What toxicological risk from lawn chemicals cannot be eliminated by thorough cooking of a garden snail?

Answer

Chemical residues absorbed into the snail's tissues

While extensive cooking, such as boiling multiple times, is generally relied upon to neutralize pathogenic threats like parasites, it is ineffective against certain chemical hazards. Snails found in managed suburban gardens have a high probability of absorbing environmental pollutants such as herbicides, fungicides, or insecticides into their actual tissues as they traverse treated areas. Because these chemical residues become incorporated into the snail’s flesh, standard cooking procedures, including boiling, do not break down or eliminate this inherent toxicological risk, similar to concerns regarding wild mushrooms grown in chemically contaminated soil.
