As I rounded the corner, I saw it overflowing. The Sample
Outbox on my desk was practically bursting with several Ziploc baggies of
different colored powder. My heart did a tiny leap of joy as I thought to
myself, Look at all these samples I need
to send to the lab!
In a
previous post, I discussed how ingredient testing is a
large part of my job ["Raw Material Specialist (Extraordinaire)"]. I
also discussed how I consider samples that appear on my desk "presents",
because every new sample requires a preliminary Risk Assessment. But what is a
Risk Assessment, exactly, and why are they so fun?
Without realizing it, the average person does a risk
assessment almost every day.
At the grocery store:
If I park in the back, I'm less likely to get a door ding by a self-absorbed
teenager or a runaway grocery cart.
At work: If I don't
erase this last sentence in my email, I could be in big trouble.
At home: If it was
only on the ground for 5 seconds, it's still okay to eat.
For me, a Risk Assessment is an extensive background check
on a particular ingredient. The Risk Assessment considers the results of ingredient testing and a
literature search (among other factors).
Ingredient
testing is one way to make sure the ingredient is safe, but you have to know
what to test for.

You only get the results for the tests you request, so how
do you know what to ask for?
Sometimes the supplier will only test for Yeast and Mold and
Aerobic Plate Count (APC). APC is like a census – you may learn how many bugs you
have living there, but you can't tell how many of them are criminals. This is
why our standard ingredient testing regimen usually goes above and beyond the
tests an ingredient supplier will do on their own material. The literature
search also dictates what tests we request.
During my literature search, if I find any recalls for high
or unapproved pesticides, I need to make sure I request pesticide testing. If I
find reports of economically motivated adulteration (like putting vegetable oil
in something labeled 100% EVOO), I might test for identity or potential
adulterants.
Sometimes these searches turn up nothing significant…and
SOMETIMES, I hit the JACKPOT!
