CBC, Jan 2014

“PESTICIDE RESIDUE FOUND ON NEARLY HALF OF ORGANIC PRODUCE”

slide-3
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
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
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?

  • Do you?
slide-6
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
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
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
SLIDE 9

Why does organic NOT guarantee purity – freedom from contamination?

slide-10
SLIDE 10

Canadian organic farms are islands in a sea of pesticides and GMOs

slide-11
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
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
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
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
SLIDE 15

What is a pesticide?

  • Killing agent, includes

* biological (as neem) * mineral (as sulphur) * synthetic (as glyphosate)

  • Pesticide = biocide = life killing

* herbicides * insecticides * fungicides etc.

slide-16
SLIDE 16

Organic farmers don’t use pesticides??

  • WRONG!

Prohibited from synthetic pesticides

  • See Permitted

Substances List Examples from Permitted Substances List (GOC, 2015)

slide-17
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
SLIDE 18

Pests are not born

They are created

slide-19
SLIDE 19

NATURE BATS LAST Forcibly inserting ecologically dysfunctional practices into Nature ensures resistance: pest creation

slide-20
SLIDE 20

Weed resistance to glyphosate

  • Globally: 37 species; 269 biotypes
  • Canada: 4 species, 8 biotypes

* tall waterhemp * burningbush * giant ragweed * horseweed

slide-21
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
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
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

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

  • n organic farms
slide-27

Commercial scale organic??

slide-28
SLIDE 28

By no means unique to organic Virtually nothing done on an organic farm is not done or could not be done

  • n conventional farms
slide-29
SLIDE 29

So why are we still using pesticides?

Who benefits?

TO INCREASE YIELD? TO REDUCE PESTICIDE USE?

Are GMOs beneficial to Canadians?

Based on 20 years in commerce .... GM has failed to live up to its promise to increase yield and reduce pesticide use

slide-43
SLIDE 43

So why are we still growing GM crops?

Who benefits?

slide-44
SLIDE 44

What would you call agriculture that has to be propped up by millions of kg

  • f pesticides and

GM crops? And contaminates everyone else?

slide-45
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
SLIDE 46

Jeff Carter, well known agricultural journalist, asks: is Canada’s

pesticide regulatory system broken?

  • Are we asking the

right questions?

  • Are the answers

meaningful?

slide-47
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
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
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)

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

  • Azadirachtin (neem),

Spinosad, and metabolites

  • spray drift; carryover

following transition; mislabelling; or actual fraud

(Benbrook and Baker, 2014)

Origin of those pesticide residues:

  • Legacy
  • Post-harvest
  • Permitted
  • Other
  • 18%
  • 31%
  • 22%
  • 29%

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
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

  • rganic farming
slide-61
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
SLIDE 62

They can’t lead if we won’t follow

slide-63
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
