In the EU, calcium formate is used as a preservative in animal feed. It increases shelf life by acidifying the feed and inhibiting the growth of microbes. The addition of 15 g of calcium formate per kg of feed reduces the pH by one. The maximum feed concentration that the EU recommends is 15 g/kg; this level is believed to be safe for ruminants, chickens, fish, and pigs. At these dosages, the chemical has no negative environmental effects when used in feed. In growth media, calcium formate inhibits the growth of microorganisms such Enterococcus hirae, Pseudomonas aeruginosa, E. Coli, and Staphylococcus aureus. http://insightsmarketer.weebly.com/blog/unveiling-growth-prospects-calcium-formate-market-analysis
