Superbugs in your shrimp: Deadly colistin-resistance genes ride on imported seafood

A growing concern in the global health community is the rise of antibiotic-resistant bacteria, and recent studies indicate that imported seafood, particularly shrimp, might be a significant carrier. Researchers have discovered that shrimp often harbors colistin-resistance genes, which are alarming given that colistin is considered a last-resort antibiotic for treating severe infections. These findings suggest that the international seafood trade could be inadvertently facilitating the spread of these superbugs. The presence of colistin-resistance genes in shrimp underscores the challenges faced in controlling antibiotic resistance. As seafood is a staple in many diets worldwide, the risk of these genes entering the human food chain is significant. This situation is compounded by the fact that many countries have varying regulations concerning antibiotic use in aquaculture, making consistent enforcement of safety standards difficult. Consequently, consumers might unknowingly contribute to the spread of resistance by consuming contaminated seafood. Efforts to curb this growing threat include stricter regulations on antibiotic use in aquaculture and improved screening processes for imported seafood. Public health officials are urging governments to take coordinated action to monitor and manage the use of antibiotics in food production. Meanwhile, consumers are advised to stay informed about the sources of their seafood and consider supporting sustainable and transparent seafood practices. By taking these steps, it is hoped that the spread of colistin-resistance genes can be mitigated, preserving the efficacy of crucial antibiotics.
