Formaldehyde— Animal feed preservative against Salmonella and E-coli detected in fish from Asia, a U.S study reported. One in four imported fish from China and Vietnam sold in the U.S supermarket contained a high level of Formaldehyde, according to tests conducted by a North Carolina chemical engineering firm and North Carolina State University.
Formaldehyde, popularly known in Asia as formalin (formalin is formaldehyde dissolved in methanol) is a toxic chemical compound (human carcinogen) commonly used as a medical disinfectant or embalming agent. Media reports say some Asian countries are using this dangerous chemical in fruits and other agricultural products to keep foods from rotting.
Reportedly, about 25 percent of all the fish products sold in supermarkets were found to contain potentially dangerous levels of formaldehyde. All of the fish found to contain the compound were imported from Asian countries. According to the study, not all of the Asian fish were contaminated, but many were.
Formaldehyde is, like many chemicals, surprisingly versatile. As a naturally occurring product it has its place in our bodies and in the environment and as a synthesized product its uses range from a key component in plastics and urea-based resins to being a vital component in treatments for animal feed to protect against Salmonella, E-coli and other harmful human bacteria and pathogens.
“The U.S. Food and Drug Administration have amended their regulations to provide for the use of formaldehyde (37% aqueous solution) at the rate of 2.5 kg. per ton of feed as an antimicrobial feed additive for maintaining complete poultry feeds salmonella negative for up to 14 days,” Feedstuffs publication stated.
