If you’ve noticed higher prices or empty shelves where the iceberg lettuce usually sits, you’re not alone. Shortages of iceberg lettuce have hit restaurants, grocery stores, and wholesalers hard over the last few years. If your business relies on fresh produce, staying informed about what’s behind these disruptions can help you plan and manage costs more effectively.
Below, we’ll break down the main reasons for the recurring shortage, walk through the timeline of key events, and offer practical insights on market trends and industry solutions.
Root Causes of the Iceberg Lettuce Shortage
There isn’t a single reason for the shortage. Instead, a combination of weather extremes, plant diseases, regional supply concentration, and labor challenges have created the perfect storm for iceberg lettuce.
Weather-Driven Setbacks
A key factor is the weather. California’s Salinas Valley—often called the “Salad Bowl of the World”—accounts for about 70% of all lettuce grown in the United States. Starting from late 2025 and into 2026, growers faced heavy rainstorms, unusually high humidity, and extreme temperature swings. Depending on the year, they wrestled either with too much rainfall, creating soggy fields and poor growth, or too little rainfall, leading to irrigation headaches and crop losses.
It’s not just California. Spain and other Mediterranean regions that supply Europe have struggled with destructive storms and intense rainfall. This has forced UK supermarkets to ration icebergs, sometimes with limits of three per customer. When the weather interferes, there’s little buffer to make up the loss quickly.
Rise in Plant Diseases: INSV and Pythium Wilt
A second area to consider is the spread of plant diseases, especially Impatiens Necrotic Spot Virus (INSV) and Pythium wilt, beginning in 2024. INSV is an insect-borne virus causing lettuce to become misshapen and discolored, while Pythium wilt—a soil-borne disease—leads to wilted, rotting plants.
Many farms reported outbreaks of both at the same time, particularly in the fall, and lost thousands of acres of product. These two diseases together have become the top biological threat to lettuce, and not just in one region. Once a field is infected, recovery is tough and often slow.
Heavy Reliance on Few Growing Regions
Salinas Valley’s dominance means that a local setback has national effects. When bad weather or disease cuts output there, it’s not easy for other regions to quickly pick up the slack. The same goes for Spain’s role in the European market. This “all the eggs in one basket” problem has made the supply chain more fragile than many realized.
Labor Shortages and Production Problems
Labor availability became another pain point, especially during and after the pandemic. California growers have signaled that skilled farm labor shortages—along with rising costs and inefficiencies—mean that even small hiccups can quickly snowball. For example, one large study showed that about 65% of iceberg lettuce is typically lost during production, well before it even reaches the store, mainly due to plant health and handling issues.
Timeline: Major Shortage Events
Understanding when and how these shortages unfolded can help you anticipate similar risks ahead.
Late 2022 to Early 2023: Double Trouble in North America
This was when the crisis first made headlines. In fall 2022, the Salinas Valley was hit by both INSV and Pythium wilt. The result? Wholesale carton prices for iceberg lettuce soared from about $20 to over $105. Dole, a major supplier, described it as a “complete crop failure” for part of the iceberg market. Heatwaves also wiped out up to 40% of local production.
During this period, overall U.S. lettuce output dropped nearly 12% from the prior year. Grocery prices for lettuce shot up nearly 18% year over year. Fast food outlets like Chick-fil-A and Subway posted notices to customers and sometimes swapped in alternative greens.
The market began to recover somewhat in January 2023, when production shifted to Yuma, Arizona, but distribution channels needed several weeks to refill. Pipeline shortages took time to clear out.
2023: Ongoing Gaps, Especially in Organic Supply
Organic lettuce growers in California saw cold weather and disease pressure continue to suppress supply. For at least a few weeks, some reported “very limited” organic iceberg and little to no product for the open market. Other varieties—romaine, red, and green leaf—were similarly affected.
2024 to Early 2025: New Rounds of Shortage
The cycle repeated during this period, with more combined effects from weather, disease, and labor gaps. Prices for a box of iceberg or romaine stretched up to $30–$40, about twice the typical amount. By the end of this stretch, prices softened somewhat, but actual supply volume stayed below average. Iceberg sales, for example, ran 12% under the previous five-year average.
Late 2025–Early 2026: Fresh Problems for Growers
By fall 2025, California growers sent warnings: due to rainstorms and high humidity, expect lower-than-normal product quality and tight supply. In early 2026, reports repeated a familiar story—low volumes and poor quality, as unstable weather made it hard to plant, grow, and harvest at full capacity.
Europe and UK: Supply Shocks from the Mediterranean
Many UK shoppers found shelves empty, as storms battered Spain and the Mediterranean during their harvest season. Supermarkets enforced purchasing limits, hoping to stretch supply between shipments. In Spain and Italy, heavy rains left fields too flooded to harvest, causing sudden and sharp drops in availability for several days at a time.
Current Market Trends and Quality
Iceberg lettuce is still under pressure. Current reports say supplies are “tight,” especially for pre-cut or value-added items like shredded lettuce or salad mixes. Markets expect ongoing shortages for several weeks anytime there’s a weather setback.
Producers and wholesalers describe lighter, less dense lettuce heads—sometimes with misshapen appearances or discoloration on the outer leaves. This is a direct result of weather stress and disease exposure.
Cool, damp weather in coastal areas like Salinas and Santa Maria has slowed harvests, reducing overall production by 10–15%. When large processors buy on the open market to meet contract obligations, this tightens supply even more—making fresh, high-quality iceberg harder to secure for restaurants and shops.
Impact on Prices and Supply Availability
The effects on prices and supply have been unmistakable. During the 2022 shortage, carton prices shot up from $20 to over $100. In more recent shortages, boxes sold for $30–$40, still double the usual rate. These swings make cost forecasting and menu planning difficult for any business buying in volume.
Restaurants often responded by changing menu items, warning customers about limited lettuce, or swapping in other greens. Some supermarkets, especially in the UK, rationed iceberg lettuce to ensure fair distribution—sometimes leading to “lettuce black markets” as frustrated buyers worked around the restrictions.
Even when prices come down, actual sales and shipped cartons remain lower than before. This shows that recovery in the supply chain can lag behind shifts in price tags.
Food Safety Issues Alongside Supply Shortages
While not as common as weather or disease problems, food safety scares can make a bad situation worse. For example, Taylor Farms once voluntarily recalled iceberg lettuce products linked to a cyclospora outbreak that sickened over 1,600 people in the U.S. This event further reduced available supply and strained sourcing alternatives.
If your business handles fresh produce, it is wise to keep documentation of sourcing and recall notices, and to update supplier contacts yearly.
How the Industry is Responding – And What’s Next
Breeding Better, Disease-Tolerant Lettuce
Industry scientists are actively testing lettuce varieties that can resist INSV and Pythium wilt. While progress is ongoing, partial resistance should help buffer future crops against devastating losses. For your purchasing plans, check if your suppliers participate in such research or trials, as this could mean a steadier supply chain down the line.
Building More Climate-Resilient and Diverse Supply Chains
Growers and distributors are working to expand production into additional regions—so a single storm or disease outbreak doesn’t have such an outsized effect. This might mean more contracts with growers in Arizona, Mexico, or even experimental farms in Canada. It’s a good practice to seek suppliers from more than one state or country, when possible, especially during high-risk seasons.
Shoring Up Labor and Supply Systems
Long-term, industry groups are focusing on better recruitment and retention for skilled farm work and improving production efficiency to bring more of each crop to market. That means automation, better plant care, and tighter waste management.
Depending on where you source lettuce or prepared salads, it’s smart to ask suppliers what steps they’re taking and how quickly they can respond to unexpected shortages or recalls.

Key Takeaways for Busy Entrepreneurs and Business Owners
Recurring iceberg lettuce shortages have created headaches for supply managers, restaurant owners, and grocers. Most shortages are driven by repeat patterns: extreme and unpredictable weather, aggressive plant diseases, and a heavy reliance on just a few production areas.
Plan for ongoing tightness, especially in late fall and winter when disease and storms are most likely. Engage with suppliers early, keep documentation of sourcing, and review delivery schedules each season. Be sure to check supplier updates in case of recalls or market alerts that could affect your regular purchases.
Stay on top of available research into disease resistance and watch for new regional suppliers who can fill gaps if California or Mediterranean sources are disrupted again.
By understanding the main drivers of shortages, staying alert for changes, and keeping lines of communication open with your suppliers, you’ll be in a stronger position to handle the ongoing challenges with iceberg lettuce supply.
