Check your fridge. Seriously. If you’re a Costco member who buys those massive bags of organic carrots, you might want to stop what you're doing and look at the brand name. Late in 2024, a massive recall hit the shelves involving Grimmway Farms, and Costco was right in the middle of it. This wasn't just some paperwork error or a "maybe" situation. It was a serious E. coli outbreak that actually made people sick across several states.
It's scary. You buy organic because you want to be healthy. You shop at Costco because you trust their quality control. Then, suddenly, the baby carrots you’ve been packing in school lunches for a week are the very thing the CDC is warning you about.
The Reality of the Costco Carrot Recall
The core of the issue stems from Grimmway Farms, one of the biggest carrot producers in the world. They issued a voluntary recall after the CDC and FDA linked their organic whole and baby carrots to a multi-state outbreak of Shiga toxin-producing Escherichia coli (E. coli) O121:H19. This isn't the kind of stomach bug that goes away in twenty-four hours with some ginger ale. It’s a nasty strain that can cause severe bloody diarrhea, stomach cramps, and in the worst-case scenarios, Hemolytic Uremic Syndrome (HUS)—a type of kidney failure.
Costco sold these under the Kirkland Signature label, which is why so many people are concerned. We trust Kirkland. But because Grimmway supplies so many private labels, the recall touched everything from Wegmans and Trader Joe's to Target’s Good & Gather.
Most of the recalled products are likely past their "best if used by" dates now, but the problem is the freezer. A lot of us buy those big bags and freeze them for soups or smoothies. If you have a bag of Kirkland Signature organic carrots sitting in the back of your freezer from October or November 2024, do not eat them. Toss them.
What was actually recalled?
The list is long, but for the Costco crowd, the focus is on the Kirkland Signature Organic Carrots. Specifically, the organic baby carrots that didn't have a specific "best by" date but were sold during a certain window—roughly between September 11 and November 12, 2024.

The whole organic carrots are also on the list. These were sold in bags ranging from 1lb to 25lbs. If you’re the person who buys the 25lb bag of carrots for juicing, you’re at the highest risk simply because of the sheer volume of product you’re handling.
Wait. Why did this happen?
Usually, E. coli in produce comes from contaminated water or runoff from nearby livestock. It’s hard to scrub off because the bacteria can actually get into the microscopic nooks and crannies of the vegetable. Grimmway Farms hasn't pinpointed the exact square inch of soil where this started, but the scale of the recall suggests it was a systemic issue during a specific harvest window.
Symptoms: Knowing if You're Actually Sick
If you ate the carrots, don't panic. Not every single bag was contaminated. But you need to watch your body. Most people start feeling the effects about three to four days after eating the contaminated food.
It starts with severe stomach cramps. Then comes the diarrhea, which often becomes bloody. Some people get a low-grade fever, but the real danger is dehydration. If you're seeing blood, go to the doctor. Don't wait. Honestly, E. coli is one of those things where "toughing it out" at home can lead to permanent kidney damage if HUS sets in.

People ask, "Can I just wash them?"
No.
If E. coli is present on a carrot, especially a peeled baby carrot, washing it in your sink isn't going to do much. The bacteria are resilient. Cooking them to an internal temperature of 160°F ($71^\circ\text{C}$) would technically kill the bacteria, but why risk it? Cross-contamination is the real killer here. You touch the carrot, then you touch the counter, then you touch your sandwich. Now the E. coli is on everything.
Why Costco Members Got Hit Hard
Costco's business model is built on volume. When they stock a product, they stock thousands of units. When a recall happens, the ripple effect is massive compared to a small local grocer. Costco is actually quite good about this, though. They use their membership data to send out automated calls and emails to anyone who purchased the specific item.

The Bigger Picture: Food Safety in 2026
We're seeing more of these outbreaks lately. Or maybe we're just better at tracking them. The CDC uses whole genome sequencing now to link illnesses across the country. They can see that a person in Washington and a person in New York have the exact same "fingerprint" of E. coli, which leads them straight back to the processing plant in California.
It makes you wonder about the "organic" label. Organic doesn't mean "bacteria-free." It just means no synthetic pesticides. In some cases, organic farms use manure as fertilizer, which—if not treated properly—is a prime source for E. coli. It's a trade-off. You're avoiding chemicals, but you're still dealing with biological risks.
How to Handle Your Kitchen Post-Recall
If you realized today that you have the recalled carrots, don't just throw the bag in the trash and call it a day. You have to clean.
Bacteria like E. coli can survive on surfaces for a long time. Use a bleach solution or a high-heat dishwasher cycle for any drawers or containers where the carrots were stored. Wash your hands with warm soap and water for at least 20 seconds. It sounds like basic advice, but it’s the only way to stop the spread within your own home.
Getting Your Money Back
Costco is famous for its return policy. For a recall, you don't even need the physical carrots or the receipt. You can just go to the membership desk, tell them you bought the recalled carrots, and they will pull up your account and issue a refund. They’d rather give you the $6 back than have a lawsuit on their hands.
Actionable Steps for Costco Shoppers
If you’re worried about the carrot recall Costco situation, here is exactly what you need to do right now.
- Identify the bags. Look for Kirkland Signature Organic Carrots (whole or baby).
- Check the dates. If the baby carrots have a "best by" date between Sept 11 and Nov 12, 2024, they are part of the recall. If they have no date but were bought in that window, treat them as contaminated.
- Discard immediately. Do not give them to your pets. Dogs can get sick from E. coli too. Bag them up and put them in the outdoor trash.
- Sanitize your fridge. Take out the crisper drawer. Wash it with hot, soapy water.
- Monitor your health. If you’ve eaten them in the last 10 days, watch for any gastrointestinal distress.
- Visit Costco for a refund. Next time you're there for a $1.50 hot dog, stop by the service desk. They have a record of your purchase.
Food safety is a moving target. While Grimmway Farms has taken the products off the shelves, the investigation into how the contamination happened continues. For now, stay informed, check your labels, and maybe stick to frozen peas for a week while the dust settles.
