- Formalin is derived from formaldehyde which is a known cancer-causing agent. It is used to preserve bodies in mortuaries.
- It can also increase the shelf life of fresh food.
- 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?
- Fish is a highly perishable commodity.
- If it isn’t maintained at the proper temperature of 5 degrees Celsius, it gets spoilt.
- To avoid that and increase its shelf life, the sellers use chemicals such as formalin and ammonia.
- If the point of sale is far from the place of catch, formalin is used as a preservative.
- Meanwhile, ammonia is mixed with the water that is frozen to keep fish fresh.
