Microbial testing limits are unnecessarily stringent. In many cases, outdoor growers cannot sell
flower to retailers without undergoing irradiation, ozone treatment, or some other form of
remediation, even though the cannabis presents no public health hazard.
The presence of some microbes, such as E. coli and salmonella may indicate improper handling
or growing practices. Bile tolerant gram negative bacteria is often harmful if ingested. The
SGCA does not object to tests for these contaminants.
However, tests for yeast, mold, and total viable bacteria are over broad and underinclusive. In
many cases, these bacteria are naturally occurring and harmless. They may also be indicators of
good farming practices such inoculation with indigenous microorganisms or the use of living
soil. In fact, the Massachusetts Department of Agriculture allows for use of some pesticides
that include organisms which would cause cannabis to fail CCC required testing. For example, BT
NOW uses Bacillus thuringiensis ssp. kurstaki to control caterpillars.
The SGCA also recognizes that medical cannabis patients should have access to cannabis that is
nearly sterile. For this reason, we support recent regulatory changes that allow for different
microbial testing rules for medical cannabis versus adult-use cannabis.
For adult-use cannabis, microbial thresholds Microbial levels for adult-use cannabis produced
on outdoor farms should be increased and testing for “Total Viable Aerobic Bacteria (CFU/g)”
and “Total Yeast and Mold (CFU/g)” should be eliminated.
The high cost of unnecessary testing threatens to drive outdoor growers out of business. Under
the current CCC Guidance for soil testing, a Tier 11 outdoor grower is required to
spend $430,000 per year on soil and water testing. Not only are such costs untenable, but
these tests have no discernible purpose given that the regulations require testing of the final
products before they reach consumers.
CCC regulations require one sample per 100 square feet of beds. For 100,000 square feet, this
is equal to 1,000 samples. At New England Labs, for example, the full panel soil test is $430. At
Alpha Analytical, a full panel soil test costs $420.
Farmers are permitted to conduct composite sampling; regulations allow up to five samples to
be combined for testing, but there is a catch. Aggregate samples must meet a more stringent
threshold that is reduced proportionately, meaning that any composite sample must be below
20% of acceptable limits. Farmers who choose this route may save money, but they are taking a
big risk. Soil that meets state limits for contaminants can fail testing even if it would pass regular
testing, potentially costing them hundreds of thousands of dollars to remediate or replace soil
that is actually safe for growing. Failed results can also lead to the CCC requiring that operations
be ceased.
Water testing is required once a quarter so costs are not prohibitive. However, testing
standards require that water for outdoor cultivation meet drinking water standards. This
requires cultivators to use well water instead of rain or surface water unless it is aggressively
treated. This creates unnecessary costs for farmers, creates an unnecessary burden on the local
water table or municipal water source, and has no discernable purpose.
Why is it necessary to test water for contaminants when the final product is also tested?
Plants should not have to be tested for pesticide before transfer. A significant expense for
outdoor growers is how to store frozen cannabis, since it can be cost prohibitive to build and
run a walk-in freezer. At the same time, fresh-frozen may be the best way for outdoor farmers
to generate revenue. To address this issue, some transporters offer freezer trucks to transport
product.
Removing the pesticide testing requirement would allow outdoor farmers to harvest directly
into a freezer truck, effectively opening the fresh frozen wholesale market to outdoor farmers.
Alternatively, farmers could be required to take samples for pesticide testing and transfers could
be permitted while testing is underway. Fresh-frozen cannabis could be quarantined once it
arrives at its destination, and until test results confirm the cannabis is pesticide free.
Outdoor growers face a higher possibility of accidental pesticide contamination due to drift
from nearby farms.
Fines imposed for samples found with pesticide are excessive. SGCA is aware of one outdoor
farmer who is facing $125,000 in fines for positive pesticide test results, even though there is no
evidence that pesticide was used on the farm and no product ever reached consumers. Fines of
this size can put small farmers out of business.
Excessive fines advantage larger MSOs who can absorb such costs and also have their own
internal labs.
Outdoor growers often cultivate autoflowers to generate an early crop. These plants flower
early, and therefore remain small, often no more than a couple of feet tall or less. Putting
Metrc tags on these plants weighs them down and damages them because they are not big
enough to support the tag. Placing the tag in the ground does not work outside as it can be
blown away.
Autoflowers should not require METRC tags.
