Approximately 70% of the fresh produce sold in the US contains pesticide residues even after they have been washed, according to a health advocacy advocacy group.
According to the annual analysis of the US Department of Agriculture's Environmental Working Group, strawberries spinach and kale are among the most pest-destroying products, while avocados, sweetcorn and pineapple have the least residue.
More than 92% of kale tested contained two or more pesticide residues, according to analysis One sample of conventionally grown kale could contain up to 1
Dacthal – the most abundant pesticide found in almost 60% of kale samples, is banned in Europe and is considered a potential human carcinogen in the US.
"We accept and support everyone should eat healthy fruits and vegetables as part of their diet, whether conventional or organic, says Alexis Temkin, a toxicologist working with the EEC.
"But what we're trying to highlight with the" Shopper's Guide to Produce "is Building In a series of evidence showing that mixtures of pesticides can have a negative impact.
Other foods on the "Dozen Dirty" list of the group include grapes, cherries, apples, tomatoes and potatoes. In contrast, the list of "clean 15" includes avocados, onions and cauliflower.
Leonardo Trasande, an environmental medicine specialist at New York University Medical School, called the EEC report "widely respected" and said he could inform shoppers who wish to buy some organic fruit and vegetables but would like to know which you could prioritize.
Despite growing research, scientists say it's difficult to know how many pesticides are exposed to people in their daily lives. It's also hard to say how these chemicals in combination affect the body.
A recent French study found that people who eat organic foods have a much lower risk of getting cancer underlying factors that would require more research. Harvard University nutrition experts warned that in this study, levels of residues in the participants' bodies were not analyzed to confirm exposure levels.
While 90% of Americans have detectable pesticide levels in urine and in the blood, the health consequences of consuming pesticide residues from conventionally grown foods are unknown, as are the effects of choosing organic foods or conventionally grown foods, of which known is that they contain less pesticide residues.
A separate Harvard study found that among women who undergo fertility treatment, those who took more pesticides, fruits and vegetables had a lower likelihood of live birth.
The CDC states that "a wide range of acute and chronic health effects associated with exposure to certain pesticides ", including effects on the nervous system, skin and eye irritation, cancer and endocrine disorders.
" The health risks of pesticide exposure depend on the toxicity of the pesticides on and the duration and route of exposure, "says the CDC, noting that children are at higher risk.
The Environmental Protection Agency sets rules for how pesticides are used, but these rules do not necessarily prevent cumulative exposure in the diet of a person.
The agency kä opposes a court order prohibiting Chlorpyrifos, a pesticide related to developmental disorders in children.
The EPA has also thought back which types of exposure it will take into account when assessing human health risks. President Trump has appointed a former industrial lobby group leader, American Chemistry Council, Nancy Beck, as head of its toxic chemicals unit.
