Microbiological contaminants of animal feed.

摘要

The occurrence of pathogenic microorganisms in animal feed is risky for animals and, if transported by food of animal origin, may also pose a risk for humans. Moreover, permanent animal exposure to excessive saprophytic microorganisms in an unhygienic environment and feedingstuffs provokes pro-inflammatory cytokine production and an increase in metabolism activity, which, in turn, causes a decrease in productivity. Mycological contamination of animal feed may additionally cause mycosis, allergies and, above all, micotoxicoses. The most often detected microorganisms in animal feedingstuffs are Salmonella spp. and Clostridium spp. and factors of feed hygiene are aerobic bacteria count, fungi count, Enterobacteriaceae count and Clostridium perfringens count.
