
Examine facts about organic foods
 Organic statistics
 What organic actually means
 National Organic Program
 Allowable vs. non-allowable substances
 How to tell if a product is organic
 Labeling requirements for organic foods
 To buy or not to buy – that is the question…
Objectives
Increase in sales from $11 billion to over
$30 billion in 2013
 Still account for only about 4% of all food
sales in the U.S.

Grown, produced and processed using
methods that:
 Encourage soil and water conservation
 Reduce pollution
 Improve the environment
What are organic foods?
Crops must be produced:
 Without synthetic, man-made pesticides
 Without synthetic, man-made chemical
fertilizers
 Without bioengineered genes
What are organic foods?
Organic meat, poultry, dairy and eggs must
be produced:
 Without added growth hormones
 Without antibiotics
What are organic foods?
Administered by USDA’s National Organic
Program
 Regulate how foods are grown, handled
and processed
 Organic certification requires verification
by third party audit

The standards
Farmers who sell less than $5,000 of
organic products per year
 do not have to be certified
 but to sell legally
 DO have to follow the NOP standards
 DO have to document that they do so
Exemptions
“Organic” means no chemicals can be used.
True or False?
Answer:
False
The common myth? No chemicals
can be used

NOP
 Reviews all synthetic substances for their use
in organic crop and livestock production
 Identifies even some naturally occurring
substances that are prohibited
 Publishes this information in the National List
of Allowable and Prohibited Substances in the
electronic Code of Federal Regulations
 Part 205
 http://www.ams.usda.gov/AMSv1.0/NOPPetitione
dSubstancesDatabase
National Organic Program

Chlorine compounds such as sodium
hypochlorite in bleach
 Allowable for use as a disinfectant
 In produce production, must rinse surfaces after
sanitizing to reach levels found in drinking water ~
4 parts per million.


Peracetic acid
Copper sulfate
Hydrogen peroxide
Ethanol
Isopropanol
Example of allowable substances
Important to remember:
• Even these can be toxic at some level
• Just because a chemical is “natural,” does
not mean it is non-toxic or 100% safe
Naturally occurring substances
Arsenic
 Lead salts
 Strychnine

Prohibited natural substances

Look at the label
 On single ingredient foods
 the word “organic”
 On fresh fruits or vegetables
 a small sticker version of the USDA organic seal
 OR a sign above the organic display
How can you tell if a product is
organic?

Look at the label
 On packages of meat, cartons of milk or eggs,
cheese or other single ingredient foods
 The word “organic” may appear
 The organic seal may appear
How can you tell if a product is
organic?
If the label says “100% organic”:
 It can only contain organic ingredients
If the label has the USDA seal:
 The product is certified organic
 95% or more of its ingredients are
organic
What about foods with more than
one ingredient?
If only 70% - 95% of the ingredients are
organic:
 The label can say “made with organic”
 The label can list up to three specific
organic ingredients
What about foods with more than
one ingredient?
For foods with less than 70% organic
ingredients
 These ingredients can only be listed in the
ingredient list
 No claim can be made elsewhere on the
label
What about foods with more than
one ingredient?

Fines of up to $10,000 per violation
What happens if retailers
knowingly sell a product labeled
“organic” that does not meet
these standards?


Many studies
Reviews show a lack of evidence that
organic is more nutritious than
conventional foods
 Nutrient content is affected by soil, growing
conditions, maturity at time of harvest, how
product is stored and handled
 Difficult to compare results
 Each study is a “snapshot” in time with
different conditions
More nutritious?
May reduce exposure to some synthetic,
man-made chemicals, but some are
allowed
 Some natural compounds can be toxic at
certain levels as well
 Any product used in conventional crop,
livestock or food production must be
reviewed and approved for safety prior to
use

Safer?

All milk, organic or conventional:
 Is tested for antibiotics to ensure standards are
met
 Grade A pasteurized milk ordinance requires
that milk contain NO detectable antibiotics
when analyzed using approved methods
What about antibiotics in milk?

If a cow becomes ill:
 Treated with the same antibiotics
 Organic cows will be removed from the organic
herd permanently
 Conventional cows will be removed from the
herd until the milk tests free of antibiotics
 Every truck load is tested
What about antibiotics in milk?
The milk is disposed of and not allowed to
go to market
 Farms can lose their permits to ship milk

What happens if antibiotic
residues are detected in milk?
Hormones are naturally present in:
 Organically produced milk
 Conventionally produced milk
Hormones have sometimes been used
conventionally to increase milk production.
 Use has diminished
 Consumer demands, not safety
Safety has been examined repeatedly over 15
to 20 years
 Has been reaffirmed to be safe
What about hormones in milk?
When milk is tested:
 There is no significant difference in
hormone levels in any milk.
 Our bodies do not have the receptors to
absorb bovine growth hormone.
What about hormones in milk?
Examine cartons of milk in stores
 Even many non-organic brands state that
their farmers pledge not to use growth
hormones.

READ THE LABEL!
“I can’t afford organic milk.”
All living animals have hormones in their
bodies
 All meat and poultry will contain
hormones
 Synthetic hormones are restricted for use
in organic livestock production and from
use in conventional poultry and pork
production
 Safety is evaluated prior to approval for
use and residues are monitored in beef

Are organic poultry and meat free
from hormones?
For consumers:
Buying organic is a personal choice
 Must decide if it fits their budget

Do I have to buy organic food to
have a safe and nutritious diet?
USDA Agriculture Marketing Service
 maintains a list at:
http://apps.ams.usda.gov/nop/
 Searchable by operation name, state and
crops or livestock grown
Is there a list of certified organic
operations?
