What Is Seafood Contamination
Seafood contamination occurs when harmful substances enter fish or shellfish. These can include bacteria, viruses, parasites, heavy metals, and industrial chemicals. Contamination may happen in water, during processing, or through improper storage and handling.
Common Sources and Health Risks
Major sources include polluted waterways, agricultural runoff, and inadequate sanitation. Pathogens like norovirus and Salmonella can cause foodborne illness. Heavy metals such as mercury may affect the nervous system, especially in vulnerable groups like pregnant women and young children.
Prevention and Safety Measures
Buy seafood from reputable suppliers and check for proper refrigeration and traceability. Cook seafood to safe internal temperatures and avoid cross-contamination in the kitchen. For guidance on standards and testing, refer to the FDA Seafood HACCP Manual.
