FBS & Global Biological Risk
You may be familiar with the terms “traceability” and “origin” in reference to fetal bovine serum (FBS), but how do these topics really impact the use of serum in cell culture? “Origin” is simply the country in which the raw material was collected. “Traceability” refers to the documentation roadmap that connects serum origin to final manufacturing and distribution.
So, why is origin important?
As viral patterns shift around the globe, the supply and quality
of bovine products such as FBS are affected. One of the most
recent issues to alter the global supply‐and‐ demand dynamic is
Bovine Spongiform Encephalopathy (BSE), more commonly known as
“mad cow disease.” BSE is a chronic, degenerative disease
affecting the central nervous system of cattle. The United States
Department of Agriculture (USDA) only permits the importation of
bovine products from those countries that are considered to be at
low risk for BSE. The spread of BSE, therefore, limits the global
supply of FBS, driving up demand for serum from the low‐risk
countries and linking FBS prices to perceived BSE risk; the lower
the BSE risk, the higher the cost of serum.
FBS & Global Biological Risk
Where is the risk?
Some countries, such as those within the European Union, are considered to present a very high risk of BSE and are not allowed to import bovine products into the United States. On the other end of the spectrum, are those countries that present no demonstrable risk at all. For example, New Zealand has never reported a single case of BSE. Due, in part, to its geographic isolation, New Zealand is perceived to be the safest current source for FBS.
As indicated on the map above, the Food and Agriculture Organization of the United Nations recognizes for risk categories for BSE:
- Risk Confirmed
- Likely Risk
- Unlikely Risk
- Highly Unlikely Risk
Gemini Bio‐Products sources all fetal bovine serum from the
lowest risk categories.
Our GemCellTM US Origin FBS comes exclusively from the United
States, while our other FBS products (such as BenchMarkTM and
FoundationTM) are sourced only from category 4 (lowest risk)
countries. Well‐documented traceability ensures the lowest risk.
Gemini collects raw serum only from countries that have been declared by the USDA to be free of specified bovine viruses, such as BSE. Each lot of our fetal bovine serum is fully documented and certified as to its country of origin. We work in close cooperation with the USDA to monitor FBS health and quality, employing an aggressive viral testing scheme to deliver only the safest and most well‐characterized products to our customers.
For more than twenty years, Gemini Bio‐Products has delivered culture with exceptional value.
