Animal Feed Contamination : Effects on livestock and food safety

The production of animal feed increasingly relies on the global acquisition of feed material, increasing the risk of chemical and microbiological contaminants being transferred into food-producing animals. This book provides an overview of research into animal feed contaminants and their negative effects on both animal and human health

Introduction to animal feed contamination; Animal feeds, feeding practices and opportunities for feed contamination: an introduction. Part 1 Contamination by microorganisms and animal by-products: The ecology and control of bacterial pathogens in animal feed; Detection and enumeration of microbiological hazards in animal feed; Assessment of the microbiological risks in feedingstuffs for food-producing animals; Detection and identification of animal by-products in animal feed for the control of transmissible spongiform encephalopathies. Part 2 Contamination by persistent organic pollutants and toxic metals: Hazardous chemicals as animal feed contaminants and methods for their detection; Animal feed contamination by dioxins, polychlorinated biphenyls (PCBs) and brominated flame retardants; Animal feed contamination by toxic metals; Aquaculture feed contamination by persistent organic pollutants, heavy metals, additives and drug residues. Part 3 Natural toxins in animal feed: Mycotoxin contamination of animal feed; Detection and determination of natural toxins (mycotoxins and plant toxins) in feed; Prevention and control of animal feed contamination by mycotoxins and reduction of their adverse effects in livestock; Dietary exposure of livestock and humans to hepatotoxic natural products. Part 4 Veterinary medicinal products in feeds: Feed additives and veterinary drugs as contaminants in animal feed the problem of cross contamination during feed production; Antimicrobials in animal feed: Benefits and limitations; Alternatives to antimicrobial growth promoters (AGPs) in animal feed; Chemical risk assessment of animal feed. Part 5 Risks from emerging technologies: Safety of genetically modified (GM) crop ingredients in animal feed; Detection of genetically modified (GM) crops for control of animal feed integrity; Potential contamination issues arising from the use of biofuel and food industry by-products in animal feed; Nanoscale feed ingredients and animal and human health. Part 6 Feed safety and quality management: Animal feed sampling for contaminant analysis; Ensuring the safe supply of animal-derived ingredients for animal feed; Management of animal feed safety in the USA; The GMP+ Feed Safety Assurance (FSA) scheme.
