Infant formula CGMP: nothing leaves quarantine until it meets every specification
Part 106 is strict by design: every production aggregate stays in quarantine until it meets every specification, and its code traces every stage.
In Short
- Powdered formula: Cronobacter and Salmonella, none detected.
- Quarantine until all specifications are met.
- One sequential code traces every stage of manufacture.

The Infant Formula Manufacturing Guide
Every nutrient checked. Every can traceable.
21 CFR Part 106 is FDA's binding CGMP and quality control rule for infant formula. It sits on top of the general food CGMP rules and the infant formula requirements in section 412 of the FD&C Act. This guide covers the sections production and quality teams ask about most. Every section cited was checked on the eCFR on 2 Oct 2026.
Production and in-Process Control
106.6 requires a production and in-process control system covering every stage, with specifications at points where control is needed, and the manufacturer reviews and evaluates the results. Separately, 106.50 has an individual qualified by education, training, or experience review deviations from the master manufacturing order and document the outcome.
Microbiological Testing
106.55 requires controls to prevent contamination by microorganisms. For powdered formula, each production aggregate is tested for Cronobacter spp.

| Organism | Samples | Sample size | Limit |
|---|---|---|---|

(30 samples of 10 g) and Salmonella spp. (60 samples of 25 g), with none detected.
Quarantine until release
106.70 requires each production aggregate to be held under a quarantine system until it meets all of the manufacturer's specifications, or until a documented review finds that a failure does not result in, and could not lead to, adulteration. Product that fails is quarantined until a qualified individual decides.
Can this aggregate leave quarantine?
- Who released and against which results is recorded.
Coding and Traceability
106.80 requires each production aggregate to be coded with a sequential number that identifies the product and establishment and lets you trace all stages of manufacture, including the packing period and the receipt and handling of raw materials.
Audits and Records
106.90 to 106.94 require regular audits of CGMP and quality control procedures. 106.100 lists the records, including test results, calibration and deviation reviews.

V5 records batch steps, lab results, holds and lot trace. Qualified people decide release.
Questions
Which microorganisms must powdered infant formula be tested for?
Under 106.55, each production aggregate of powdered formula is tested for Cronobacter spp. (30 samples of 10 g) and Salmonella spp. (60 samples of 25 g), with none detected.
When can a production aggregate be released?
Under 106.70, only when it meets all of the manufacturer's specifications, or when a documented review finds that a failure does not result in and could not lead to adulteration.
What must the production code show?
Under 106.80, a sequential number identifying the product and establishment that lets you trace all stages of manufacture, including the packing period and raw material receipt and handling.
Does V5 release infant formula?
No. V5 records batch steps, laboratory results, holds and lot trace with electronic signatures. An authorised qualified individual makes and documents disposition and release; V5 only records the evidence.
