What is formalin?

  1. Formalin is derived from formaldehyde which is a known cancer-causing agent. It is used to preserve bodies in mortuaries.
  2. It can also increase the shelf life of fresh food.
  3. While formalin can cause nausea, coughing, and burning sensation in the eyes, nose, and throat in the short term, it can cause cancer if consumed over a long period of time.

Why is fish laced with formalin?

  1. Fish is a highly perishable commodity.
  2. If it isn’t maintained at the proper temperature of 5 degrees Celsius, it gets spoilt.
  3. To avoid that and increase its shelf life, the sellers use chemicals such as formalin and ammonia.
  4. If the point of sale is far from the place of catch, formalin is used as a preservative.
  5. Meanwhile, ammonia is mixed with the water that is frozen to keep fish fresh.
