Farmed Shrimp Disease and Antibiotic Stewardship

Disease in shrimp aquaculture causes massive mortality and has driven problematic antibiotic use, with improving biosecurity and alternatives becoming increasingly important.

Key Facts

Early mortality syndrome caused by Vibrio parahaemolyticus has caused major losses in Asian shrimp farming since 2009
White spot syndrome virus can kill entire shrimp populations within 3-10 days of infection
Antibiotic use in shrimp farming — including banned substances — has led to trade rejections from importing countries
Probiotics, improved biosecurity and pathogen-specific management have reduced antibiotic dependency in leading operations
Specific pathogen free (SPF) broodstock programmes reduce disease introduction risk in farming operations
The scale of shrimp mortality events is enormous — millions to billions of individual animals dying in single outbreaks

Welfare Considerations

Disease in shrimp farming creates welfare concerns at extraordinary scale. Whether or not shrimp experience suffering in ways comparable to vertebrates remains uncertain, but the sheer number of individuals dying in disease outbreaks — and the conditions of intensive production that increase disease risk — warrant attention. The antibiotic use driven by disease management creates additional concerns for human health through resistance. Prevention-focused approaches that reduce disease incidence through biosecurity and SPF broodstock are preferable both for shrimp welfare and antibiotic stewardship.

What You Can Do

Choose shrimp products from certified farms with documented biosecurity and antibiotic stewardship
Advocate for stronger antibiotic use monitoring requirements in shrimp aquaculture regulations
Support innovation in shrimp disease prevention through probiotic and biosecurity research
Ask retailers about the antibiotic use practices of their shrimp suppliers
Consider reducing shrimp consumption given the combined welfare and environmental concerns
