Wholesale Lettuce Suppliers

Spain (Murcia, Almería) is Europe's largest lettuce exporter, supplying iceberg, romaine, and Little Gem to UK, German, French, and Scandinavian supermarkets from September to June. The Netherlands produces year-round butter lettuce (hydroponic and greenhouse) and speciality head lettuces for European premium retail. Germany exports hydroponic butterhead lettuce with roots (potted lettuce) across Europe. The United States (California — Salinas and Yuma) is the global benchmark for iceberg and romaine, with exports to Canada and limited volumes to Europe and Asia. Kenya exports premium baby leaf lettuces by air freight to European supermarkets, filling Northern European winter supply gaps.

Iceberg/crisphead (Batavia type): firm, crisp, long shelf life (21–28 days), dominant in UK and German retail and food-service. Romaine/Cos (tall, elongated head): standard for Caesar salad; dominant in US retail and growing in Europe. Butterhead/Bibb (Boston, Buttercrunch): soft, buttery leaves, short shelf life (7–10 days), dominant in French/Belgian retail, sold with root as "potted lettuce" in northern European markets. Loose-leaf/Lollo Rosso/Lollo Bionda: ruffled leaves, sold as whole heads or cut leaves in salad packs. Little Gem (mini romaine): UK and European premium retail growth category. Baby leaf lettuce blends: harvested at 14–21 days as cut shoots; the primary ingredient in mixed leaf salad bags.

Lettuce and leafy salads are the highest food safety risk category in fresh produce. EU Regulation 2073/2005 applies to all RTE fresh-cut leafy products: Listeria monocytogenes absent in 25g at end of shelf life; E. coli criteria apply at processing. FSMA Food Traceability Rule (Section 204, effective January 2026) mandates enhanced lot traceability for leafy greens including lettuce. The California Leafy Greens Marketing Agreement (LGMA) covers romaine and head lettuce in addition to spinach. Romaine in particular has been linked to multiple US E. coli O157:H7 outbreaks (2017, 2018, 2019) traced to the Yuma, AZ and Salinas, CA growing regions, leading to heightened FDA enforcement and industry-wide traceability requirements. FSSC 22000 and BRC/IFS for processing/fresh-cut pack-house facilities.
