The health and safety of seafood is a global concern. The prevalence of antimicrobial resistance and heavy metal contamination has adverse consequences for consumer health. The aim of the present study was to investigate Escherichia coli contamination and antibiotic resistance of isolates and to determine lead and cadmium in farmed and wild shrimp supplied in Bandar Abbas. 60 farmed and marine shrimp samples were sampled from the Bandar Abbas market and transferred to the laboratory. The linear culture method was used to isolate Escherichia coli, the Disk Diffusion method was used to determine antibiotic resistance, and the atomic absorption spectrometer was used to determine heavy metals. The results of the investigation of microbial contamination in farmed and marine shrimp showed that out of a total of 60 shrimp samples, 9 samples were contaminated with Escherichia coli. Thus, the level of Escherichia coli contamination in marine shrimp was 7 samples (11.66%) and farmed shrimp was 2 samples (3.33%), and the highest antibiotic resistance was related to sulfamethoxazole (100%) and tetracycline (88.88%) and the lowest resistance was related to imipenem (0). The results of the heavy metal assessment showed that the level of contamination in marine shrimp with lead and cadmium was higher than in farmed samples. Our results showed that marine and farmed shrimp are sources of Escherichia coli contamination and in terms of heavy metals, strict decisions should be made regarding the release of industrial waste and other sources of contamination.
