said Will Gannon, global product
manager at Hygiena. " But by
transitioning to a rapid method,
customers can release their
products up to four times faster,
reducing safety stock and
inventory investments, ultimately
providing them with significant
cost savings through a faster
time to results. "
Hygiena, Camarillo, Calif.,
produces rapid microbial detection,
monitoring and identification
solutions for the food and beverage
industry. The company's Innovate
System can provide results within
30 minutes and has the ability to
run 96 samples at once with no
secondary incubation needed. The
testing can be performed on a number
Rapid testing also allows for a faster response to adverse
events and make necessary corrections.
and FDA/BAM reference methods, the 3M Petrifilm plate
enables a single step detection via a gas bubble of the lactose
fermenting ability of this important class of organisms. With
this tool, it is possible to get an early warning of coliform
contamination within 14 hours of incubation with a confirmed
positive result in 24 hours.
COST SAVINGS
Rapid testing also allows for a faster response to adverse
events, allowing production facilities to implement corrective
actions that can prevent lost profits due to waste and spoilage.
" Traditional plating methods have additional, associated
hidden costs, whether it's the warehouse space required
to hold all of these products while they wait for the testing
results, or the safety stock and investments in inventory, "

of products including ultra-high temperature (UHT) milks and
creams, sauces, soups and beverages.
" Rapid ATP Bioluminescence truly streamlines the finished
product release process, ensuring the quality of the product,
while providing quicker time to results, typically by several
days, in most cases, " Gannon said. " This allows the processor
to rapidly identify any contamination in the products,
enabling them to improve the efficiency of the manufacturing
processes while also generating significant cost savings along
the way. Rapid methods give customers the information they
need to make an informed decision. "
Hygiena has worked with several dairy and dairyalternative
partners to test time to results for various
beverages, including UHT milk, extended-shelf life (ESL)
milk, oat milk and soy milk, to compare results obtained
with the Innovate System and those from traditional
culture methods or pH testing, with respect to the level of
detection and shortest time to results. In all cases, for all
microorganisms tested (except for Clostridium sporogenes
in ESL oat milk), the Innovate System was able to detect
low spike levels at a 24-hour time mark in contrast to other
methods which took at least 48 to 72 hours for results.
QUICK DETECTION
Conventional agar-based methods for the detection of E. coli
and coliform are also time consuming and labor-intensive
with confirmation steps for detecting gas production that can
take anywhere from 48 hours to several days, according to
Chandrapati. Coliforms are susceptible to most heat processing
conditions, including pasteurization of milk, therefore their
