New State Laws Are Forcing Baby Food Makers to Test for Heavy Metals—Here's What Parents Need to Know

Two states have enacted groundbreaking legislation requiring baby food manufacturers to test finished products for toxic heavy metals and make results publicly available to parents. Maryland's "Rudy's Law" and Virginia's "Baby Food Protection Act," both enacted in late 2025 and early 2026, represent a major shift in how the baby food industry is regulated—and they're happening as nearly 400 lawsuits remain pending against Walmart and other manufacturers over heavy metal contamination.

What Are These New State Laws Requiring?

Maryland and Virginia have taken different but complementary approaches to protecting infants from heavy metal exposure through contaminated baby foods. Both laws mandate that manufacturers test their finished baby food products and share the results with consumers, marking a significant change in transparency and accountability.

• Maryland's \"Rudy's Law\": Requires commercial baby food manufacturers to test for heavy metals and provide consumers with scannable labels on baby food containers that direct them to a webpage displaying the test results for each product.
• Virginia's \"Baby Food Protection Act\": Mandates that manufacturers test finished baby foods for four specific toxic heavy metals and make test results available online to parents and consumers, while prohibiting the sale of foods that exceed FDA guidance levels for heavy metal contamination.
• Enforcement Mechanism: Both laws prevent companies from selling baby foods that exceed established heavy metal safety thresholds, creating a legal requirement for compliance rather than voluntary industry standards.

Maryland's law was named after Rudy Callahan, a toddler who was poisoned by lead in applesauce pouches he consumed as a baby. His mother, Sarah Callahan, championed the legislation to prevent other families from experiencing similar harm from preventable contamination.

Why Are These Laws Necessary Right Now?

The timing of these state laws reflects growing concern about heavy metal contamination in baby foods and the lack of federal action. Heavy metal exposure in infants has been linked to neurodevelopmental disorders, including autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). A February 2026 scientific literature review titled "Concentrations of Heavy Metals in Processed Baby Foods and Infant Formulas Worldwide: A Scoping Review" called for more rigorous product testing and stricter safety standards to protect infant health and well-being.

Currently, the FDA does not set specific limits on heavy metals in baby foods, leaving manufacturers with significant discretion in testing and disclosure practices. This regulatory gap has allowed some products to reach store shelves with levels of contamination that concern health advocates and parents alike.

What's Happening in the Walmart Lawsuits?

As of February 2026, there are 389 pending lawsuits consolidated into federal multidistrict litigation (MDL No. 3101) against Walmart and other baby food manufacturers. Parents filing these lawsuits allege that Walmart's Parent's Choice brand baby foods contained dangerous levels of heavy metals that caused their children to develop autism, ADHD, and other neurodevelopmental conditions.

The litigation has faced significant legal hurdles. In late February 2026, U.S. District Judge Jacqueline Scott Corley excluded most of the plaintiffs' expert testimony, allowing only testimony from Dr. Shapiro to move forward—a ruling that has major implications for the strength of the remaining cases. Additionally, Walmart received a warning letter from the FDA in December 2025 for its slow response to a contaminated infant formula recall, during which the company continued selling formula that may have been contaminated with Clostridium botulinum, a bacterium that can cause infant botulism.

How to Protect Your Baby from Heavy Metal Exposure in Food

• Check Product Labels: Look for scannable labels on baby food containers (now required in Maryland) that direct you to online test results showing heavy metal levels, and verify that products comply with FDA guidance on safe contamination thresholds.
• Diversify Food Sources: Rotate different brands and types of baby foods rather than relying exclusively on one product or manufacturer, which can reduce cumulative exposure to any single source of contamination.
• Consult Your Pediatrician: Ask your child's doctor about the safest baby food options for your infant and whether your state's new laws apply to products you're currently using, especially if you live in Maryland or Virginia.
• Stay Informed About Recalls: Monitor FDA recall announcements and check whether products you've purchased are included in any safety alerts related to heavy metal or bacterial contamination.

What Does This Mean for Parents Going Forward?

The passage of these state laws signals that parents and lawmakers are no longer willing to accept the status quo of limited transparency around heavy metal contamination in baby foods. While Maryland and Virginia have taken the lead, other states may follow with similar legislation. For parents outside these states, the laws underscore the importance of asking manufacturers directly about their testing practices and demanding transparency about product safety.

The ongoing litigation and new state regulations are also likely to pressure the FDA to establish federal standards for heavy metal testing and disclosure in baby foods. Until that happens, parents should remain vigilant about which brands they choose and advocate for stronger protections in their own states.
