Seafood Handling and Temperature Control: Critical Success Factors

The Critical Nature of Seafood Temperature Management

Seafood represents one of the most temperature-sensitive food categories, with bacterial growth rates that can double every 20 minutes at improper temperatures. Australia’s extensive coastline and thriving seafood industry—worth over $3 billion annually—demands exceptional temperature management throughout the entire supply chain from ocean to plate.

Unlike other protein sources, seafood’s high moisture content, neutral pH, and natural bacterial load create ideal conditions for rapid spoilage. Temperature abuse of even 30 minutes can render high-quality seafood unsafe for consumption, making precise monitoring not just a quality issue, but a critical safety requirement.
