Viruses and parasites can affect organic crops. Last year an organic frozen berry mix led to an outbreak of hepatitis A with 161 people falling ill. Pomegranate seeds were the cause of a similar outbreak in B.C. and organic bagged salads caused an outbreak of cyclospora parasite – infecting 631 people.
Although not necessarily a health problem, worm and insect infestations are more common in organic products since multiple synthetic pesticides cannot be used to control these organisms. The chances of eating worm or insect parts in jams or jellies is greater.
Many people believe organic foods are chemical free but this is not the case. Toxic chemicals occur naturally in the environment. Arsenic, cyanide, and formaldehyde all occur naturally in soil and water and can be found in organic food.
Earlier this year, CBC News Manitoba reported that: nearly half of the organic fresh fruits and vegetables tested across Canada in the past two years contained pesticide residue. While organic farmers are not allowed to use synthetic pesticides, they are allowed to use ‘natural’ pesticides such as rotenone, pyrethrum/pyrethrins, and neme. Although, natural pesticides are generally less toxic, they are still harmful. The range of possible contaminants is wider for non-organics but concentrations must fall below thresholds considered safe for human consumption in both organic and non-organic products.
There’s controversy about the use of Genetically Modified (GMO) crops such as corn and soy by some organic producers. Kashi was boycotted for a while because it was discovered that most of its soy came from GMO crops. The company worked to rectify this issue by joining the Non-GMO Project which verifies that the crops and other raw ingredients used for their products are GMO-free. But according to Kashi’s website, not all of their products are GMO-free yet. The Kashi case illustrates that some organic growers may not be excluding GMO crops, even the larger ones. While there is no actual science to back up the idea that GMO foods are dangerous; if you think you are buying natural food by buying organic, this may not be the case.
Bottom line: both organic and non-organic products may contain harmful bacteria, viruses, parasites, insects, chemicals, pesticide residue, and may include GMO. The most serious issue is that the risk of biological contamination is higher in organic food due to the use of manure and weaker cleaning agents. If you decide to purchase organic products make sure to choose your suppliers carefully, selecting only those that follow comprehensive food safety programs that ensure their products are safe.
