Wholesale Lettuce Suppliers for US Buyers

US fresh lettuce production is approximately 3.5 million tonnes per year. Salinas Valley, California (the "Salad Bowl of the World") is the dominant production region from March to November. Yuma, Arizona is the primary winter growing region (November–March). Mexico (Sonora and Baja California) supplements US supply during transition periods. The US bagged salad market — dominated by Dole, Fresh Express (Chiquita Brands), and Taylor Farms — drives massive demand for iceberg shred, romaine hearts, and baby leaf blends for both retail and foodservice supply chains.

Romaine/Cos: dominant in US foodservice (Caesar salad), growing in retail (hearts of romaine, 3-pack). Iceberg: largest volume by weight in retail and food-service; used for burger lettuce, taco shred, and coleslaw mix. Baby leaf blends (spring mix, arugula-spinach mix): premium retail growth category. Butterhead/Bibb: foodservice and premium retail; growing "living lettuce" (hydroponic with roots) format in premium US grocery. Arugula (rocket, Eruca sativa): distinct peppery flavour, often blended in spring mix; growing premium segment. Little Gem: emerging premium retail and restaurant salad category.

The California Leafy Greens Marketing Agreement (CA-LGMA) covers romaine, iceberg, leaf lettuce, and other head lettuces in addition to spinach. The Federal LGMA extends these standards nationally. FSMA Produce Safety Rule (21 CFR Part 112) applies to all lettuce farms. FSMA Preventive Controls (21 CFR Part 117) applies to fresh-cut processing. The Food Traceability Rule (FSMA Section 204), effective January 2026, requires enhanced lot-level traceability records for fresh-cut leafy greens including all lettuce types on the Food Traceability List.

Following the 2018 Yuma romaine E. coli O157:H7 outbreak (210+ illnesses, 5 deaths) and 2019 Salinas outbreak, FDA issued a Romaine Action Plan requiring: (1) grower-level water testing and agricultural water assessments; (2) label disclosure of harvest region on all romaine sold Oct–April from Yuma; and (3) enhanced end-to-end traceability. Buyers of US romaine should require LGMA membership, current Primus GFS or SQF audit, and lot-level harvest records for each delivery.

Q: What is the standard US retail pack for iceberg lettuce? A: Film-wrapped single head (1.5–2 lb / 680–900 g) or naked bulk heads in 24-count cartons (~40 lb / 18 kg). Pre-shredded iceberg (food-service/processing): 5 lb (2.3 kg) bags. Iceberg shred for burger chains: delivered in 10 lb bags or 50 lb bulk bags in modified atmosphere packaging.

Q: What is the California lettuce season schedule? A: Salinas Valley: April–November (peak June–October). Santa Maria, CA: year-round (mild coastal climate). Yuma, AZ: November–March (winter desert season). Transition periods (late March–April and late October–November) can see supply tightness and price spikes as production shifts between regions.

Q: What specification should I use for romaine hearts (hearts of romaine) for US retail? A: 3-pack of trimmed inner romaine hearts, each 8–10 inches (20–25 cm) long, 0.5–0.75 lb (225–340 g) per heart, vacuum-packed or MAP-packed in PE film. Shelf life: minimum 12 days from production date at ≤38°F. LGMA-certified origin. E. coli O157:H7 and Salmonella absent/25g; Listeria monocytogenes absent/25g.

Q: What is the FSMA Food Traceability Rule impact on my lettuce purchasing from January 2026? A: If you receive fresh-cut leafy greens including lettuce, you are a covered business under the Food Traceability Rule. You must maintain receiving records (KDEs) including lot codes, origin farm IDs, harvest dates, and quantity received. You must be able to provide this data to FDA within 24 hours of a request. Require your suppliers to provide compliant lot-level shipping KDEs with every delivery.

Q: Are there import options for premium butterhead or living lettuce for US natural grocery? A: Domestic hydroponic butterhead (living lettuce with roots) is produced by US controlled-environment agriculture (CEA) operators including Little Leaf Farms (MA), BrightFarms, and AeroFarms. These are the primary domestic supply sources. European imports of living lettuce are not commercially viable by ocean freight; the format is best sourced domestically. For air-freighted premium speciality varieties (e.g., Castelfranco radicchio, mizuna, specialty European heads), some specialty distributors import small volumes from Italy and France.
