Can I eat fruits and vegetables that have been damaged by herbicides?

Question:

Answer:

Whether a crop is safe to eat after accidental exposure to a herbicide depends on several factors, including the type of herbicide used, its active ingredient(s), concentration, mode of action, and other relevant considerations. The safest course of action is not to consume any part of a plant that has been exposed to a known or unknown herbicide, and to remove and replace the affected plants.

2,4-D Damage on Dill — 2,4-D herbicide damage to dill. ⁽¹⁾

2,4-D Damage on Pepper — 2,4-D herbicide damage to pepper. ⁽²⁾

2,4-D Damage on Tomaoto — 2,4-D herbicide damage to tomato. ⁽³⁾

For perennial edible plants, like fruit trees, asparagus, and rhubarb, produce should not be consumed as long as the herbicide is present in the soil or the surrounding environment. Once the herbicide is gone from the environment, the time it takes for the crop to be safe for consumption varies depending on the product and growing conditions. It is typically at least one growing season. Check the product label or website for the pre-harvest interval and/or the time the product is persistent in the soil to know how long you must wait before harvest.

Even if you know the product used, the label typically will not provide safety information for fruits and vegetables, as they are not intended for use on these plants.

What Can I Do?

Depending on the time of year and the source of contamination, replanting the crop may be possible. However, some vegetable crops cannot be replaced and have sufficient time to mature and be harvested before the end of the growing season. There may be some alternative crops you can replant that require fewer days to reach maturity (such as green beans or radish).

Count the number of days from the anticipated replanting date to your average first frost date. Locate the days to maturity printed on the label or seed packet. As long as the days to maturity are fewer than the days left until frost, it’s worth attempting to replant. This article outlines the typical time frames from planting to harvesting needed for various vegetables: Vegetable Planting and Harvesting Times.

Additionally, many garden centers offer large, established vegetables in containers that can be purchased to replace damaged plants. If there is no time to replant, farmers' markets can be a good source of locally grown vegetables and fruits.
