food born vs foodborne

Foodborne (one word) is the correct adjective when you mean "carried or transmitted by food." The split form food born almost always reflects a typo or the wrong sense (as if food gave birth).

Quick answer

Use foodborne as one word (no space). Avoid "food born."

Correct: foodborne illness, foodborne pathogen, foodborne outbreak
Acceptable in some older or house styles: food-borne
Incorrect: food born (two words) or foodborn (missing e)

Core explanation: what "foodborne" means

The suffix -borne means "carried" or "transmitted" (compare airborne, waterborne). When combined with a noun it forms a single adjective: foodborne = carried by food. Writing food born separates the elements and either suggests an unintended meaning or looks like a mistake.

Right: The health department investigated a foodborne outbreak.
Wrong: The health department investigated a food born outbreak.

Grammar: borne vs. born and compound formation

Borne is the past participle used in transmission compounds; born refers to birth. Treat -borne like a suffix that fuses with the noun to make an adjective.

Use borne for "carried/transmitted by."
Use born only for birth: e.g., "She was born in 1990."

Hyphenation: is "food-borne" acceptable?

Most modern style guides prefer the closed form foodborne. The hyphenated food-borne appears in older texts or where a house style requires it. Use the hyphen only if your editor or publication mandates it.

Preferred today: foodborne
Acceptable if required by style: food-borne
Avoid: food born and foodborn

Spacing & typos: how "food born" slips in

Fast typing, autocorrect, or misremembering the compound causes errors. Also watch for the misspelling foodborn (missing the e), which spell-checkers may not always flag.

Search for: "food born", "food-borne", "foodborn".
Replace with: foodborne (or food-borne if your style requires it).
When in doubt, rephrase: "caused by contaminated food" or "an outbreak linked to [source]."

Memory trick & quick checks

Mnemonic: Think "airborne" → you wouldn't write "air born," so don't write "food born." Keep the fused form foodborne.

If you mean transmission: use foodborne.
If you mean birth: use born (e.g., "born in 1990").
