Food Protection Trends - November/December 2017 - 515

Organisms used for inoculation: broth or plates? Influence
on heat resistance?
*	 In Sofia's personal experience, she found that organisms in broth exhibited better stability (more heat resistance) compared to organisms used from plate.
Sofia pointed out validation studies are performed in one
matrix should be verified in other matrices to understand if the
same inactivation kinetics apply.
Bob Buchanan pointed out that moisture migration and
re-distribution may be possible (based on his experience with
Pet foods risk assessment) when low moisture foods are
distributed through dynamic conditions (due to temperature
fluctuations) resulting in non-equilibrated conditions. So, future
studies should consider these variables. Bob also suggested
that characterization of strains (in preparation for inoculum)
must be performed.
Is there any work being done to work backwards from the
atypical incidents (that may lead to outbreaks and consumer
illness) to get an understanding of hierarchy of those incidents
so that we can prevent public health issues
*	 Some work has been done in pistachios and it is challenging because it is difficult to know the actual cause.
Requests are being made to investigators to enumerate the organisms when sampling occurs.
Which methods were used to enumerate Salmonella?
*	 Culture method using selective and non-selective
media. Selective media showed 1-log difference
because of cell damage.

(Brian Hawkins)
*	 Complicated risk assessment or classic hazard analysis - do we really need both/can we really do both?
(Yuhuan Chen and Bala Kottapalli)
*	 Biological variability (in thermal processing): Impacts
for process control and validation (Marcel Zwietering
and Heidy den Besten)
Webinars and Other Communications
*	 Marcel gave an overview of past webinars and
recordings, asked the group what would be an appropriate frequency for webinars. The recommendation
was two per year.
Recommendations to the Executive Board:
1. Recommend contacting firms like IBM who are working
with the food industry on BIG data across the industry
and finding a sway for them to summarize their findings
through webinars, symposia or informal sessions.
2. The MMRA PDG again had big support to recommend
that recordings of MMRA PDG webinars be made freely
available for both ALL IAFP Members and Non-Members.
It is especially the most generic subjects that would be
good to broadly diffuse.
3. Recommend finding a way to fund webinars through the
PDG for presentations that cannot be sponsored by a
commercial third party, due to the nature of the project
(such as a study by a government agency or WHO/FAO).
This would help make webinars freely available.
Next Meeting Date: July 8, 2018, Salt Lake City, UT.
Meeting Adjourned: 11:02 a.m. July 9, 2017.
Chairperson: Marcel Zwietering.
