Microplastics have been detected in marine life across Malaysian waters, but health officials maintain that the risk to consumers remains low. The Fisheries Department confirmed that, while microplastics are prevalent in certain fish species, their presence in edible portions of seafood is limited, minimizing potential exposure for those who consume them.

Datuk Adnan Hussain, director-general of the Fisheries Department, cited national studies revealing that 93.3% of Indian mackerel examined contained microplastics in their gastrointestinal tracts. However, only 28.89% showed low concentrations of microplastics in the muscle tissue, which is typically consumed. He explained that since the digestive organs are usually removed during preparation, consumer exposure through standard fish fillets is generally negligible.

Noting exceptions for species eaten whole, such as small anchovies, cockles, or mussels, Adnan said these present a slightly higher potential for microplastic ingestion. However, he emphasized that overall dietary intake remains limited and does not warrant public concern over seafood safety.

Concerns about microplastic pollution have risen following findings in coral reef samples collected around Pulau Redang. Approximately 64% of 200 coral samples contained microplastics, with the highest concentrations detected near resort areas, diving centres, water sports zones, and vessel routes. These findings suggest that coastal and tourism-related activities contribute to microplastic contamination in sensitive marine ecosystems.

Adnan referenced international assessments, including those by the Food and Agriculture Organisation (FAO), which indicate that the health risk posed to humans by microplastics in seafood is currently considered low. He urged the public to continue consuming seafood, highlighting its nutritional benefits and importance as a protein source in Malaysia.

Since 2019, the Fisheries Department has been monitoring microplastic and macroplastic pollution along the northwestern and eastern coasts of Peninsular Malaysia and in Labuan, focusing on both commercial fish species and shellfish. Adnan stressed that monitoring alone is insufficient to address the issue, calling for measures to reduce plastic pollution at its source.

Proposed solutions include cutting down single-use plastics, enhancing waste collection and management on land and islands, promoting responsible disposal of fishing gear, and reinforcing producer responsibility for plastic waste. The department's approach aims to mitigate the environmental impact of plastic pollution while safeguarding public health through continued seafood consumption.
