Microgreens vs Sprouts: The Difference and Food Safety
The two look similar in a store package, but they are grown and eaten differently.
- Sprouts are germinated seeds grown in water, usually in a jar. You eat the whole thing: seed, root, and shoot. Harvest is in a few days, before true leaves form.
- Microgreens grow in a tray of mix or on a grow mat under light. You cut the stems above the mix and leave the roots and seed hulls behind. Harvest is at about 7 to 28 days, when seed leaves are open.
The Microgreens Desk plans tray-grown microgreens.
Why Sprouts Carry More Risk
University of Minnesota Extension notes that sprouts carry a higher risk of foodborne illness because the whole seedling is eaten and harmful bacteria are often on the seed coat. Warm, wet jar conditions let them multiply. The FDA found that contaminated seed was the likely cause of most sprout outbreaks it reviewed from 2012 to 2020.
The FDA advises children, older adults, pregnant people, and anyone with a weakened immune system to avoid raw sprouts.
Microgreens are grown and harvested more like a leafy vegetable, which lowers the risk, but it is not zero. Treat them like any fresh greens.
Safe Habits for Microgreens
- Buy seed sold for sprouting or microgreens. Never use treated garden seed. Treated seed usually has a pink, blue, or green coating.
- Wash hands and trays before sowing. Scrub reused trays with hot soapy water.
- Use clean tap water and fresh mix for each tray.
- Cut with clean scissors above the mix. Do not pull roots and mix into the harvest.
- Rinse before eating and keep cut greens in the fridge.
- Throw out any tray with mold, a sour smell, or slimy stems.
