may contain

Could include inside

May contain is a warning label indicating possible presence of an ingredient not deliberately added—typically allergens that might have contaminated a product during manufacturing: May contain traces of peanuts.

The phrase acknowledges uncertainty rather than confirming presence, covering the manufacturer legally while alerting sensitive consumers to potential risk.
