Dollar stores have become part of everyday American shopping. According to a 2024 Mintel report, nearly nine in ten adults shopped at dollar store discounters in the previous year. That’s a remarkable number, and it reflects a real economic reality for millions of families. Inflation has pushed people toward any deal they can find.
Still, not everything on those shelves is worth picking up. From a food science standpoint, certain categories carry risks that simply aren’t obvious from the price tag. Here are six items that anyone with a working knowledge of food safety and chemistry should think twice about before tossing in their cart.
1. Canned Goods with Unknown Interior Linings
Canned goods seem like the obvious safe pick at a dollar store. They’re shelf-stable, sealed, and familiar. The problem isn’t the food inside so much as what coats the can itself.
Several canned food items sold at major dollar store chains, including Dollar Tree and Dollar General, were found to contain toxic interior coatings, including BPA-based epoxy and PVC can body coatings. That’s not a minor concern. BPA is a toxic, endocrine-disrupting chemical that negatively impacts hormonal systems, and hundreds of scientific studies have linked even extremely small amounts to increased risk of breast and prostate cancer, infertility, type-2 diabetes, obesity, asthma, and behavioral changes including attention deficit disorder.
Progress on eliminating epoxy resin can linings has been uneven, and food cans with epoxy linings are more commonly found in ethnic and discount stores serving low-income communities. The 2024 Mind the Store Retailer Report Card confirms this slow progress. Dollar Tree earned a D rating, noting that while the company has a chemical policy, it has expanded it to include more restricted substances only in recent years.
2. Ground Cinnamon and Spice Blends
Cinnamon and spice blends feel like a harmless budget buy. They’re dry goods, they last a long time, and the price difference seems to make no sense. But the safety record here is genuinely troubling.
The FDA recommended a voluntary recall from Dollar Tree and Family Dollar in 2024 for lead-containing cinnamon products and fruit purée pouches, noting that unsafe levels of lead are especially dangerous for children under six, even in small amounts. This wasn’t a routine quality complaint. The FDA, along with the CDC and state partners, investigated elevated levels of lead linked to consumption of WanaBana Apple Cinnamon Fruit Purée pouches, and laboratory analysis of multiple lots, including samples collected from Dollar Tree stores, detected extremely high concentrations of lead.
The FDA sent a warning letter to Dollar Tree in 2024 for failing to effectively remove these fruit purée products from store shelves weeks after being notified of the recall, and the agency openly questioned whether the retailer has the capability to quickly act on FDA notices following a series of unsuccessful recall audit checks. For cinnamon specifically, the pattern is consistent and documented. Sourcing at this price point comes with real verification gaps.
3. Cooking Oils and Olive Oil Blends
Cooking oil at a dollar store sounds like a practical win. It’s one of the most used items in any kitchen, and the savings seem real. The issue is what’s actually in the bottle.
Getting cooking oil at the dollar store is broadly not recommended, because these products are typically blends with usually less than five to ten percent of the actual named oil, and the rest is soybean oil. From a food science standpoint, that matters a great deal. What you think you’re cooking with and what you’re actually cooking with can be very different things, with different smoke points, different fatty acid profiles, and different flavor impacts on your food.
Labels at this price point often rely on the kind of framing food scientists call a “health halo.” Dollar store food products are subject to FDA labeling requirements, but not everything on food packages is regulated by the agency. Manufacturers use colorful images, product names, and claims that give food a health halo, meaning claims like “made with real olive oil” could mislead buyers even if they’re not technically incorrect.
4. Baby Food and Toddler Snacks
This one is perhaps the most sensitive category on this list. Parents shopping on a tight budget may see baby food pouches and toddler snacks at dollar stores as a relief. The reality demands more caution.
Lead exposure has been linked to a host of debilitating health effects, especially in young children, where it can cause developmental issues, behavioral problems, and cognitive impairments. The lead contamination in recalled products led to over 500 children becoming ill from consuming tainted products, and even as the illness count rose, tainted products remained on store shelves months after the recall notice had been issued.
Avoiding perishable food, pet food, and baby items at dollar stores is a common recommendation from consumer finance experts, as they can be especially risky. The combination of uncertain supply chains, slow recall responses, and the particular vulnerability of young children makes this a category where the potential cost of getting it wrong is simply too high.
5. Microwavable Popcorn
Microwavable popcorn is a dollar store staple. It’s cheap, it’s popular, and it’s the kind of snack that seems completely harmless. The packaging, though, has been a documented concern.
Testing by the Campaign for Healthier Solutions found PFAS chemicals in the packaging coating of every single item of microwave popcorn tested from major dollar store chains. PFAS, sometimes called “forever chemicals,” don’t break down easily in the body or the environment. There is some positive news: more recent test results suggest that microwaveable popcorn packaging sold at dollar stores is now free of PFAS. Still, the improvement is recent and the track record warrants ongoing scrutiny from any food safety perspective.
Many items at dollar stores, particularly snack foods, processed goods, and sugary beverages, are not necessarily the healthiest options, and microwavable popcorn tends to carry high sodium and artificial flavoring loads on top of the packaging chemistry questions. It’s a category where the savings rarely outweigh the accumulated concerns.
6. Perishable Meat and Refrigerated Items
Frozen and refrigerated meat at dollar stores is a real risk that goes beyond simple quality concerns. The cold chain, meaning the unbroken sequence of refrigerated handling from production to sale, is harder to guarantee at a high-volume, lower-staffed discount retailer.
Some dollar stores aren’t fully dedicated to ensuring perishables haven’t already expired, and in March 2024, a Family Dollar store in Boston was found selling items like pasta sauce, pancake mix, and turkey breast far beyond their sell-by dates. That’s a real, documented example, not a hypothetical. Damaged or dirty packaging is also a known issue, and a dollar store truck driver reported that it’s common for trailers fully loaded with food to sit for weeks before making deliveries to stores.
In 2025, a Dollar Tree in North Providence, Rhode Island, was forced to temporarily shut after inspectors found evidence of severe rodent infestation, including droppings, nesting materials, and rat corpses scattered throughout the store, even among shelved inventory. Rodent contamination in a store environment where refrigerated meat is sold creates serious food safety risks that are simply not worth taking.
The Broader Picture on Dollar Store Food Safety
Dollar stores are held to the same regulatory requirements for safety as every business that sells food, but some companies have struggled to uphold these laws. The gap between what the regulations require and what actually happens on the ground is where the real risk lives. Regulatory frameworks only work when enforcement is consistent and retailers respond quickly to violations.
Of the 226 consumer and food products tested at Dollar Tree, Family Dollar, Dollar General, and other major discount chains, more than half of the products screened contained one or more chemicals of concern. That figure comes from a comprehensive 2022 screening report by the Campaign for Healthier Solutions and the Ecology Center Healthy Stuff Lab. It’s the kind of data point that doesn’t disappear just because store counts are growing or prices look attractive.
What Dollar Stores Are Doing About It
To be fair, the situation isn’t entirely static. Some policy commitments have been made. Dollar Tree did update its priority chemical policy, committing to eliminating the use of phthalates and forever chemicals like PFAS in the company’s private-brand food and beverage product packaging. Those are real steps, even if the scope remains limited to private-label products.
In May 2024, representatives of the Campaign for Healthier Solutions attended Dollar General’s annual shareholders meeting urging the company to commit to eliminating chemicals of concern from its supply chain, but after the company failed to make any new commitments, the campaign announced it was actively testing Dollar General products for chemicals linked to cancer, learning disabilities, and reproductive harm. Progress is uneven and advocates remain unconvinced.
How to Shop Smarter If You Do Go
Paper products, party and craft supplies, and storage containers are among the best deals at dollar stores. The food aisle is where care is most needed. Checking expiration dates closely is essential, especially for anything refrigerated or packaged.
One key consideration when purchasing food from dollar stores is ensuring products are within their expiration date, and while stock is regularly rotated, some customers have reported finding expired food products on shelves, particularly for canned goods and dry snacks. Experts also recommend choosing fresh or frozen foods over canned where possible, or only purchasing canned food from manufacturers that fully disclose the identity and safety of their can linings, and looking for food packaged in glass or Tetra Pak containers when canned goods are unavoidable.
The Six Items at a Glance
To summarize what the evidence actually supports: canned goods with opaque lining information, ground cinnamon and spice blends, cooking oil or olive oil blends, baby food and toddler snacks, microwavable popcorn, and refrigerated or frozen meat are the six categories where the documented risks are clearest. Each one has a paper trail of recalls, chemical testing, or inspection reports that justifies the caution.
None of this is about stigmatizing budget shopping. With more than 35,000 dollar stores nationwide, this business model is thriving, especially during this era of elevated inflation, and millions of people rely on these stores out of necessity. The goal of any food scientist looking at this data isn’t to shame a shopping choice. It’s to make sure the people making that choice know what the tradeoffs actually are.
A Final Word on Knowing Your Risk
Food safety isn’t about perfection. It’s about probability and exposure over time. Buying a can of beans once is unlikely to cause harm. Regularly buying from a store that has a documented history of slow recall responses, chemical-laden packaging, and inconsistent cold chain management is a different calculation entirely.
The six items listed here aren’t arbitrary. Each one sits at the intersection of documented hazards, vulnerable populations, or both. Spending a little more at a mainstream grocery store for these specific categories is, from a food science standpoint, a straightforward investment in the one thing that no discount can replace: your long-term health.
