Is Konjac Jelly Safe? The Entire Safety History
Konjac jelly is not banned as an ingredient anywhere. The restrictions you may have heard about apply to a specific type of product: small, firm jelly mini-cups that can be squeezed straight into the mouth and create a choking risk. That format caused deaths. Konjac itself is still used in noodles, flour, and soft snacks around the world.
The European Union and Australia banned mini-cup konjac jelly outright. In the U.S., the FDA began warning consumers about it in 2001, after the products were linked to choking deaths, including several involving children. Here's what happened—and how Pac Pac chews fit into that history.
What got banned
The product at the center of this story was the mini-cup jelly candy: a small plastic cup filled with firm, fruit-flavored konjac jelly. It was meant to be squeezed or sucked into the mouth in one motion.
Through the late 1990s and 2000s, these cups were linked to choking deaths among children and older adults. In April 1999, 11-year-old Michelle Enrile choked on an imported mini gel snack in California, fell into a coma, and died in 2001. A jury later awarded her family $16.7 million against the Taiwanese manufacturer (Deseret News, Taipei Times). In 2008, a one-year-old boy in Hyogo Prefecture, Japan, choked and died after eating konnyaku jelly. MannanLife, Japan's largest konnyaku-jelly maker, halted production before returning with a reformulated product and a warning to cut the jelly into pieces.
After earlier incidents, the FDA issued public warnings in 2001, urging consumers not to eat mini-cup gel candies. The agency said the products had been linked to six deaths among children in the U.S.
The European Union and Australia went further and banned the format outright. The FDA, meanwhile, formally recognizes glucomannan—the soluble fiber in konjac—as dietary fiber after reviewing evidence that it can lower LDL cholesterol (FDA, published 2020).
Why the mini-cup format was the problem
The issue was a firm jelly paired with a risky way of eating it. A mini-cup is designed to send the entire jelly into the mouth at once when squeezed. Konjac jelly does not soften or melt in the mouth the way many gelatin candies do.
If the jelly goes down before it can be chewed, it can get stuck in the airway and be hard to dislodge. In Japan, at least 17 people died after choking on konnyaku jelly between 1995 and 2008; most were children or older adults (Japan Times).
Our post on what konjac is explains why glucomannan gives konjac its signature chewy texture.
Is konjac jelly banned in the US?
No. The FDA maintains Import Alert 33-15 (continuously updated by FDA; accessed September 2026), which allows it to detain "mini-cup gel and jelly candies of firm consistency that present a risk of choking."
The alert remains active and targets a particular product format, not konjac as an ingredient. Konjac noodles, konjac flour, soft konjac snacks, and standard-format konjac jelly are sold throughout the U.S.
What other countries did
Regulators around the world have focused on firm mini-cup products, especially cups 45 mm or smaller.
The European Union permanently banned the use of konjac (E425) in jelly mini-cups in 2003 after the format was linked to choking deaths (ConfectioneryNews). Australia permanently bans mini jelly cups containing konjac when they are 45 mm or smaller in height or width (ACCC).
As of April 1, 2026, Hong Kong also prohibits konjac mini-cup jellies 45 mm or smaller. Other prepackaged konjac jelly products must carry a choking warning (Hong Kong CFS).
Why Pac Pac's sachet format is different
Pac Pac chews come in individual sachets. They are chewed in pieces, not squeezed from a sealed cup into the mouth in one go. They are not the 45 mm mini-cup format covered by these bans, and they are not eaten with the suction-based motion that made those products dangerous.
That said, chewy foods still need to be eaten with care. Grapes, hot dogs, hard candy, and chewy jelly can all pose a choking risk for young children. The American Academy of Pediatrics recommends supervising young children while they eat, keeping high-risk foods away until around age four, and cutting firm or round foods into pieces that are easier to chew (AAP, HealthyChildren.org, accessed September 2026).
Does konjac jelly upset your stomach?
Glucomannan is a soluble fiber that absorbs water and swells. Like other high-fiber foods, it can cause gas, bloating, or loose stools if you have a lot at once.
Those effects are more commonly discussed at the higher doses used in fiber-supplement research. A Pac Pac sachet contains about 0.6 g of glucomannan, according to its nutrition information. That's well below the 5 g amounts often discussed in supplement studies, although people can respond differently to added fiber.
Most people can have a few sachets without a problem. If you notice bloating or an upset stomach, try cutting back to one or two servings and see how you feel. If you're having several sachets, drinking water is a good idea, too.
Can you bring konjac jelly on a plane or through customs?
For U.S. airport security, the answer depends on the product's consistency and packaging. TSA allows solid candy in carry-on and checked bags, while foods that count as liquids or gels are subject to the 3.4-ounce carry-on limit. If you're unsure how a particular jelly will be treated, check TSA's current guidance before you fly.
Customs is a separate issue. Some countries restrict specific konjac jelly products, particularly the small, firm mini-cup format—Australia bans mini jelly cups containing konjac, and the European Union has restricted konjac jelly mini-cups (see above). Import rules vary by country and can change, so check the destination country's customs or food-safety authority before packing snacks.
Can dogs eat konjac jelly?
No—it's best to skip it. Konjac jelly products are made for people and aren't formulated as dog treats. The bigger concern is the texture and shape: dogs can swallow pieces without chewing them properly, which can create a choking risk. If your dog eats one and starts gagging, choking, or having trouble breathing, contact a veterinarian promptly.
What we recommend
- Chew thoroughly, every time. Konjac jelly is meant to be chewed, not swallowed whole.
- Supervise young children and older adults. These are the groups named most often in choking warnings.
- Skip old-style mini-cups. If you come across a sealed mini-cup gel candy—especially one without clear U.S. labeling—leave it on the shelf.
- Drink water with it, especially if you're having more than one serving.
