The U.S. centers for disease control and prevention
has estimated that approximately 48 million people become sick with foodborne
illnesses each year, that’s why more regulations and microbiological testing
have been enforced. In the past, Drs. Jim Gilchrist and Jeptha Campbell in 1976
have developed the spiral plating method and FDA established as an accurate
method to enumerate bacterial samples in food microbiology.
Advanced Instruments Inc. based in Norwood, MA, has
facilitated vast improvements in the field of spiral plating. The Autoplate is
the latest in microprocessor controller spiral plating technology and uses an
AOAC approved method to directly plated microbial suspensions with
concentrations ranging from 40 to 1,000,000 CFU/ml on 10 cm plates without the
need for serial dilution. This automated method’s unique features result in
greater sample repeatability and significant savings in time, labor and
disposable materials over conventional plating methods.
In the food industry, ongoing research continues to
determine the prevalence of pathogens, improve detection rates and develop
methods to raise the quality of the food supply in both raw and processed food
items and their ingredients. The autoplate is also ideal for those interested
in utilizing selective or differential agars since it can make up to 10
different plates using only one aspiration of sample.
Spiral plating has been an important tool for microbiologists in the food
safety field. The method provides accurate and precise enumeration, which then
heps identify pathogens that can be found in food. Using the autoplate
minimizes labor yet still meets the laboratory criteria of accuracy, efficiency
and sterility of samples. The time saved on sample preparation and plating can
help with the identification of new pathogens and improvements in food quality
control. The system will help with the speedy recognition of bacterial
outbreaks.
