What is the minimum suggested period land should be chemical-free before foraging snails found there?

Answer

At least one full growing season

Assessing the safety of a foraging location involves verifying the history of chemical use on that specific patch of land. If an individual cannot confirm with confidence that the area where snails are harvested has remained free from chemical treatments, such as herbicides or pesticides, for a specific duration, the risks are generally deemed too high. The recommended benchmark provided for establishing a sufficient period of environmental cleanliness is a minimum of one full growing season. Failing to meet this standard suggests the inherent risk of ingesting accumulated chemicals likely outweighs the culinary novelty of the meal.
