Recomendaciones de conservación

Commercial storage guidance for all lettuce types: crisphead/iceberg, butterhead, cos/romaine and leaf. Storage life depends on initial quality, maturity, cultivar and handling; this is not a household shelf-life guarantee.

Lettuce is easily damaged by freezing and by ethylene, which causes russet spotting, so keep it just above freezing at very high humidity and away from ethylene-producing produce. Sensitive to ethylene: keep away from ethylene-producing fruit. Highest freezing point: -0.2°C. Source: USDA Agriculture Handbook 66 (rev. 2016).
