About

What it is and where it shows up.

Edible seeds of the watermelon plant (Citrullus lanatus), consumed roasted or raw as a snack and used in food preparation across sub-Saharan Africa and Asia; valued for their protein, healthy fat (including linoleic acid), magnesium, zinc, and amino acid (arginine and citrulline) content. They are a traditional whole-food ingredient, not a chemically isolated food additive.

Safety summary

The regulatory and scientific consensus.

Watermelon seeds are broadly considered safe as a traditional whole food with a long history of consumption in Africa and Asia; no specific ADI has been established by any major regulatory body. A 21-day rat study found body weight decreases in males and reproductive organ weight changes at 2.5–5% dietary supplementation, warranting caution at very high chronic intake levels. No IARC carcinogenicity classification exists for watermelon seeds.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
EFSA (European Food Safety Authority) (European Union)	Approved	Watermelon seeds are not classified as a novel food in the EU and are permitted as a traditional whole-food ingredient with no E-number or food additive authorisation required. EFSA has not issued a dedicated safety opinion on watermelon seeds specifically.source
FSSAI (Food Safety and Standards Authority of India) (India)	Approved	Watermelon seeds are formally recognised under the Food Safety and Standards Regulations (FSSR); FSSAI has also established fatty acid composition standards for watermelon seed oil within its edible oils regulatory framework, confirming legal food ingredient status.source
FDA (Food and Drug Administration) (United States)	Approved	Watermelon seeds are regulated as a whole-food agricultural commodity, not as a food additive. No specific GRAS notice or food additive petition is on record; permitted under common-use provisions of 21 CFR. No regulatory restrictions identified.source

Who should approach with care

Whose guidance would steer them away.

Kidney Disease — Watermelon seeds are high in protein, magnesium, and phosphorus; individuals with impaired renal function may struggle to excrete these nutrients adequately, and the PubMed rat toxicity study (PMID:33682546) specifically monitored kidney biomarkers (urea, creatinine) as endpoints of concern at high dietary doses.

Gout — As a protein- and purine-containing seed, high consumption of watermelon seeds may contribute to elevated uric acid levels; clinical guidance broadly recommends that people with gout moderate intake of purine-rich foods.

Infants — Whole watermelon seeds present a choking hazard for infants and young children, and their high fat and protein density is unsuitable for very young digestive systems.
