Good feed hygiene is about protection and prevention. It’s not only imperative to animal health; it helps protect your workers, equipment, reputation, bottom line, and the entire food supply chain. Traditionally, many feed mill managers, quality managers, and nutritionists have relied on formaldehyde as a control against pathogens such as
E. coli, and other
Enterobacteriaceae. The use of formaldehyde is being challenged by authorities and the industry due to safety concerns.
Organic acids are widely recognized as the best available solution for safeguarding feed-food biosecurity. When used according to the label recommendations, they are safer for workers than formaldehyde and, when applied to feedstuffs, can help support overall animal performance and animal health by controlling pathogens in the feed. Yet single organic acids alone are not as efficient in pathogen control as formaldehyde.
Clever combinations are the key.
The good news is that the right combination of organic acids—such as formaldehyde-based solutions, antibiotics, and antimicrobials—can be a viable alternative to solutions that are under restriction or unauthorized in some regions. Working synergistically, short- and medium-chain fatty acids, together with other bioactive ingredients, can have an acidifying effect in a broad pH range and inhibit microbial activity. Using the correct combinations of acids and bioactive compounds can create a synergy where some components will work to increase the permeability of bacterial cells for other components to enter and disrupt normal cellular function.
