Food and Beverage Testing
This section relates to food safety diagnostics involving bacterial contamination of raw materials, manufacturing equipment and manufactured product. The primary industries involved in this sector are catering and food service establishments, food and beverage manufacturers, meat processing and packing plants, dairies and breweries.
Foodborne transmission of pathogenic and toxigenic microorganisms has been a recognized hazard for decades. Food safety is evaluated in terms of acceptable levels of risk and is enhanced by systematically minimizing contamination at every point from food production and processing to distribution, preparation, and consumption. The food test menu includes a wide variety of organisms. The most common contaminants include: Salmonella, Shigella, Listeria monocytogenes, Escherichia coli O157:H7, Campylobacter jejuni, Vibrio parahaemolyticus, Yersinia enterocolitica, and others.
In the past 3-5 years food safety issues and concerns for public health have lead to more stringent legislation in food safety requirements. Legislation has produced increased demand for pathogen and toxin tests in just about every segment of the food production industry – processed food, meats, poultry, beverages, and dairy; and by all major food producers worldwide.
The market for food diagnostics is highly diversified and still developing. The food and beverage sector (food) is the largest segment within the industrial rapid test market. Overall, more than 600 million tests were performed, worldwide in 2005, with a market value of $1 billion. This sector is expected to see annual growth of 5% for the next five years.
In 2005/06 Lateral flow tests for food and beverage testing accounted for only 9% of all immunoassays used in this sector ($290 million, worldwide, in 2005). Improvements in performance and integration of new paradigms, such as nucleic acid lateral flow detection coupled with isothermal amplification methods will result in increased penetration of the market by rapid tests.
