Contamination by fungi and bacteria: a preventable threat

Contamination by fungi and bacteria: a preventable threat

Contamination by fungi and bacteria of raw materials and feeds is a risk factor for animal health and a serious threat to the productivity of any farm. Therefore, eliminating their presence in feed and in the storage and distribution chain is a priority objective. To achieve it, applying a safe, effective antifungal and antibacterial treatment is essential.

Raw materials and feeds are exposed to contamination by fungi, bacteria and other biological agents during production, harvesting, transport, storage and distribution. Factors such as high temperatures, humidity, presence of oxygen, storage time, the physical state itself of feeds and use of contaminated machinery and facilities may promote the development of fungi and bacteria in all types of feed.

The presence of fungi and bacteria leads to a number of problems that may seriously affect animal health and compromise livestock farm productivity.

Problems resulting from contamination by fungi and bacteria

Health problems
• Mycotic diseases
• Diseases caused by mycotoxins
• Fermentation of feed and growth of bacteria
• Food-borne diseases and food poisoning (salmonella poisoning, etc.)

Nutritional problems
• Loss of nutrients
• Poor preservation of feed
• Worsening of flavour and aroma due to mold

Industrial problems
• Losses due to physical degradation of feed and formation of dust
• Risk of problems and accidents while handling feed at factories due to formation of dust.

A good antifungal treatment must ensure that feed retains its nutritional properties, as well as its aroma and flavour, and that it is free from substances that may affect animal health or yield. In addition, it must be effective for both decontaminating already contaminated feeds and ensuring long-lasting protection against other potential contaminations.
