Fourteen out of twenty-one popular kids’ snacks tested positive for concerning levels of chemical contaminants, according to a new Consumer Reports investigation.
Story Snapshot
- Consumer Reports tested 21 packaged snacks marketed to kids and found 14 had worrying levels of at least one contaminant.
- Acrylamide, a probable human carcinogen, turned up in 13 of 14 products tested for it, including granola bars, chips, and crackers.
- Three products exceeded the group’s phthalate concern threshold by name: Annie’s Organic Cheddar Bunnies, Slim Jim Mild Snack Size Sticks, and Clif Zbar Chocolate Chip.
- Heavy metal levels stayed low across most products, a bright spot in an otherwise troubling report.
What Consumer Reports Actually Tested For
Consumer Reports sent 21 snacks popular with kids to a lab for screening. Testers checked for five contaminant types: acrylamide, phthalates, glycidyl esters, 3-MCPD, and heavy metals like lead and cadmium. The snacks ranged from crackers and chips to granola bars, yogurt, and fruit snacks. Every product got checked for heavy metals and phthalates, while select items also underwent testing for the other three chemical classes.
The results split products into two camps. Some snacks stayed well below concern thresholds. Others crossed lines that made Consumer Reports flag them directly to parents. Jessica D’Argenio Waller, who worked on the investigation for Consumer Reports, said plainly that 14 of the 21 snacks tested carried concerning levels of at least one chemical contaminant, including acrylamide or phthalates.
Acrylamide Showed Up Almost Everywhere It Was Checked
Acrylamide forms naturally when starchy foods get fried, roasted, or baked at high heat. It showed up in 13 of the 14 products tested for it, spanning granola bars, chips, pretzels, and graham crackers. The Food and Drug Administration (FDA) classifies acrylamide as a probable human carcinogen based on animal studies, though the agency has not banned it outright and continues developing guidance for reducing levels in food production.
Phthalates told a narrower story. Ten of the 21 products had measurable levels, but only three crossed Consumer Reports’ concern line. Phthalates are chemicals used to make plastics flexible, and the FDA allows nine of them in food packaging materials even though they are not approved for direct addition to food. That gap between packaging rules and what actually migrates into food is part of why these chemicals keep surfacing in snack testing.
Heavy Metals Stayed Mostly Under Control
Parents worried about lead and arsenic got some relief from this round of testing. Consumer Reports did not find concerning levels of either metal in the products checked, and only one item carried enough cadmium to register as a concern. That tracks with earlier Consumer Reports baby food testing, which found 96 percent of products tested came in below the group’s risk threshold for heavy metals.
Why This Keeps Happening to Foods Marketed at Kids
Consumer Reports has pushed on food safety for children before. The group spent years lobbying the FDA to ban Red Dye 3, a dye tied to cancer in animal studies and used in candy and snacks marketed to kids. The FDA announced that ban in January 2025. This snack testing fits the same pattern: advocates set their own concern thresholds while formal regulatory limits for many of these contaminants remain incomplete or nonexistent, leaving parents to sort out risk largely on their own.
Parents reading this report will likely land on a simple conclusion: companies selling food to children should carry the burden of proof, not the other way around. When a probable carcinogen shows up in 13 of 14 tested products, that is not a rounding error. It is a signal that voluntary industry standards alone are not getting the job done, and that common-sense labeling and sourcing changes should not wait for a lawsuit to force them.
Consumer Reports tested 21 of the most popular kids' snacks. 14 came back with harmful contaminants above CR's level of concern.
The worst three were Annie's Organic Cheddar Bunnies, Clif Zbar and Gimme Roasted Seaweed.

Consumer Reports framed its testing as a tool for comparison, not a verdict that every flagged snack is unsafe to eat occasionally. The group’s own writeup noted it designed the analysis to identify products with comparatively higher contaminant levels relative to others in the same category, giving parents a way to choose better options rather than a reason to panic over every lunchbox item.
