Microplastics in Seafood Singapore: A Startling Discovery
Microplastics in seafood have become a major concern in Singapore due to the potential health risks they pose to humans. Microplastics are small plastic particles that measure less than 5 millimetres in length and can be found in the oceans and seas worldwide. They are harmful to marine life, and when humans consume seafood that contains microplastics, it can lead to adverse health effects.
A study conducted in Singapore revealed that microplastics are present in commercially harvested seafood sold in supermarkets. The study found that microplastics were detected in three species of shrimp, ranging from 13.4 to 7050 items of shrimp. Additionally, microplastics were present in most types of seafood available in the Singapore market, including mussels, clams, and fish in various shapes and sizes, with polyethylene and polypropylene being the most abundant.
The prevalence of microplastics in Singapore's seafood has raised concerns about the health implications for Singaporeans. The consumption of microplastic-containing seafood is a route of exposure to humans and has implications for human health and food security. Therefore, mitigation strategies and public awareness campaigns are necessary to address this issue and ensure the safety of seafood products.
Key Takeaways
- Microplastics are present in commercially harvested seafood sold in Singapore's supermarkets.
- The consumption of microplastic-containing seafood poses potential health risks to humans.
- Mitigation strategies and public awareness campaigns are necessary to address the issue of microplastics in seafood and ensure the safety of seafood products.
Prevalence of Microplastics in Singapore's Seafood
If you're a seafood lover in Singapore, you may be concerned about the prevalence of microplastics in your favourite dishes. Microplastics are tiny plastic particles that can be harmful to both marine life and human health. Research has shown that microplastics are present in many types of seafood, including shrimp, mussels, and fish.
Sources of Microplastics
There are several sources of microplastics in Singapore's waters. One of the main sources is plastic waste that is not properly disposed of, which can end up in the ocean and break down into smaller particles over time. Another source is microbeads, which are tiny plastic particles that are used in some personal care products such as exfoliating scrubs and toothpaste.
Impact on Marine Life
The presence of microplastics in seafood is not only a concern for human health but also for marine life. When marine animals ingest microplastics, it can cause physical harm and even death. Microplastics can also accumulate in the tissues of marine animals, which can have long-term effects on their health and well-being.
Local Seafood Affected
Research has shown that microplastics are present in many types of seafood in Singapore. A study conducted in 2017 found that microplastics were present in all of the seafood samples that were tested, including fish, shrimp, and crab. Another study found that microplastics were present in commercially harvested shrimp sold in Singapore's supermarkets.
In conclusion, the prevalence of microplastics in Singapore's seafood is a cause for concern. While there are several sources of microplastics in the ocean, reducing plastic waste and properly disposing of plastic products can help to mitigate the problem. As a seafood lover, it's important to be aware of the potential risks associated with consuming seafood that may contain microplastics.
Health Implications for Singaporeans
Microplastics Ingestion
Given that Singapore is an island nation with a high seafood consumption rate, the presence of microplastics in commercially harvested seafood is a major concern. A study conducted on three species of shrimp from Singaporean supermarkets found that microplastics ranged from 13.4 to 7050 items of shrimp [1]. The ingestion of microplastics through seafood consumption is a potential route of exposure to humans and has implications on human health and food security.
Potential Health Risks
The potential health risks associated with the consumption of microplastic-contaminated seafood are not yet fully understood. However, evidence suggests that shellfish and other animals consumed whole pose particular concern for human exposure [2]. If there is toxicity, it is likely dependent on dose, polymer type, size, surface chemistry, and hydrophobicity [2]. Furthermore, microplastics can act as carriers of harmful chemicals and pathogens, which can accumulate in the food chain and pose a risk to human health [3].
It is important to note that further research is needed to fully understand the health implications of microplastics in seafood. However, the presence of microplastics in commercially harvested seafood highlights the need for increased monitoring and regulation of plastic pollution in marine environments.

Mitigation and Public Awareness
As the issue of microplastics in seafood becomes more widely known, governments and individuals alike are taking steps to mitigate the problem. Here are some of the initiatives being taken in Singapore:
Government Initiatives
The Singapore government has implemented several measures to reduce the amount of plastic waste in the country and raise awareness about the issue. For example, in 2019, the government announced a plan to phase out the use of plastic straws and replace them with more environmentally friendly alternatives. Additionally, the National Environment Agency (NEA) has launched campaigns to encourage Singaporeans to reduce their use of single-use plastics and recycle more.
In terms of seafood specifically, the NEA has also been working with the Agri-Food and Veterinary Authority (AVA) to monitor the levels of microplastics in fish and shellfish sold in Singapore. The AVA has also implemented regulations to ensure that seafood imported into Singapore meets certain safety standards.
Consumer Choices and Behaviour
While government initiatives are important, individuals can also make a difference by making more sustainable choices and changing their behaviour. One way to do this is by choosing seafood that is less likely to contain microplastics. For example, smaller fish tend to have lower levels of microplastics than larger fish, so choosing sardines or anchovies over tuna or swordfish can help reduce your exposure to microplastics.
Another way to reduce your impact is by avoiding single-use plastics when consuming seafood. This could mean bringing your own reusable containers to the fish market or choosing restaurants that use sustainable packaging.
Overall, there is still much to be done to address the issue of microplastics in seafood, but with government action and individual effort, progress is being made.
Frequently Asked Questions
What measures are being taken in Singapore to monitor and control microplastics in seafood?
The Singapore government is taking several measures to monitor and control microplastics in seafood. The National Environment Agency (NEA) has implemented a monitoring program to assess the levels of microplastics in seafood sold in local markets and supermarkets. Additionally, the Singapore Food Agency (SFA) is working with food importers to ensure that food products, including seafood, meet safety standards and regulations. The SFA also conducts regular inspections of food establishments to ensure that food safety standards are maintained.
Are certain types of seafood more susceptible to microplastic contamination than others?
Yes, certain types of seafood are more susceptible to microplastic contamination than others. A study conducted in Singapore found that shrimp sold in local supermarkets contained microplastics ranging from 13.4 to 7050 items of shrimp. Other studies have found that bivalves, such as mussels and oysters, are also highly susceptible to microplastic contamination. However, it is important to note that microplastics have been found in various types of seafood, including fish and crabs.
What steps can consumers take to minimise their intake of microplastics from seafood?
Consumers can take several steps to minimise their intake of microplastics from seafood. Firstly, it is recommended to purchase seafood from reputable sources that follow safety standards and regulations. Secondly, consumers can choose to consume seafood that is lower on the food chain, such as sardines and anchovies, as they are less likely to contain high levels of microplastics. Additionally, consumers can reduce their overall consumption of seafood and opt for plant-based protein sources instead. Finally, consumers can also choose to remove the digestive tracts of seafood before consuming them, as microplastics tend to accumulate in the digestive tracts of marine animals.
