The relationship between farmed fish and antibiotics is often debated, but the regulatory and scientific reality is very different from common perceptions. In the European Union, legislation strictly bans the use of antibiotics as growth promoters and prohibits indiscriminate preventive treatments. Medications can only be administered in the presence of a diagnosed disease and always under the responsibility of the farm’s veterinarian.
The use of antibiotics is targeted, usually through medicated feed, and always for a limited period. After each treatment, “withdrawal periods” must be observed, meaning the minimum interval before fish can be marketed, ensuring no residues are found in fillets destined for consumption.
Valentina Tepedino, a veterinary doctor specialized in food safety, emphasizes that this is not only a regulatory obligation but also an economic issue: “Antibiotics are expensive and complex to use. No serious producer has any interest in using them massively.”
Food safety is also safeguarded by competent health authorities, which conduct regular checks and residue analyses on seafood products. EFSA reports confirm that the presence of antibiotics in European farmed fish is extremely rare and, when detected, well below legal limits.
Aquaculture today
At the same time, aquaculture is increasingly reducing the use of pharmaceuticals thanks to innovation. The development of specific vaccines, genetic selection of more resistant species, improvements in farming practices, and more careful management of environmental conditions have led to a significant decline in antibiotic treatments over the past two decades.
The result is a production model that not only guarantees consumer safety but also strengthens sustainability and the competitiveness of companies. Talking about farmed fish “full of antibiotics” means ignoring scientific evidence and the real transformation of a sector that is ever more transparent and responsible.
The issue of farmed fish and antibiotics cannot be reduced to stereotypes. Strict regulations, rigorous controls, and technological innovation have made European aquaculture an advanced system, where the use of antibiotics is minimal and always under strict veterinary supervision.
