No reason to panic
 these bugs are not known to cause any

Most Surprising Risk Assessment Discoveries
 Chagas disease is caused by the parasite Trypanosoma cruzi
 Recent outbreaks of Chagas in Brazil have been associated with acai juice
 Transmission of the parasite occurs through infected triatomine bugs,
mixed in with acai fruit as it is ground into pulp

No reason to panic
 just make sure the acai juice is
pasteurized

#4: Ginkgo Biloba
Itsnotwhatyou think!

Adulteration is high due to
consumer demand
1 g extract requires 50 g dried leaf
more demand than supply encourages adulteration

The Good News:
Adulteration forces the science community to
develop better testing methods, but consumers
should beware.

Ginkgo adulteration very widespread, say industry experts, so why is awareness low?
By Stephen DANIELLS, 05-Aug-2013
Adulteration of Ginkgo biloba is very widespread, according
to industry sources, but as the adulteration becomes more
sophisticated new methods are emerging to help industry
ensure the quality of this key herbal.

#5: Leafy Greens and
Grasses
GreenEyedGuide.com
For some ingredients, the literature
search doesnt turn up anything
odd, but the lab test results do!
3 examples
Most Surprising Risk Assessment Discoveries
#5: Leafy Greens & Grasses
GreenEyedGuide.com
(1) The Center for Science in
the Public Interest (CSPI)
rated leafy greens #1 among
the Top 10 Riskiest Foods
Regulated by the FDA
BUT  64% of the outbreaks
were due to Norovirus,
implicating poor food
handling (think Salad Bar)
(Not applicable for dry
powders)

#5: Leafy Greens & Grasses
GreenEyedGuide.com
(2) The Environmental Working Group puts spinach in the Dirty
Dozen and leafy greens in Dirty Dozen PLUS due to pesticide levels.
When we send powdered samples to the lab for testing, we DO
request pesticide testing, but I have not had any samples fail this test
(yet, knock on wood).

#5: Leafy Greens and Grasses
GreenEyedGuide.com
(3) After reviewing and testing MULTIPLE different samples of grass
powders (wheat grass, barley grass, oat grass etc) and leafy greens
(spinach and kale specifically), Ive come to learn and expect the
following:
 Leafy greens have inherently elevated lead & cadmium levels
 Grass powders have inherently elevated Aerobic Plate Count
levels (APC = like a census of bacteria, not an indication if those bacteria
are pathogenic or not)
*Not as big an issue with the food, whole as it is with the concentrated
dry powder
