Wholesale Spinach Suppliers for US Buyers

US fresh spinach production is approximately 350,000 tonnes per year, with California (Salinas, Santa Maria, Yuma) producing over 75% and Arizona supplying winter volumes. The bagged salad revolution (Dole, Fresh Express, Taylor Farms) made pre-washed baby spinach a grocery staple. US IQF spinach is sourced primarily from China, with some domestic frozen production in the Pacific Northwest. The fresh-cut processing sector (retail bags, foodservice bags) is the largest value segment of the US spinach market.

The California Leafy Greens Marketing Agreement (CA-LGMA) and Federal LGMA (Commodity Specific Food Safety Guidelines for the Production and Harvest of Lettuce and Leafy Greens) set the industry benchmark for spinach food safety. FSMA Produce Safety Rule (21 CFR Part 112) codifies many LGMA practices into federal law. FSMA Preventive Controls (21 CFR Part 117) applies to processing/fresh-cut facilities. Following the 2006 spinach outbreak, FDA traceback and traceability systems have been strengthened; the Food Traceability Rule (FSMA Section 204) requires enhanced traceability records for leafy greens including spinach from 2026 onwards.

Retail baby spinach: 5 oz (142 g), 6 oz (170 g), and 16 oz (454 g) MAP bags. Foodservice: 2 lb (907 g) and 4 lb (1.8 kg) bags. Clamshell packs (3 oz / 85 g): premium on-the-go retail. IQF chopped spinach (foodservice): 12 oz retail retail packages; food manufacturing: 10 kg poly bags. Spinach for juice/smoothie manufacturing: whole leaf, IQF or fresh, delivered in 20–25 lb bulk bags or bins. Triple-washed is the standard food safety claim on US retail packaging; some premium brands offer double-wash with no chlorine (differentiated natural channel claim).
