SLIDE 2
CBC, Jan 2014
“PESTICIDE RESIDUE FOUND ON NEARLY HALF OF ORGANIC PRODUCE”
SLIDE 3 “... consumers who often pay extra to buy
- rganic food might not always be getting
their money's worth?” "if the money is being spent to avoid pesticide residues and have access to food which is healthy, then I think the money is not well-spent ... [pesticides] will not be absent"
Do the CBC, and the experts they quote, really believe:
SLIDE 4
The CBC is correct in stating that
pesticides will not be absent. But the inferred premise – that pesticides (and GMOs) should have been absent – is flawed.
SLIDE 5 Syn pesticides and GMOs are prohibited...
- But does it follow that organic is being
misrepresented, or should be devalued, if trace levels of contamination are found?
- Does the CBC know what the organic
label means?
SLIDE 6
Objectives 1. To correct misinformation 2. To use the CBC’s trace contaminants story to explore the dependence of the mainstream agriculture on contaminants which are: * arguably unnecessary * intrusive and largely uncontainable * of unknown safety to human and environmental health
SLIDE 7 What does the organic label mean?
- Organic is a process guarantee –
NOT a product guarantee The organic label certifies how it was grown; that it complied with the rules as verified through a rigorous, annual, independent audit
SLIDE 8 What rules?
- Government of Canada. 2015. Organic
Production Systems. General Principles And Management Standards. CAN/CGSB-32.310-2015
- Government of Canada. 2015. Permitted
Substances Lists. CAN/CGSB-32.311-2015
- Organic standards started 2002 in US and
2009 in Canada
SLIDE 9
Why does organic NOT guarantee purity – freedom from contamination?
SLIDE 10
Canadian organic farms are islands in a sea of pesticides and GMOs
SLIDE 11 The threats of GM uncontainability
- Not limited to organic
- Not limited to liability (e.g. Schmeisers)
- Not limited to agronomic complications
- Enogen (GM corn for ethanol) has now
contaminated corn intended for milling * 1 in 10,000 kernels is enough to destroy utility for milling/processing * may have sickened people * StarLink revisited?
SLIDE 12
- Should Canadian regulators -
* just throw up their hands and say sorry, it is inevitable (and by inference, that it doesn’t matter anyway)? If containment of contaminants is literally impossible ....
SLIDE 13 If containment of contaminants is literally impossible ....
- Should Canadian regulators -
* just throw up their hands and say sorry, it is inevitable (and by inference, that it doesn’t matter anyway)? OR * rethink the premise that contaminant-based agriculture is, and should be, normalized?
SLIDE 14 What is a GM crop?
- a GM crop is just a conventionally bred
crop into which one or a few transgenes have been fitted
- Almost all GM crops contain just two
types of traits: herbicide resistance + Bt
- Almost all GM crops are for industrial use
– livestock feed, ethanol, plastics – corn, soy, cotton, and canola
SLIDE 15 What is a pesticide?
* biological (as neem) * mineral (as sulphur) * synthetic (as glyphosate)
- Pesticide = biocide = life killing
* herbicides * insecticides * fungicides etc.
SLIDE 16 Organic farmers don’t use pesticides??
Prohibited from synthetic pesticides
Substances List Examples from Permitted Substances List (GOC, 2015)
SLIDE 17 So is that the difference? Just the type of pesticide?
- No. It’s the context of use.
- Organic is designed for problem
avoidance, rather than problem solving
- Pest control is achieved by system design
- Pest outbreak means system dysfunction
- So – fix the system; not enough to just kill
the pest, as it will come back next year.
SLIDE 18
Pests are not born
They are created
SLIDE 19
NATURE BATS LAST Forcibly inserting ecologically dysfunctional practices into Nature ensures resistance: pest creation
SLIDE 20 Weed resistance to glyphosate
- Globally: 37 species; 269 biotypes
- Canada: 4 species, 8 biotypes
* tall waterhemp * burningbush * giant ragweed * horseweed
SLIDE 21 Pesticide use as viewed by the Canadian Organic Standard:
- Botanical pesticides shall be used in
conjunction with a biorational pest management program but shall not be the primary method of pest control in the farm plan. ....
SLIDE 22 Contrast this with conventional farming...
- ...where pesticide use has become
normalized; can’t imagine how organic farmers manage without them
- "before we go back to organic
agriculture, somebody is going to have to decide which 50 million Americans we are going to let starve or go hungry” (Earl Butz, US Secretary of Agriculture, 70s)
SLIDE 23 Pests are just assumed ....
- Reflected in up-front, prophylactic
use, even before planting, e.g. * insecticides synthesized in GM Bt crops assume insect pests * the herbicides enabled by GM herbicide resistant crops assume weeds * the neonic insecticide coatings on seed assume insect pests
SLIDE 24 Heavy pesticide use in California fruits/nuts/veggies
Alfalfa Rice Cotton Walnut Pistachio Almond Wine Grape Table and Raisin Grape Orange Processing Tomato Carrot Strawberry
5 10 15 Millions of kg per year (CDPR, 2016) 75% of 79 million kg used annually in California agriculture

50 100 150 200 250 300 350 kg a.i./ha (CDPR, 2016)
SLIDE 26 With organic, the goal is not to replace a synthetic magic bullet with an organic magic bullet, but to erase the premise of magic bullet solutions Instead of first, pesticides are last
SLIDE 27
Commercial scale organic??
SLIDE 28 By no means unique to organic Virtually nothing done on an organic farm is not done or could not be done
SLIDE 29
So why are we still using pesticides?
Who benefits?
SLIDE 30
TO INCREASE YIELD? TO REDUCE PESTICIDE USE?
Are GMOs beneficial to Canadians?
SLIDE 31 GM corn, soy (and canola) widely and rapidly adopted in Canada

Corn Soy Percent of harvested crop (Stats Canada, 2016)
SLIDE 32 Why? Now, few options due to the near absence of non-GM corn hybrid seed
GM traits (stacked HR and Bt) Non-GM (CSTA, 2015)

SLIDE 42
Based on 20 years in commerce .... GM has failed to live up to its promise to increase yield and reduce pesticide use
SLIDE 43
So why are we still growing GM crops?
Who benefits?
SLIDE 44 What would you call agriculture that has to be propped up by millions of kg
GM crops? And contaminates everyone else?
SLIDE 45 So, why are organic crops contaminated?
- 1 million ha of Canadian agricultural land
is now organic, but still <2% of the total
- Both pesticides and GMOs are pervasive
across the agri-food landscape
SLIDE 46 Jeff Carter, well known agricultural journalist, asks: is Canada’s
pesticide regulatory system broken?
right questions?
meaningful?
SLIDE 47 What can be done?
- So what options does an organic farmer
have to safeguard crops from contamination?
- Just how contaminated are organic crops?
SLIDE 48 How do organic farmers protect their crops from contamination?
- 100% organic farmer responsibility
- Failure of containment = decertification;
starting a 3 year process anew
- For pesticides: 8 m border with
neighbours; permanent hedgerows
- For GM: borders of 10 m (soy), 300 m
(corn), and 3 km (canola, alfalfa (seed), and apples).
(GOC, 2015)
SLIDE 49 Is GM (pollen) even remotely containable?
- kilometers for creeping bentgrass, sugar beet,
and canola,
- hundreds of meters for corn,
- tens of meters for wheat and cotton, and
- meters-to-tens of meters for rice, tobacco,
soybean, and barley Pollen (and seed) has always moved in field crop agriculture; but with GM, it is deleterious
(Clark, 2007)
SLIDE 50
How contaminated is organic produce?
SLIDE 51 Meta-analysis (11 studies) comparing pesticide residues on fresh fruits and vegetables # of Samples % positive pesticide residues Organic 66 10 Conventional 66 46
(Baranski et al. 2014)
SLIDE 52 Concentration of pesticide residues and DRI in lettuce (USDA PDP pilot study on lettuce)
No. Domestic Samples No. Different Residues Residues Detected per Sample DRI Organic 318 55* 0.17 0.075 Conven- tional 735 52 3.9 2.5 * 51 were permitted under organic rules
(Benbrook, 2011)
Conventional 120X higher
SLIDE 53 Do detected residues mean fraud?
(USDA Pesticide Data Program, 2002-2011, domestic-origin
- rganic produce; n=1168 residues)
- Legacy
- Post-harvest
- Permitted
- Other
- Persistent, e.g. DDT, dieldrin,
lindane, mirex
- Separate dedicated facilities
not required
Spinosad, and metabolites
following transition; mislabelling; or actual fraud
(Benbrook and Baker, 2014)
SLIDE 54 Origin of those pesticide residues:
- Legacy
- Post-harvest
- Permitted
- Other
- 18%
- 31%
- 22%
- 29%

SLIDE 56 Pesticide residues: It is not just number
- f, but how much and how harmful
SLIDE 57
SLIDE 58
SLIDE 59 What does trace contamination of organic produce mean to you ... ?
- A reason to question the value of organic
food? OR
- An unnecessary – but unavoidable -
infringement on your right to healthy, uncontaminated food?
SLIDE 60 Take home messages 1.
- rganic is a process guarantee, not a
product guarantee 2. fundamental design differences mean that the context of pesticide use differs between conventional and
SLIDE 61 Take home messages, con’t 3. commercial performance of organic farming today disputes the premise that exposure to pesticides and GMOs is a necessary risk 4. the issue is not the unavoidable, trace contamination of organic foods, but the wisdom of continuing dependence
- n contaminant-based agriculture
SLIDE 62
They can’t lead if we won’t follow
SLIDE 63 Trigger for action on non-compliant
- rganic pesticide residue levels
- Responsibility for detection and action is
vested in the Certifying Body (CB)
- If 5% or less than the MRL, CB informs
producer and follows-up at next scheduled visit
- If >5%, CB investigates immediately, provides
methods of corrective action to be completed within 90 days, and reports outcome
SLIDE 64 Golden rice... not so golden Forcible insertion of the transgene disrupted another gene, causing abnormal growth and low yield – not detected in earlier studies
