Is Organic Food Safer to Eat?

Check out this answer from Consensus:

While organic foods may offer some benefits, such as lower pesticide residues and reduced exposure to antibiotic-resistant bacteria, the overall nutritional differences between organic and conventional foods are minimal. The long-term health benefits of consuming organic foods remain uncertain, and more research is needed to draw definitive conclusions. Consumers should weigh the potential benefits and risks and consider their personal values and preferences when making food choices.

The debate over whether organic food is safer to eat compared to conventional food has been ongoing for years. With the increasing demand for organic products, it is essential to understand the potential health benefits and risks associated with their consumption. This article aims to provide a comprehensive overview of the safety of organic food based on current scientific research.

Nutritional Content and Health Benefits

Several studies have investigated the nutritional differences between organic and conventional foods. While some research suggests that organic foods may contain higher levels of certain nutrients, such as phenolic compounds and omega-3 fatty acids, the overall nutritional differences are often marginal and not clinically significant1 2 4 5. For instance, organic dairy products and meats have been found to have higher omega-3 fatty acid content, but these differences are unlikely to have a substantial impact on health2.

Pesticide Residues and Contaminants

One of the primary reasons consumers opt for organic food is to reduce exposure to pesticide residues. Studies have consistently shown that organic foods contain fewer pesticide residues compared to conventional foods1 2 5 6. For example, children consuming organic diets have been found to have significantly lower urinary pesticide levels1. However, the health implications of these lower pesticide levels are not entirely clear, as current exposure levels in conventional foods are generally considered safe6.

Microbial and Chemical Contaminants

The risk of contamination with microbial pathogens, such as Escherichia coli, does not differ significantly between organic and conventional produce1. However, the risk of isolating bacteria resistant to multiple antibiotics is higher in conventional chicken and pork compared to their organic counterparts1. This is likely due to the more intensive use of antibiotics in conventional animal farming, which is a significant concern for public health2.

Organic farming practices also aim to reduce the levels of environmental contaminants, such as heavy metals and persistent organic pollutants. While some studies have found lower levels of contaminants like cadmium in organic crops, other contaminants, such as certain pesticides and heavy metals, can still be present in organic produce due to environmental factors2 8.

Chronic Disease and Cancer Risk

The long-term health effects of consuming organic versus conventional foods are still not well understood. Some studies suggest that organic food consumption may reduce the risk of certain chronic diseases, such as obesity and allergic diseases, but the evidence is not conclusive2 4. A large prospective study in the UK found no significant reduction in the overall incidence of cancer among women who consumed organic food, although there was a potential reduction in the risk of non-Hodgkin lymphoma7.

Environmental and Ethical Considerations

Beyond personal health, many consumers choose organic food for its perceived environmental benefits. Organic farming practices are generally considered to be more environmentally friendly, as they promote soil and water conservation and reduce pollution from synthetic fertilizers and pesticides5 9 10. Additionally, organic farming often involves more humane treatment of animals, which can be an important ethical consideration for many consumers9.

Not at all. Witness the numerous cases of food poisoning from organic restaurants or from organic produce. Food safety practices are important regardless if the food is organically or conventionally grown.

Our organic monitoring reports have shown that organic foods are typically lower in pesticide residues, but conventional foods also typically comply with limits that are considered as being safe using risk assessments, e.g. from EFSA and other bodies. Therefore, the preference for organic foods typically has other reasons such as less pollution, higher ethics etc.

Food certified as “organic” is produced without the use of most synthetic pesticides and fertilizers, and without GMO-technology, ionizing radiation, or human biosolids (sewage sludge). It is difficult to say whether any of these prohibitions improve the health of consumers. Here’s what we do know:

1. Consumption of an organic diet significantly lowers exposure to several classes of synthetic pesticides. Numerous studies, in different populations and in multiple countries, have show that pesticide metabolite levels measured in human urine samples are immediately and significantly reduced when people switch from a conventional to an organic diet. However, available evidence is insufficient to determine whether these reductions are associated with improved health. Mother-child cohort studies in the US have shown that in utero exposures to pesticides at levels below regulatory safeguard limits are associated with subsequent behavioral and neurological effects in children, but it remains difficult to say whether pesticides exposures resulting from consumption of a conventional diet are sufficiently high to cause these effects.
2. A large prospective cohort study in France showed that people who eat organic diets are at significantly lower risk for cancer than those who eat conventional diets. However, this was an observational study and although the researchers controlled for many variables, there may be other differences beyond the decision to consume organic food that could be responsible for this difference in cancer incidence that the researchers were unable to adjust for.
3. While the health benefits of organic food consumption remain uncertain, we do know that synthetic pesticides pose a real health risk to the farm workers who help produce our food. In the US alone, an estimated 10,000 – 20,000 farm workers are acutely poisoned by synthetic pesticides each year, and organic food production clearly reduces the use of these synthetic pesticides and thus the opportunities for these adverse events.

Is eating organic is safer than eating conventional food? We cannot affirm that. There have been many food security concerns related to organic food, like the E. coli outbreak in France and Germany in 2011, due to the fact that organic farming uses manure, whose pathogenic microbiological content is more difficult to control than for synthetic fertilizers (King et al., 2012).

In fact, in proportion organic food retailers have more food safety notifications that conventional food retailers, for instance here.

Yes, in short, organic food is safe. What’s more, on average, organic food of plant origin is characterized by 12% increased content of polyphenols and vitamin C, a lower content of nitrates, and a trace presence of pesticides. Organic products of animal origin contain more beneficial for health unsaturated fatty acid. Organic dairy products, in contrast to meat products, are characterized by a higher content of protein and saturated fatty acids, however, the differences more result from the length of the grazing period and access to fresh forage than to the production system. Although generally, the consumption of organic food does not provide a significant nutritional advantage compared to a conventional diet, regular and frequent consumption of organic products generally reduces the risk of overweight and obesity, both for women and men, as well as non-Hodgkin lymphoma in case of women. Besides those, consumption of organic fruits and vegetables, as well as dairy products significantly reduces the risk of pre-eclampsia in pregnancy and eczema in infants, respectively. Positive effect on selected health problems probably results from a reduced amount of pesticide residues and an increased secondary plant metabolites intake which characterize organic food.
