Grimmway Farms: E. coli O121 Outbreak and Multi-Brand Organic Carrot Recall

In late 2024, the world's largest carrot producer became the center of a nationwide food safety crisis. Grimmway Enterprises, Inc., operating as Grimmway Farms, issued a sweeping recall of organic whole and baby carrots after federal investigators linked the products to a multistate outbreak of Shiga toxin-producing Escherichia coli O121:H19. The outbreak ultimately sickened 48 people across 19 states, hospitalized 20, and caused one death in California.

The incident exposed a critical vulnerability in the U.S. fresh produce supply chain: a single supplier's contamination event cascading across more than 18 retail brands sold at virtually every major grocery chain in the country.

Company Overview

Grimmway Enterprises, Inc. is the largest grower, producer, and shipper of carrots in the world. Headquartered in Bakersfield, California, the company processes approximately 10 million pounds of carrots per day and cultivates over 40,000 acres of carrots across its farming operations. In total, Grimmway grows 65 different organic crops on roughly 55,000 acres, producing more than 135 seasonal and year-round products distributed worldwide.

The company was founded as a family operation and grew into a major agricultural enterprise, reportedly generating over $350 million in revenue by 2000. In 2020, the Grimm family sold the business to a private equity firm for an undisclosed price.

Grimmway operates several well-known consumer brands:

• Cal-Organic Farms — One of the largest organic produce brands in the U.S.
• Bunny Luv — Organic carrot brand
• Grimmway Farms — House brand for conventional and organic carrots

Beyond its own brands, Grimmway serves as the upstream supplier for private-label carrot programs at dozens of major retailers, a fact that became painfully clear when a single contamination event rippled across the entire grocery landscape.

Enforcement Timeline

September 6, 2024 — First Illnesses Reported

The earliest illness onset dates in the outbreak trace back to September 6, 2024. At this point, no public connection to Grimmway Farms had been established. Cases began accumulating across multiple states over the following weeks.

November 16, 2024 — Initial Voluntary Recall

After the CDC and FDA identified organic carrots as the likely outbreak vehicle and traced the supply chain back to Grimmway Farms, the company initiated a voluntary recall of select organic whole carrots and organic baby carrots.

The recalled organic baby carrots carried best-if-used-by dates ranging from September 11 through November 12, 2024. Organic whole carrots, which do not carry printed best-by dates, were available at retail from August 14 through October 23, 2024.

November 17, 2024 — CDC Public Alert

The CDC issued a public health alert warning consumers about the E. coli outbreak linked to organic carrots, confirming the connection to Grimmway Farms products.

November 21, 2024 — Recall Expanded

Grimmway Farms expanded the recall to include additional bag sizes for organic whole carrots, broadening the scope of affected products.

November–December 2024 — FDA Inspection

The FDA conducted on-site inspections at Grimmway Farms' Bakersfield, California facility. Investigators collected environmental samples from the facility and surrounding areas. Two environmental samples collected from outdoor areas tested positive for Shiga toxin-producing E. coli (STEC). However, neither environmental isolate matched the O121:H19 outbreak strain. The exact source of contamination was not definitively identified.

December 18, 2024 — CDC Closes Investigation

The CDC declared the outbreak investigation closed with a final count of 48 confirmed cases across 19 states. The implicated farms were out of production, and recalled products had passed their shelf life.

January 8, 2025 — FDA Recall Records Finalized

The FDA finalized five separate recall actions associated with this event, covering the full scope of affected brands, product types, and distribution channels.

The E. coli Outbreak

The Pathogen

The outbreak strain was identified as E. coli O121:H19, a Shiga toxin-producing Escherichia coli (STEC). Unlike the more widely known O157:H7, the O121 serogroup is less commonly associated with large outbreaks but is fully capable of causing severe illness, including hemolytic uremic syndrome (HUS) — a life-threatening condition that can lead to kidney failure.

Case Count and Severity

As of the CDC's final update on December 18, 2024:

Metric	Count
Total confirmed cases	48
States affected	19
Hospitalizations	20 (43% of cases)
Hemolytic uremic syndrome (HUS)	1
Deaths	1 (California)

The 43% hospitalization rate is notably high, reflecting the severity of STEC infections. Illness onset dates ranged from September 6 to November 10, 2024 — a two-month window indicating either sustained contamination or prolonged product shelf life in consumer homes.

Affected States

Cases were reported from 19 states: Arkansas, California, Colorado, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, Texas, Virginia, Washington, Wyoming, and at least one additional state.

Affected Products and Brands

The recall encompassed organic whole carrots and organic baby carrots distributed under more than 18 brand names. Because Grimmway operates as the upstream supplier for private-label programs, the contamination event reached consumers through virtually every major U.S. grocery chain.

Brand	Retailer / Distribution
365	Whole Foods Market
Bunny Luv	National (Grimmway-owned)
Cal-Organic	National (Grimmway-owned)
Compliments	Canadian retailers
Full Circle	Various
Good & Gather	Target
GreenWise	Publix
Grimmway Farms	National
LIDL	LIDL U.S. stores
Marketside	Walmart
Nature's Promise	Ahold Delhaize (Stop & Shop, Giant, etc.)
O Organics	Albertsons/Safeway

Kroger	Kroger
Raley's	Raley's stores
Simple Truth	Kroger
Sprouts	Sprouts Farmers Market
Trader Joe's	Trader Joe's
Wegmans	Wegmans
Wholesome Pantry	ShopRite

The contamination also triggered a secondary recall by 4Earth Farms, LLC of Commerce, California, which recalled organic and conventional vegetable medleys and organic whole carrots containing Grimmway Farms carrots.

Regulatory Response

FDA Actions

The FDA's response included multiple coordinated actions:

1. Traceback investigation: Identified Grimmway Farms as the common supplier through purchase records, distribution data, and shopper card data across multiple retail chains.
2. Facility inspection: Conducted on-site inspection at the Bakersfield, California facility. Collected environmental samples from the facility and surrounding areas.
3. Environmental findings: Two outdoor environmental samples tested positive for STEC, though neither matched the O121:H19 outbreak strain. This suggests the facility's environment harbored pathogenic E. coli, even if the specific outbreak strain was not recovered.
4. Recall classification: The FDA classified the recall at its highest risk level, indicating a reasonable probability that consumption of the product would cause serious adverse health consequences or death.
5. Five separate recall actions were recorded in the FDA Enforcement Reports, reflecting the multiple brands, product types, and distribution channels involved.

Legal Consequences

Multiple class action lawsuits were filed against Grimmway Enterprises, Inc. in late 2024:

• Allegretti v. Grimmway Enterprises (November 27, 2024, California federal court)
• Catalano v. Grimmway Enterprises (U.S. District Court, Southern District of New York)
• Pratt v. Grimmway Enterprises — filed on behalf of a consumer who was hospitalized and tested positive for STEC

The lawsuits allege breach of warranty, negligence, and unjust enrichment. Prominent food safety litigation firms, including Ron Simon & Associates and Milberg, are involved in the cases.

What This Means for the Industry

Supply Chain Concentration Risk

The Grimmway incident is a textbook case of supply chain concentration risk in fresh produce. A single company's contamination event affected 18+ consumer-facing brands across nearly every major U.S. grocery chain. Many consumers purchasing "store brand" organic carrots at Target, Walmart, Kroger, or Trader Joe's had no way of knowing they were all sourcing from the same Bakersfield facility.

Key takeaway for produce companies: Private-label arrangements create hidden single points of failure. When a mega-supplier has a food safety event, the reputational damage cascades to every retailer brand on the shelf.

Organic Produce Is Not Exempt

Organic certification addresses agricultural practices — it does not guarantee pathogen-free products. The Grimmway recall reinforces that organic fresh produce requires the same rigorous food safety controls (environmental monitoring, water testing, field sanitation) as conventional products.

Root Vegetables and E. coli

Carrots present unique food safety challenges. As root vegetables, they grow in direct contact with soil and irrigation water — two primary vectors for STEC contamination. Unlike leafy greens, which have been the subject of extensive FSMA Produce Safety Rule attention following romaine lettuce outbreaks, root vegetables have received comparatively less regulatory scrutiny for STEC risk.

The Detection Gap

Illness onset dates spanned September 6 to November 10, 2024 — over two months — before the recall was initiated on November 16. This detection gap is common in produce-linked outbreaks and underscores the need for proactive environmental monitoring programs and rapid molecular surveillance.

Implications for FSMA Compliance

The Produce Safety Rule under FSMA (21 CFR Part 112) establishes science-based standards for growing, harvesting, packing, and holding of produce. While the specific root cause of the Grimmway contamination has not been publicly disclosed, the incident will likely intensify FDA scrutiny of:

• Agricultural water testing programs for root vegetables
• Environmental monitoring in packing and processing facilities
• Supplier verification programs for retailers using private-label arrangements
• Traceability under FSMA Section 204 (the Food Traceability Rule)
