Room Temperature Safety
40°F–140°F (4°C–60°C)
Perishable foods, including fresh mizuna mustard greens, should not be left at room temperature for more than 2 hours (or 1 hour if the temperature is above 90°F/32°C). Bacteria multiply rapidly in the danger zone, increasing the risk of foodborne illness.
Safe Handling
Wash mizuna mustard greens thoroughly under running water before eating or preparing to remove dirt and potential contaminants.
Avoid cross-contamination by keeping fresh greens separate from raw meats, poultry, and seafood.
Discard any greens that appear slimy, discolored, or have an off odor.
Do not wash greens until just before use to prevent premature spoilage.
