A new study reveals that the consumption of water beads by young children has skyrocketed in recent years. Analyzing calls to U.S. poison centers, researchers from the Abigail Wexner Institute Injury Research and Policy Center at Nationwide Children’s Hospital and the Central Ohio Poison Center found that reported rates of water bead ingestion among children under 6 increased by a staggering 6,532% from 2019 to 2023, then decreased by 24% from 2023 to 2024.
In a study published today, academic pediatrics, Researchers analyzed six years of data and urged families and caregivers to keep water beads in the house and out of reach of young children.
From 2019 to 2024, 20,279 cases of water bead ingestion by children under 6 were reported to U.S. poison centers. The majority of ingestions occurred in residential settings (95%) and in children under 3 years of age (67%). Most water bead ingestions were not treated in a health facility (80%), but 19% were treated/evaluated and discharged, and 1% were hospitalized. Ingestion was most common in children aged 1 and 2 years, and this finding is consistent with exploratory behavior in this age group.
“Swallowing objects or putting objects in the ear or nose are common behaviors in children, but water beads pose a unique risk of harm due to their expanding nature and are difficult to detect with X-rays,” said Gary Smith, MD, PhD, senior author of the study and director of Nationwide Children’s Center for Injury Research and Policy. “Furthermore, because water beads are sold in sets of tens of thousands, water beads left in the house are likely to go unnoticed until they are found by children, who are known explorers for exploring their environments by putting objects in their mouths.”
Water beads are made from super absorbent material and can expand hundreds of times their original size when exposed to liquid. They have commonly been sold as children’s sensory products, gel projectiles for toy “gel blaster” guns, and decorative items. If swallowed, it can expand in the gastrointestinal tract and cause intestinal obstruction, which can be fatal. It can also cause injury if placed in the ear canal or nose.
Efforts to prevent these ingestions include product recalls by the U.S. Consumer Product Safety Commission (CPSC), the removal of water beads from stores and online by major retailers, and the introduction of federal legislation, specifically the “Water Bead Ban Act” (HR6468) in the U.S. House of Representatives in November 2023 and the “Esther Act” (S.4298) in the U.S. Senate in May 2024. Standards by the CPSC went into effect in March 2026 and established a maximum diameter of 5mm for hydrated water beads, a significant reduction from the previous 20mm, making them less likely to cause intestinal obstruction. It also establishes toxicity testing requirements for water beads.
“Many parents and professionals who work with children are unaware that water beads can be harmful to children,” said study co-author Hannah Hayes, M.D., medical director of the Central Ohio Poison Center. “While we applaud the efforts of many retailers and the new federal regulations, we know that many people who work with children already own and use these products. If you are visiting or visiting children, please do not leave water beads at home. Talk to child care managers, preschool teachers, therapists, and others who may be using water beads with young children to discourage their use.
“Primary prevention of water bead ingestion is of paramount importance given the reported increased overall incidence of water bead ingestion, potential delays in diagnosis, and potential for severe morbidity and mortality,” said Natalie Rein, Pharm.D., co-author of the study and director of the Central Ohio Poison Center. “All healthcare providers should familiarize themselves with the new CPSC regulations regarding water bead safety and continue educating parents and caregivers about the dangers of water beads to keep young children safe.”
Data for this study were obtained from the National Poison Data System (NPDS) maintained by the American Poison Centers. Poison centers receive calls through the National Poison Helpline (1-800-222-1222) and document and report information about exposures to NPDS.
