Food safety and a rapidly changing global market for animal feed and feed ingredients increase the need and urgency for development of sensitive, accurate, precise, fast, and economically feasible testing methods for multiple mycotoxins and Salmonella. Rapid methods are entering the market and being developed at an astounding rate, as evidenced by the amount of recent review information. Traditional methods are still widely used, but kits for rapid detection are gaining validation status by standardizing organizations. There are still many issues to resolve including very significant challenges related to representative sample collection to ensure no false negatives occur. Sampling plans will need to be globally harmonized for consistency but must be balanced with equity concerns for economic impact and food security in the sense of an adequate and safe food supply for developing countries. Sample processing and analysis still present limitations for detection of multiple mycotoxins, masked mycotoxins, and metabolically injured (viable but not culturable) Salmonella.
