Natural wax coating on Polish plums is safe, not pesticide residue

Fresh plums sold at Polish markets, such as the Łowicz market, often display a thin, matte white layer on their skin. This coating is a natural plant‑produced wax that protects the fruit from drying out, acts as a biological barrier against microbes, and signals that the plums were harvested by hand and brought to market shortly after picking.

The wax can be easily rubbed off with a fingertip, revealing a smooth, glossy surface. It should not be confused with mold, which appears fluffy or spotty and may require different handling. Consumers can safely eat plums with an even, mat‑like coating, as it indicates freshness rather than chemical contamination.

Guidance for shoppers includes checking that the white layer is uniform and smooth, and gently testing a small area; if the coating disappears without leaving residue, the fruit is healthy. Proper washing and handling are sufficient; no additional chemical treatment is needed.
