Introduction
Formaldehyde is a colorless chemical compound that has a pungent smell used in many industries in the manufacture of products such as building materials, household equipment, and textiles. However, its use in the commercial food industry has been a major concern to the public since it is believed to have detrimental health impacts on human beings. However, formaldehyde is considered not to be an approved food ingredient, and yet it has been detected in foods in various ways; either as a natural constituent or as a result of food processing or contamination.
Why Is Formaldehyde Agent Banned in Many Countries?
You may have heard about the formaldehyde leaks happening commonly in food supply chains or several food products across the United States over the years. Though this may not only raise safety concerns and quality issues about different commercial food products that have been comprised of formaldehyde, it can indeed be concerning to even consume this chemical in moderate doses through contaminated or exposed food products.
Formaldehyde is a potent chemical that is usually harmless when it is found or even ingested or inhaled in small doses. However, when found in larger amounts in foods, this can lead to a toxic impact on one’s system.
Formaldehyde is a colorless gas that is known for its extremely strong smell commonly used for industrial purposes and well known for for its use in the construction or building materials. Food contamination with formaldehyde leaks or with larger amounts of formaldehyde is usually the gross result of industrial and environmental pollution. Whether it is the formaldehyde source that would be because of manufacturing or industrial processing facilities that use it or commonly from the manufacturing industry of wood products that use formaldehyde resins, these can be two potential sources of contamination from the industries.
Also from the exhaust from cars, trucks, or from cigarette smoke compounds, the chemicals in carpet or textile industries, or even the paint manufacturing companies, formaldehyde is a compound that has its fair share of usage in all these industries.
What Are the Commercial Purposes for Which Formaldehyde Is Used?
-
Most living beings, including humans, would be in fact according to current medical research producing formaldehyde by normal metabolic functioning itself. Well, this is because of the carbon cycle in most living organisms and humans, which is responsible for amino acid synthesis and DNA synthesis as well. As formaldehyde is one of the byproducts of the carbon cycle, in plants, living organisms, some animals, and humans as well, this byproduct of the carbon cycle can be a natural metabolic result. However, because of environmental pollution and industrial contaminants that have been indicated above as the sources of formaldehyde, ingesting the contaminated food sources can result in detrimental consequences to human health.
-
It would be important to note that the natural occurrence of formaldehyde in our body or even in other breathing living organisms and animals can be normal. It Is only when you are exposed to or ingesting high amounts of the potent chemical, when toxicity concerns or safety concern can be associated with.
-
Formaldehyde is known to be one of the indirect food additive forms according to information from the United States FDA (Food and Drug Administration).
-
This indicates that this chemical can be used in the processing of certain materials that can be into food contact. Presently, the Food and Drug Administration (FDA) has also classified its use among the defoaming agents, which is mainly when it is added to prevent the foaming of certain liquids or food products.
-
When formaldehyde gets dissolved essentially in water, it gets converted into the commonly used preservatives and disinfectant form of formalin.
-
In medical laboratories and medical colleges for the preservation and disinfection of cadavers, formalin can be used. In terms of the food industry, for both the cooking and smoking process, you would find formalin food preservatives at different concentrations in commercial markets.
-
Other commercial uses are held by the liquid formalin that has been approved by the FDA similarly for the decontamination of fish. In the fishing industry, this chemical is commonly used as an anti-parasite medication or treatment including the common salmon or catfish decontamination.
-
Further, even for fish eggs, formalin liquid is used as an antifungal agent for disinfection. For the prevention of spoilage and to extend the shelf life of commercially available fish in fisheries and fish markets, formaldehyde is a common treatment procedure. However, in some countries, owing to the safety concerns this chemical has now been completely banned while it is approved by the US FDA for commercial purposes enlisted above.
What Are the Permissible Levels of Formaldehyde?
According to the information given by The European Food Safety Authority (EFSA), though the levels of formaldehyde naturally occurring in food products or sources may vary widely and commercially, below are some of the common examples in food products where formaldehyde content can be regulated or deemed without safety concerns in these levels:
-
Fish: 0.005 to .2 ounces per pound.
-
Sugar: 0.00003 ounces per pound.
-
Produce: 0.0004 to 0.002 ounces per pound.
-
Meat and Poultry: 0.03 to 0.01 ounces per pound.
-
Milk: 0.022 to 0.03 ounces per pound.
-
Coffee: 0.002 to 0.001 ounces per pound.
From the above data, it can be said that side effects are not usually possible when ingested in trace amounts in food products (where it's used commonly as a disinfectant and food preservative).
According to the information given by the Agency for Toxic Substance and Disease Registry, in normal or trace amounts, there Is absolutely no risk at all with formaldehyde ingestion or consumption. However increasing amounts exceeding the levels indicated above (varying from medical bodybuilder regulations across different countries), can be a definite cause of food safety concern and in the case of young adults and children, often toxic and life-threatening in large doses.
Conclusion
Though your body cells can quickly break formaldehyde compound naturally without any cellular stress or significant impact, whether it is through ingestion or inhalation- it is to be noted that it is after all a natural byproduct of the carbon cycle in your body and cannot mean harm given that its rapidly absorbed as well as quickly metabolized by your gastrointestinal tract.
As of 2016 research reports in medical literature, the use of formalin in the food preservative industry is banned as per the information given by the European Union- deeming it carcinogenic potential. Further, it is important to ideally steer clear of foods containing formaldehyde because it is illegal in some countries to exceed even trace amounts in vegetables, fruits, milk, and meats.
