Michigan Cottage Food Inspection: What MDARD Can and Cannot Do

No Routine Inspections

Michigan cottage food kitchens are exempt from routine pre-opening inspections and periodic health department visits. No inspector comes to your home before you start selling. No one schedules an annual walkthrough. The cottage food exemption under MCL 289.4102 explicitly removes licensed food establishment inspection requirements.

This exemption is one of the law's biggest appeals — it eliminates the overhead and anxiety of a formal inspection process for home-based sellers producing low-risk, shelf-stable foods.

But "exempt from routine inspection" is not the same as "can never be inspected."

MDARD's Complaint Authority

MDARD retains full statutory authority to investigate cottage food operations in response to consumer complaints or suspected foodborne illness. If someone reports getting sick from your product, or alleges that you're selling prohibited foods, operating above the sales cap, or labeling incorrectly, MDARD can:

• Contact you to investigate the complaint
• Enter your residence to inspect production and storage areas
• Examine your products, ingredients, and labeling
• Seize products that violate the Michigan Food Law
• Issue administrative penalties

This complaint-based enforcement model means your operation is only as invisible as your compliance. A single customer complaint — justified or not — triggers the investigation process.

What Triggers Complaints

Most cottage food complaints fall into a few patterns:

Foodborne illness reports. A customer reports symptoms they attribute to your product. MDARD investigates to determine whether the product was non-TCS compliant and whether production conditions could have caused contamination.

Prohibited product sales. Someone reports that you're selling cheesecakes, pickles, dairy products, or other TCS foods under the cottage food exemption. This might come from a competitor, a market manager, or a consumer who understands the rules.

Labeling violations. Missing allergen declarations, no MDARD disclaimer, or products sold without required label elements.

Exceeding the sales cap. Less common, but possible — particularly if your operation is visibly successful and someone questions whether you're still under the applicable sales cap.

Protecting Your Operation

The best defense against a complaint investigation is documentation that proves you operated correctly:

Production logs. Record batch dates, recipes used, quantities produced, and sanitation procedures. If MDARD asks what happened on a specific production day, you have the answer.

Ingredient receipts. Keep purchase records and supplier information for at least three years. If there's an ingredient recall, you can trace which batches were affected.

Sales records. A chronological ledger of every sale demonstrates compliance with the revenue cap and shows that transactions were direct-to-consumer.

Label samples. Keep a copy or photo of your current label. If a complaint alleges missing information, the sample proves what was on the package.

Sanitation records. Document your kitchen cleaning and sanitizing protocols. Even simple notes ("sanitized surfaces with bleach solution before production on 3/15") create a record of good practices.

The Inspection Itself

If MDARD does investigate, the process is complaint-driven, not adversarial. Inspectors look at whether your operation complies with the cottage food exemption — correct products, proper labeling, sanitary conditions, and the applicable sales cap.

If the investigation confirms a violation, MDARD can issue a warning, require corrective action, impose penalties, or seize non-compliant products. The severity depends on the violation.

If the investigation clears you, the complaint closes and no further action is required.

Bottom Line

The lack of routine inspections doesn't mean the absence of accountability. It means accountability is complaint-driven rather than scheduled. Keeping clean records, maintaining sanitary practices, and staying within the exemption's boundaries are the best insurance against a complaint ever becoming a problem.
