Reducing Fish Waste by Cutting Down on Antibiotic Residues

The middle part of a food chain—small and medium businesses that move products from farmers to stores—is often overlooked, yet it can hide safety problems and cause significant food waste.

Key Findings

• Scope of the study: 247 regions in China, 2015‑2022.
• Focus: Antibiotics that persist in fish and other aquatic foods.
• Impact of exceeding legal limits:
• 44,200 tons of fish lost in six provinces.
• Health risks higher than the safety threshold.

Innovative Solution

Researchers developed a mathematical model to pinpoint where food testing would be most effective. The results:

Takeaway

By directing regulatory attention to how antibiotics spread through the hidden middle of supply chains, China can:

• Enhance food safety
• Protect public health
• Boost food security
