Antibiotic residues in shrimp from aquaculture – 2025 study results indicate a need for action
The latest test results from the Chemical and Veterinary Testing Office Karlsruhe (CVUA) show: Antibiotic residues were detected in imported farmed shrimp in 2025 as well. The results underline the importance of regular checks along global supply chains.
Shrimp are among the most consumed seafood worldwide. A large proportion of the products imported into the European Union come from aquaculture farms in Asia and South America. However, intensive farming at high stocking densities favors disease outbreaks in the animals, which is why antibiotics are used both therapeutically and prophylactically.
Results of the residue analyses
In 2025, a total of 96 shrimp samples were tested for pharmacologically active substances.
The findings were as follows:
- In 6 samples, antibiotic residues were detected
- 3 samples did not meet legal requirements
- One sample was assessed as hazardous to health
The samples of concern showed, among other things, residues of tetracyclines, sulfonamides and a banned active substance from the nitrofuran group. In one case, a metabolite of a banned antibiotic was detected, which is considered potentially carcinogenic and genotoxic.
Additionally, one sample containing antibiotic residues above the permitted maximum level was labeled “antibiotic-free” – a clear violation of food law and a deception of consumers.
Why antibiotic residues are a problem for consumers
Antibiotic residues can have both direct and indirect effects on health. If legal maximum levels are exceeded or banned substances are detected, there is a potential risk from toxic effects or – depending on the substance – from carcinogenic and genotoxic properties.
Furthermore, even small amounts of antibiotics promote the development of antibiotic resistance. Bacteria can become insensitive to important medicines, making infections in humans harder to treat. Food can thus also contribute to the spread of resistant germs.
In addition, residues are an indication of problems in production, for example due to improper use of antibiotics or failure to observe withdrawal periods. This raises questions about quality assurance along the supply chain.
Implications for food safety
The results show that, despite existing regulations, residues of veterinary medicines can still occur in imported foods. Consistent monitoring is therefore essential to identify health risks early and to protect consumers.
BAV Institute supports companies with comprehensive analyses in the field of food safety. These include, in addition to microbiological testing, residue analyses to ensure compliance with legal requirements and to minimize risks along the supply chain.
