropriate processing procedures to cross‐contamination via pests or seafood handlers, significantly contributes to Vibrio food contamination, thus warranting attention to reduce risks. Information presented here support the imperative for proactive measures, robust research, and interdisciplinary collaboration in order to effectively mitigate the risks posed by human pathogenic Vibrio contamination, safeguarding public health and global food security. This review serves as a crucial resource for researchers, industrials, and policymakers, equipping them with the knowledge to develop biosecurity measures associated with Vibrio‐contaminated seafood.

“…[1][2][3][4][5][6] Mycobacterium tuberculosis, Staphylococcus, Salmonella, Escherichia coli, and Bacillus anthracis are known to be the deadliest bacteria. [7][8][9][10][11] It is predicted that more than 10 million people will succumb to bacterial infection in the following 30 years if we do not take any measures to deal with antimicrobial resistance (AMR). 12 Therefore, it is urgent to find some new broad-spectrum antibacterial agents that can effectively overcome drug-resistant bacterial infections.…”
