“…On the other hand, the results of those studies are higher than those reported in Venezuela, where a 2% frequency for raw shrimp was reported (29). In addition, other studies have also reported prevalence rates of 1.8% a 5.71% in shrimp (29,(30)(31)(32), which are much lower than our results (64.1%).…”

Introduction: Multidrug-resistant (MDR) pathogenic bacteria in seafood, especially shrimp and octopus, are significant public health concerns and are able to be transmitted to humans in foodstuffs, particularly when they are of animal origin. The present study was conducted to measure the antimicrobial susceptibility patterns and prevalence of Salmonella isolates obtained from octopus and shrimp in San Francisco de Campeche, Mexico. Methods: Two hundred shrimp and octopus samples (one hundred each) were collected from the municipal market, and each sample consisted of 100 g. The present study used conventional methods to identify and isolate Salmonella, with the disk-diffusion method used to screen all isolates for sensitivity to 12 antibiotics. Results: The prevalence of Salmonella was found to be 56% and 45% in shrimp and octopus, respectively. The high levels of Salmonella observed in the municipal market sampled by the present study reveal poor sanitary conditions in the processing and transport of the products of interest and those handling them at the point of sale. All the Salmonella strains were resistant to at least three antimicrobial classes. All shrimp isolates (100%) presented susceptibility to chloramphenicol and the majority (88%) presented sensitivity to ciprofloxacin, while the strains isolated in the octopus individuals sampled presented sensitivity to both the foregoing antibiotics (74% and 90%, respectively). Conclusion: Based on the high prevalence in the samples analyzed, our results suggest that shrimp and octopus could be involved in Salmonella infections in the population.

BackgroundFish is a possible source of foodborne infections with Salmonella and Escherichia coli. This study was conducted to identify Salmonella and E. coli along the fish value chain in Bahir Dar City, Ethiopia.MethodsA cross‐sectional study was undertaken with purposive sampling. A total of 121 specimens comprising fresh fish, retailing fish, filleted and cooked fish, swabs, and water samples were collected. Both culture based and molecular methods were used for detection.ResultsE. coli isolated from 41 (33.88%) and Salmonella from 6 (4.96%) specimen. The highest E. coli isolation rate was from retailing fish 16 (80%), whereas the highest Salmonella isolation rate from filleted tissue 2 (20%). At restaurants, 12 (30%) samples were positive for E. coli and 3 (7.50%) for Salmonella. All 41 E. coli isolates were resistant to amoxicillin/clavulanate, whereas no resistance was shown for gentamicin and amikacin. Two thirds of Salmonella isolate and 95.12% of E. coli were detected as they develop multidrug resistance. The highest rate of resistance was recorded for ceftazidime against all (n = 6) isolates of Salmonella species. From a total of 10 E. coli isolates tested by PCR, 4 were positive for hemolysin A1 and/or eae virulence genes.ConclusionsThe study detects the potential biological hazards along the value chain. Hygiene of fish handlers and their working environment and proper fish cooking are highly valuable. One health campaign should be carried out on drug resistance, contamination of the lake, and fish safety.

Salmonella spp. in the fish production chain: a review

et al. 2018

View full text Add to dashboard Cite

Salmonella spp is a pathogen responsible for severe foodborne infections, can be introduced into the fish production chain through inadequate handling or hygiene or contact with contaminated water, and is not a biological contaminant originally reported in fish. Fish microbiological safety is a concern for consumers, industries and regulatory agencies worldwide, since fish, an important food category in the international trade and often exported to several countries, can act as a vehicle for Salmonella transmission throughout the production chain. In addition, concerns regarding the misuse of antibiotics in aquaculture are also an issue, as a result of the increased isolation of resistant and multiresistant Salmonella serovars. In this review, we examined aspects associated with the microbiological risks of the presence of Salmonella spp. in fish and their implication in the aquaculture production chain. In addition, incidence and antimicrobial resistance data are presented, as well as strategies for Salmonella prevention and control in fish.
