Sea Water
Untreated sea water can contain pathogens, microplastics, and contaminants and is not generally suitable for direct ingestion. When used as a food ingredient it must meet potable-water standards.
What it is
Water from the sea, containing dissolved salts (predominantly sodium chloride) and trace minerals.
Used in some artisanal foods (oyster brine, certain breads); more common in cosmetic preparations.
Why it's flagged
- high sodium
- potential microbial and chemical contaminants if not purified
What regulators actually say
"Bottled water shall... meet the standards of identity in this section and quality standards prescribed by 165.110(b)."
"Untreated water sources may contain microbiological and chemical contaminants."
