Who regulates pet food
Pet food in the United States is regulated by FDA, primarily through its Center for Veterinary Medicine, under the Federal Food, Drug, and Cosmetic Act, which treats food for animals as food. States also regulate pet food. Most states have adopted versions of the model feed bill and regulations published by the Association of American Feed Control Officials (AAFCO), and state feed control officials enforce labeling and product registration requirements.
AAFCO itself is not a regulator. It is an association of state and federal officials that develops model rules and ingredient definitions. When people say a food meets AAFCO standards, they usually mean it meets nutrient profiles or feeding trial protocols described in AAFCO's publications, which states adopt into their own rules.
This guide focuses on the parts of federal law that affect storage and distribution. It is general information, not legal advice, and you should confirm your obligations with qualified regulatory counsel.
Food facility registration
Facilities that manufacture, process, pack or hold food for consumption in the United States, including food for animals, are generally required to register with FDA. That includes many warehouses and distribution centers that hold pet food. Registrations must be renewed every two years, during the October to December window of even-numbered years.
There are exemptions, for example for certain retail food establishments and farms, but a third-party warehouse holding pet food for distribution is typically within scope. When evaluating a 3PL, it is reasonable to ask whether the facility that will hold your product is registered. Registration does not mean FDA has approved or certified the facility; it means FDA knows the facility exists and can contact it, which matters during inspections and outbreaks.
FSMA and the animal food rule
The Food Safety Modernization Act, signed into law in 2011, shifted FDA's approach from responding to contamination toward preventing it. For pet food and other animal food, the central regulation is the rule on Current Good Manufacturing Practice, Hazard Analysis, and Risk-Based Preventive Controls for Food for Animals, found at 21 CFR Part 507.
The rule has two main layers. The first is current good manufacturing practices, which set baseline expectations for things like personnel hygiene, plant and grounds, sanitation, pest control, equipment and holding conditions. The second is hazard analysis and risk-based preventive controls, which apply mainly to manufacturers and processors.
For warehouses, the details matter. A facility solely engaged in storing packaged animal food that is not exposed to the environment is generally exempt from the hazard analysis and preventive controls requirements. However, modified requirements apply when that packaged food requires time and temperature control for safety, such as monitoring temperatures and taking corrective action when they go out of range.
What good holding practice looks like
Even where the full preventive controls requirements do not apply, the expectation is that animal food is held under conditions that protect against contamination and minimize deterioration. In a fulfillment operation, good holding practice typically includes:
- Clean, dry storage areas with regular sanitation schedules.
- An integrated pest management program with documented service and monitoring.
- Segregation of pet food from chemicals, pesticides and other potential contaminants.
- Procedures for damaged packaging, spills and leaking product.
- Receiving inspections for damage, moisture and pest activity.
- Temperature monitoring and records for products that require it.
- Lot and date tracking that supports traceability.
These are the practices you should expect to see when you tour or audit a 3PL. Ask to see the pest control service log and sanitation schedule; a well-run operation will have them ready.
Sanitary transportation
FSMA also includes the Sanitary Transportation of Human and Animal Food rule, which applies to shippers, loaders, carriers and receivers involved in transporting food by motor vehicle or rail in the United States. Its aim is to prevent practices that create food safety risks during transport, such as failing to properly refrigerate food that needs it, inadequate cleaning of vehicles between loads, or failing to protect food from contamination by non-food items.
For pet brands, the practical implications are mostly about temperature-controlled products and mixed loads. Frozen raw and fresh-cooked pet foods require appropriate temperature control and documentation through transit. Dry pet food and treats should not share trailers with products that could contaminate them. When a 3PL books freight on your behalf, ask how they communicate sanitary and temperature requirements to carriers.
Recalls and reportable food
A recall is usually initiated by the brand, sometimes at FDA's request. FDA also operates the Reportable Food Registry, which requires responsible parties for registered food facilities, including those holding animal food, to report when there is a reasonable probability that an article of food will cause serious adverse health consequences, generally within 24 hours of making that determination.
The fulfillment partner's role in a recall is to supply facts fast and control stock. That means identifying every order that received an affected lot, the customers and ship dates, and the units still on hand, then placing those units on hold across every location and channel. A 3PL with lot-to-order traceability can do this in minutes. Without it, brands often have to recall far more product than necessary because they cannot narrow the scope.
What stays with the brand
Outsourcing fulfillment does not transfer your regulatory responsibilities as a pet food brand. You remain responsible for product formulation and safety, label content and claims, nutritional adequacy statements, state product registrations and licensing, supplier approval, and decisions about recalls and regulatory reporting.
A good 3PL complements that work. It protects the product while holding it, keeps records that support your compliance program and responds quickly when you need data. When you onboard, share your recall plan and contacts, agree how holds and releases are communicated, and run a mock trace so you know how fast you can get lot-to-order data before you ever need it in an emergency.
Frequently asked questions
Is pet food regulated by FDA?
Yes. FDA regulates pet food as animal food under the Federal Food, Drug, and Cosmetic Act, and states regulate labeling and product registration, often based on AAFCO model rules.
Does FSMA apply to pet food warehouses?
Yes, in part. Warehouses holding animal food are subject to current good manufacturing practices under 21 CFR Part 507, with modified requirements for packaged food that needs temperature control.
Is AAFCO a government agency?
No. AAFCO is an association of state and federal feed officials that publishes model regulations and ingredient definitions that states adopt.
