A new French study has confirmed that residents living near vineyards are more heavily exposed to pesticide residues than those farther away, with higher levels recorded during spraying periods.
The findings, released September 15 by the French health and safety agencies ANSES and Santé publique France, come from the largest national survey to date on pesticide exposure in wine-producing regions.
The study, known as PestiRiv, analyzed exposure levels among 2,000 adults and 750 children across 265 sites in six vineyard regions of mainland France. Researchers found that individuals living within 500 meters of vines showed significantly higher traces of pesticides, with children aged 3 to 6 years most affected during active spraying seasons. While the study did not evaluate health outcomes, it provides the first large-scale evidence of what the agencies called “surimpregnation,” or overexposure, of populations near vineyards.
Study Details and Key Findings
PestiRiv is the first biomonitoring program in France to focus specifically on vineyard regions. Sampling was carried out both during and outside of pesticide application periods to identify seasonal variations in exposure. Biological samples from participants, including urine tests, revealed higher levels of certain pesticide biomarkers during the spraying season, particularly among children.
According to Santé publique France, the goal was to establish an objective measure of exposure rather than to assess immediate health risks. “The objective of this study was not to evaluate the health effects of pesticides but to measure the impregnation of residents,” said Santé publique France in its statement. The results indicated a clear correlation between proximity to vineyards and pesticide absorption in the body, with levels rising sharply in areas where spraying was active.
Children emerged as the most vulnerable group. Those aged 3 to 6 years living near vineyards showed the highest biomarker concentrations. Researchers attributed this to physiological differences and the fact that children spend more time outdoors during the day. The findings underline concerns about the potential long-term impacts on local populations, even if the study itself did not address specific health conditions.

France is the world’s most visited country and one of the leading destinations for wine tourism, with regions such as Bordeaux, Champagne, Burgundy, Alsace, and the Loire Valley drawing millions of visitors annually. While the study emphasized local residents, the results have implications for the growing wine tourism industry, which has been expanding in both volume and global reach.
The research does not suggest significant health risks for tourists visiting vineyards on short stays. However, it adds to the wider debate on sustainability in viticulture and how vineyards present themselves to international visitors. For many wineries, environmental practices are increasingly central to their tourism offerings, with organic and biodynamic methods highlighted during tastings and tours.
Industry observers note that the demand for eco-certified vineyard experiences is rising. Labels such as “Haute Valeur Environnementale” (HVE) and EU organic certifications are now commonly promoted as part of wine tourism marketing. These certifications indicate reduced or eliminated use of synthetic pesticides, aligning with consumer expectations for responsible and sustainable travel options.
Environmental and Policy Implications
The findings arrive amid ongoing debates in France and the European Union about pesticide regulation and rural protections. Buffer zones between vineyards and residential areas have been a contested issue, with local residents often demanding stricter measures to limit exposure. The confirmation of higher contamination rates in populations living close to vines is expected to add weight to calls for tighter regulation.
For the tourism sector, the study highlights the importance of how vineyard regions manage both environmental health and public perception. Sustainability is increasingly a competitive factor in attracting international travelers. Wine regions that adopt pesticide-free or reduced-pesticide practices may gain an advantage in appealing to environmentally conscious visitors, particularly from markets such as Northern Europe and North America.
Although the study did not assess direct health risks for visitors, it may encourage travelers to favor tours and accommodations that emphasize organic practices. This trend is consistent with broader shifts in global tourism, where environmental stewardship is becoming as important as cultural and culinary experiences.
The PestiRiv study represents a milestone in measuring pesticide exposure in French vineyard regions. Its conclusions are likely to influence future policy decisions on pesticide use and local protections for communities near agricultural areas. For the wine tourism industry, the findings create both challenges and opportunities: a challenge in addressing growing environmental concerns, and an opportunity to lead in sustainable practices that attract a new generation of travelers.
Bottom Line: The study confirms that residents near French vineyards are more exposed to pesticides, particularly during spraying periods, with children most affected. While the findings do not point to immediate risks for wine tourists, they reinforce the importance of sustainable viticulture and may shape how vineyard regions market themselves to international visitors.
