lautnusantara.com Radioactivity poses a serious threat to shrimp, both from a biological and food safety perspective. This hazard can occur to shrimp living in contaminated waters or even through exposure to radioactive substances during processing.

Here are some of the main hazards of radioactivity to shrimp:

1. Bioaccumulation and Biomagnification

  • Bioaccumulation: Shrimp, as part of the aquatic food chain, can absorb radioactive substances from water, sediment, and the food they consume. Substances such as Cesium-137 (137Cs) and Strontium-90 (90Sr) can accumulate in shrimp tissues over time.
  • Biomagnification: Radioactive substances that have accumulated in shrimp can then be transferred and accumulated to higher levels when the shrimp are eaten by other animals higher up the food chain, including humans. This process increases the health risk to consumers.

2. Biological Impacts on Shrimp

  • Genetic Damage: Exposure to ionizing radiation from radioactive substances can damage DNA and cause genetic mutations in shrimp. This can impact the survival, reproduction, and overall health of the shrimp population.
  • Health Harms: High doses of radiation can damage shrimp cells and organs, disrupt the nervous system, and even cause death. While low doses may not cause immediate death, long-term exposure can weaken shrimp and make them more susceptible to disease.
  • Reproductive Harms: Radioactive exposure can affect shrimp fertility, damage reproductive cells, and reduce the number of offspring produced. This can significantly impact the sustainability of shrimp farming.

3. Hazards to Human Consumers

  • Cancer Risk: When humans consume radioactively contaminated shrimp, the radioactive substances can enter the body. For example,137Cs tends to accumulate in muscle tissue, emitting radiation that can damage body cells and increase the risk of chronic diseases, including cancer, especially blood cancer (leukemia).
  • Acute Radiation Sickness: Although rare through food consumption, exposure to very high doses of radioactive material from heavily contaminated shrimp can cause symptoms of acute radiation syndrome, such as nausea, vomiting, and nervous and digestive system disorders.

4. Economic and Trade Impacts

  • Product Recalls: The discovery of radioactive contamination in shrimp, such as the recall of frozen shrimp products from Indonesia in the US market, can trigger mass product recalls. This not only harms producers financially but also damages the reputation of a country's fishing industry.
  • Export Bans: Importing countries can impose export bans on fishery products suspected or proven to be contaminated. This causes significant economic losses for the fishing sector and fishermen.
  • Reputational Loss: Issues of radioactive contamination raise concerns and distrust among consumers. Even if the radiation levels are low, these concerns can lead to a significant reduction in market demand.

To address this danger, strict monitoring, investigation of contamination sources (e.g., industrial waste, hospital waste, or nuclear testing), and the implementation of strict safety standards are crucial.
