Romaine lettuce is one of the most popular greens in America. It shows up in Caesar salads, wedge salads, wraps, burgers, and just about every restaurant menu you can think of. But here’s the thing most people don’t realize: not all romaine is created equal, and the label on that bag or that head of lettuce tells you way more than you think. In fact, in late 2024, 89 people across 15 states got sick from contaminated romaine, 36 ended up in the hospital, and one person died. The kicker? The FDA never told the public which company grew it. Federal lawsuits eventually pointed to Taylor Farms as the source, but by then the investigation was already closed.
So what should you actually be checking before you eat romaine? The label. Specifically, where it was grown, when it was harvested, and how it was produced. This isn’t about being paranoid. It’s about being smart with a product that has a well-documented track record of problems. Let’s rank the major romaine lettuce options from worst to best, so you know exactly what to grab and what to skip.
7. Unlabeled Bulk Romaine From the Produce Bin (Worst)
This is the romaine you see piled up loose in the produce section with no sticker, no label, and no indication of where it came from. Some grocery stores still sell whole heads of romaine this way, and it’s the absolute worst option you can pick.
Here’s why. Since 2018, the FDA and the produce industry have pushed for voluntary “provenance labeling” on romaine, meaning the package or sticker should tell you the growing region. According to the United Fresh Produce Association, if you can’t identify the harvest region, you shouldn’t eat the romaine. Period. That guidance came straight from the FDA during previous outbreak investigations.
When romaine is sitting in a bulk bin with zero traceability, you have no idea if it came from a region with known contamination issues, when it was harvested, or who grew it. The CDC has explicitly said that if you have romaine without harvest region information, you should throw it away. Unlabeled bulk romaine is a total mystery, and there’s no reason to gamble when better options exist.
6. Taylor Farms Romaine and Romaine Blends
Taylor Farms is one of the biggest produce companies in the country. They supply romaine and lettuce blends to restaurants, caterers, schools, and grocery stores nationwide. And right now, they’re at the center of a major controversy.
Federal lawsuits filed in April 2025 named Taylor Farms as the grower of the romaine lettuce linked to the November 2024 E. coli O157:H7 outbreak. That outbreak sickened 89 people in 15 states, hospitalized 36, caused kidney failure in 7 (including two children), and killed one person. Three of the lawsuits were filed on behalf of victims who developed hemolytic uremic syndrome, which is acute kidney failure.
Taylor Farms denied being the source, stating that their testing showed no evidence of contamination. But attorney Bill Marler, who has been litigating food contamination cases for decades, says the FDA’s own traceback investigation confirmed Taylor Farms romaine as the source. The company was also previously identified as the supplier of the slivered onions behind the McDonald’s Quarter Pounder E. coli outbreak in fall 2024, which sickened 104 people across 14 states.
Two major outbreaks linked to one company in the same year is a pattern you should pay attention to. The problem is that Taylor Farms supplies a lot of the bagged salad blends and foodservice lettuce you encounter at restaurants and catering events, so you might be eating their product without even knowing it. If you’re buying bagged salad at the grocery store, flip the package over and check who produced it.
5. Generic Store-Brand Bagged Romaine Blends
Most major grocery chains sell their own store-brand bagged romaine, romaine hearts, and romaine blends. Think of the generic label at your local supermarket. These products are almost never grown by the retailer. They’re sourced from large-scale growers and processors, often the same companies that supply the name brands.
The issue with generic store-brand romaine is transparency. While most of these bags do include a growing region (which is good), they rarely make it easy to trace the product back to a specific farm or grower. Food safety professionals have noted that centralized washing and processing of large batches means one contaminated head can spread problems to an entire lot. When you don’t know who actually grew the lettuce inside a generic bag, you’re relying entirely on the retailer’s supply chain to have done its homework.
These aren’t terrible. They’re just a middle-of-the-road gamble. Always check for the growing region, the harvest date (or use-by date), and make sure the bag has been stored at or below 41 degrees Fahrenheit.
4. Dole Romaine Hearts and Blends
Dole is one of the most recognizable names in produce, and their romaine products are everywhere. They generally do a good job with labeling, including harvest region information on their packages. That alone puts them ahead of unlabeled options and some generic brands.
Dole’s romaine hearts are usually sourced from the Salinas Valley in California during summer and fall, and from the desert regions of Arizona and California during winter months. These are the same growing areas that have been involved in past contamination events, which is worth knowing. A peer-reviewed study found that 52 percent of E. coli contamination in romaine comes from untreated overhead irrigation water, and that risk can be cut by up to 96 percent through water treatment or switching to drip irrigation. Large-scale growers like Dole have invested in improved agricultural water practices, but the field-growing model still carries inherent risk compared to indoor alternatives.
Dole lands in the middle of the pack. Solid labeling, wide availability, reasonable price, but still field-grown in regions with a documented history of issues.
3. Fresh Express Romaine
Fresh Express is another major player in the bagged salad space, and they’ve made notable investments in food safety over the years. Their romaine products typically include clear provenance labeling and use-by dates, and they operate processing facilities with sanitation protocols that go beyond the legal minimum.
What puts Fresh Express a notch above Dole in this ranking is their adoption of more advanced testing and processing technology. They’ve also been more responsive to public pressure around transparency after their own past controversies. That said, Fresh Express romaine is still field-grown in the same major growing regions, so it shares many of the same baseline risks. You’re getting better traceability and quality control, but you’re still in the world of conventionally farmed romaine.
Check the label for the growing region and harvest date, and you’re in decent shape. It’s a reliable option for everyday use.
2. Local Farm Romaine (Farmers Markets and Local Suppliers)
If you have access to a farmers market or a local farm stand that sells romaine, this is a significantly better option than anything you’ll find in a bag at a big box store. The reason is simple: short supply chains. You can literally ask the farmer where and how the lettuce was grown, what water source they use, and when it was harvested.
The FDA has noted that romaine requires protection from contamination during every stage from farm to table, and a shorter chain with fewer processing steps and no centralized washing facility means fewer opportunities for cross-contamination. Small-scale farms also tend to use less overhead spray irrigation, which is the single biggest contamination vector according to research.
The downside? Availability is seasonal and regional. You can’t always get local romaine in January. And it costs more. But when it’s in season, this is one of the best choices you can make.
1. Hydroponically or Greenhouse-Grown Romaine (Best)
This is the winner, and it’s not even close. Hydroponically and greenhouse-grown romaine, sometimes labeled as “indoor grown,” has a fundamentally different risk profile than field-grown romaine. The CDC has stated clearly that hydroponically and greenhouse-grown romaine from any region does not appear to be related to the field-grown outbreaks that have plagued the industry.
Brands like Gotham Greens, Little Leaf Farms, Revol Greens, and BrightFarms all sell indoor-grown romaine and leafy greens. These companies grow lettuce in controlled environments where the water is filtered, there’s no contact with soil or wild animals, and contamination from irrigation runoff is essentially eliminated. The United Fresh Produce Association’s labeling guidelines specifically note that indoor-grown romaine should carry that designation on the package, making it easy to identify.
Indoor-grown romaine is usually crisper, lasts longer in the fridge, and tastes noticeably fresher because it doesn’t spend days in a truck crossing the country. Yes, it costs a little more. A clamshell of hydroponically grown romaine might run $3.99 to $4.99 versus $2.99 for a bag of conventional romaine hearts. But when you factor in the drastically lower risk and the better flavor and shelf life, it’s the smartest buy in the produce aisle.
The Bottom Line: Always Check Before You Eat
The November 2024 outbreak proved something alarming: federal agencies don’t always tell you when something goes wrong with your food. The FDA closed its investigation without naming the company involved, without issuing a public warning, and without a recall. It took private lawsuits to surface the truth months later.
That means the responsibility falls on you. Every single time you pick up romaine lettuce, flip the package and look for three things: the growing region, the harvest or use-by date, and whether it says “indoor grown.” If it doesn’t have a growing region listed, put it back. If you’re at a restaurant and they’re serving romaine in a salad, it’s worth asking where they source it.
Attorney Bill Marler summed it up perfectly: “For me to eat romaine lettuce that the FDA has decided we don’t have a right to know who grew, it just doesn’t make sense to me.” He’s right. Until the system gets more transparent, reading the label is the single most important thing you can do before eating romaine lettuce.
