California's ADDE Act requires chain restaurants to disclose the top 9 allergens on menus from July 1, 2026. Here's what QSR operators need to know – and why the whole US food sector and beyond should be paying attention.
In October 2025, the state of California introduced the Allergen Disclosure for Dining Experiences Act (SB 68), a new landmark legal standard for allergen disclosure in the US.
Know as the ADDE Act for short, it comes into force on July 1, 2026, and requires all large restaurant chains to disclose the top nine major food allergens on their menus.
California is the first US state to enact such a change, which has come about through calls from campaigners and broad bipartisan backing. There is now a push for more US state legislatures to follow suit.
Its adoption forms part of a wider global trend too. Many other national authorities, including those in the UK and EU, have already adopted far tougher allergen labelling food service legislation.
For US QSR operators – and the broader foodservice supply chain – the ADDE Act restaurant compliance deadline on July 1 2026 should act as a clear line in the sand. It will set in motion stringent new protocols across the food network, as the industry prepares for what looks set to be the new status quo.
Designed to improve convenience, accessibility and safety for the approximately 33 million people living with a food allergy in the US, the ADDE Act requires QSR operators to proactively disclose major allergens on menus.
Compliance with the ADDE Act will be enforced by the California Department of Public Health and local health agencies, via routine visual inspections.
Far from a straightforward addition to menus, these new rules on allergen disclosure look set to add numerous new complexities for QSR operators.
For larger QSR chains, often offering hundreds of menu items provided by multiple suppliers and subject to frequent item changes or LTOs (limited-time offers), ensuring that allergen data remains accurate, updated and visible across both physical and digital menus presents a significant operational challenge. For example, reformulation by a single supplier could create a compliance gap overnight and leave the business exposed to legal action.
For operators with a restaurant network that spans hundreds, if not thousands of locations across multiple US states, the logistics of updating physical menus each time there’s an update or reformulation represents both a logistically and financially demanding exercise. Even where chains opt to rely on a primarily digital menu (using either QR codes or online allergen charts) it creates a new layer of technology, requiring investment but also teams to handle data input and its integration with any existing software or technology stack.
Compliant menus should be regarded as the baseline for allergen disclosure at US QSR sites, with clear and informed communication from front-of-house staff still an imperative part of ensuring that allergy sufferers feel safe and supported. From a legal standpoint, though the ADDE Act itself doesn’t mandate verbal communication, operators could still be liable if written information is misleading or staff give contradictory guidance when asked. As a result, operators will need to prioritise comprehensive allergen awareness training for all staff, with any menu or ingredient updates proactively circulated to teams.
Industry bodies, such as the California Restaurant Association, raised concerns during the passage of the ADDE Act about its potential to spark predatory litigation, targeting QSR operators that make minor mistakes. While the Act itself limits penalties to existing health code fines, allergen non-disclosure that leads to a series adverse reaction could expose restaurant chains to a civil liability risk, with a far higher ceiling on potential pay-outs. Mitigating this legal risk could leave operators with additional cost and a hefty administrative burden, some have warned.
Those QSR operators that approach the requirements of California’s ADDE Act as a standalone compliance exercise risk being caught off-guard.
Though California is the first US state to enact such a change, it’s part of a global push toward more transparent labelling that is set to impact all restaurant chains’ networks, regardless of where they’re located, in the coming years.
So, will the California allergen law spread to other states? Yes, is the short answer.
In the US, advocacy groups say they’re already in conversations with lawmakers in several other states, labelling the Californian bill as a “foundation to build on” rather than a finish line for their efforts.
There are already bills on the table in Michigan, New Jersey and Maryland, with some of the proposed legislation in these states going even further than the ADDE Act in scope, placing requirements on all restaurants.
But it goes beyond that. Outside the US too, a number of national and federal authorities have enacted similar changes – or are in discussions to do so.
Under EU Regulation No 1169/2011, all restaurants and food service businesses must already provide clear and accurate information if any of the 14 major allergens are used as ingredients in food and drink served.
In 2021, via Natasha’s Law, the UK went further, extending this disclosure requirement to pre-packed foods too. The law requires any business making and packaging food on the same premises where it is sold (known as Pre-Packed for Direct Sale) including restaurant chains to print a full ingredient list on packaging with all 14 major allergens emphasised in bold.
In short, this isn’t a regional shift confined to California, it’s an international step change in what’s expected of allergen labelling across QSR throughout the United States and beyond.
To meet new food allergen disclosure standards for chain restaurants, QSR operators won’t be able to act alone.
Instead, they’ll need to work collaboratively with suppliers and manufacturers within their ecosystem to ensure information is shared accurately, swiftly and proactively. If they don’t they risk missing allergens that the ADDE Act deems they should ‘know or reasonably should know’ are present.
Informal relationships or ad hoc updates between operators and manufacturers won’t be sufficient to meet this higher benchmark. Instead, manufacturers will need to formalise allergen data flows to their QSR customers – including proactive notifications of any recipe or ingredient changes, batch-level traceability and the creation of standardised spec sheet formats.
Though not directly liable under the ADDE Act, failure to make these changes could see manufacturers indirectly expose their QSR customers to legal risk, damaging crucial commercial relationships and eroding their own competitiveness.
With the restaurant allergen menu requirements in the US now carrying legal force, all QSR operators within scope must be 100% compliant with California’s ADDE Act as of July 1, 2026.
The tide is turning on allergen disclosure for US restaurant chains. If food allergy transparency in restaurants once placed minimal demands on operators, California's food safety law in 2026 marks a turning point – with mounting pressure from customers, campaigners and regulators to raise the bar.
It’s also the first of many similar legislative changes in the works, both inside and outside the US. That’s why, those businesses that will navigate the legislation’s introduction best will be those that use it as a jumping off point for broader change in how they approach allergen disclosure, rather than a standalone exercise.
