We will be taking about fish. We
consume fish as part of our daily diet for its protein and vitamin. Fish
accounted for 26% of our daily protein diet. But are you aware that beside the fish
essential that we consume, we are also consuming other element together. One of
them that come in mind is formaldehyde. Formaldehyde is a chemical compound commonly
used for preservation of biological specimens. It kills most bacteria and fungi so to make
it suitable to use for preservation of specimens. Formaldehyde is
highly toxic to animal including human and it has been classify as a known
carcinogen, what this mean is clinical studies has shown that it can cause
cancer in human. A low dose will cause skin burn and irritation. Higher dose
will cause dizziness and abdominal pain. Long term exposure to formaldehyde
will cause nasal cancer.
Formaldehyde has made its way
into the fishing industry, where formaldehyde are being apply to fish product
to prolong its shelf live. Last year, 103 tons of fish from Malaysia and
Pakistan exported to Medan Indonesia were found to contain formaldehyde. The
shipment was quarantine off
and sent back to Malaysia. A layer of formaldehyde is spray on top of
the fish skin to prevent bacteria growth which is the leading cause of food
decay. Formaldehyde is colorless, so you wouldn't see it. Indirectly it reduces the operation cost by
depending less on refrigeration and less on special care during transportation.
Fish product reach the hand of consumer fresher but with the additional
preservative.
