The discovery of radioactive material in shipping containers carrying shrimp from Indonesia has sparked international alarm, leading to product recalls in the United States and heightened scrutiny over seafood imports.
Important details
- U.S. Customs and Border Protection (CBP) detected unusual levels of cesium-137 in multiple shrimp shipments.
- The contamination has been traced to PT. Bahari Makmur Sejati, an Indonesian seafood company.
- Indonesian authorities say the issue stemmed from an external accident beyond the company’s control, though details remain undisclosed.
- Some contaminated shipments entered U.S. commerce, prompting recalls.
- The FDA has placed PT. Bahari Makmur Sejati on Import Alert 99-51 for chemical contamination.
- Experts warn that repeated low-level exposure to cesium-137 could increase long-term cancer risks.
Official findings
CBP inspectors discovered the contamination during routine screening at several major U.S. ports, using radiation detection and non-intrusive inspection technologies. Subsequent analysis by CBP’s Laboratories and Scientific Services confirmed the presence of cesium-137 (Cs-137), a radioactive isotope produced in nuclear reactions and widely used in medical and industrial applications.
The FDA determined that shrimp from PT. Bahari Makmur Sejati had been prepared, packed, or held under insanitary conditions. The agency concluded that the products were adulterated under the Federal Food, Drug, and Cosmetic Act. To safeguard consumers, the company has been placed on Import Alert 99-51, blocking its shrimp products from entering U.S. commerce until corrective actions are verified.
Affected ports
The following table outlines the U.S. ports where contaminated shipments were detected:
U.S. Port | Contamination detected | Shipment status | Potential health risks (cesium-137) | Groups most at risk |
Los Angeles | Yes | Detained | Long-term exposure linked to increased cancer risk | Children, pregnant women, elderly |
Long Beach | Yes | Detained | Same as above | Same as above |
Houston | Yes | Detained | Same as above | Same as above |
Savannah | Yes | Detained | Same as above | Same as above |
Norfolk | Yes | Detained | Same as above | Same as above |
Elizabeth, NJ | Yes | Detained | Same as above | Same as above |
Miami | Yes | Detained | Same as above | Same as above |
Exact shipment numbers have not been disclosed by CBP.
Affected brand
The recalls and trade restrictions specifically involve shrimp products from PT. Bahari Makmur Sejati, an Indonesian seafood exporter. According to Indonesian officials, the radioactive exposure was the result of an accident outside of the company’s facilities. However, until the source of contamination is fully addressed, all shipments from this supplier remain subject to import restrictions and heightened inspection.
The recalls have impacted several brands and distributors operating in the U.S. market, including:
While federal agencies continue to investigate the source of contamination, seafood buyers and distributors are being urged to review their supply chains closely and verify the origin of imports before reaching consumers.
Cause of contamination
Indonesian officials believe the radioactive exposure was caused by an accident unrelated to the company’s direct operations. Details of the incident have not been publicly disclosed and remain under investigation.
The FDA reports that while cesium-137 levels detected in the shrimp are not expected to cause immediate harm, prolonged or repeated consumption of contaminated seafood could elevate cancer risks over time. Vulnerable populations, such as children, pregnant women, the elderly, and immunocompromised individuals, face the highest levels of concern.
Global implications
This case highlights the growing challenges of maintaining food safety in global trade. Beyond traditional risks like bacterial contamination or mislabeling, chemical and radiological hazards are now entering the spotlight.
Key implications include:
- Enhanced inspections – U.S. authorities may increase the frequency and scope of radiation monitoring across ports.
- Trade impact – Indonesian seafood exports could face broader restrictions, potentially affecting global shrimp supply.
- Consumer trust – Recalls tied to radioactive contamination could heighten consumer caution toward imported seafood.
What consumers should know
The FDA advises consumers to avoid shrimp products linked to PT. Bahari Makmur Sejati until further notice. While acute health risks from cesium-137 are considered low at detected levels, long-term exposure remains a concern. Consumers are encouraged to monitor recall notices, dispose of affected products securely, and seek medical guidance if they suspect exposure.
Moving forward
The incident remains under investigation in Indonesia, with international regulators watching closely. Both U.S. and Indonesian authorities reaffirm the importance of strong safety protocols to protect public health and preserve confidence in the global seafood supply chain.
