Paul Industries is a nationwide process-equipment and sanitary-piping contractor working across Missouri: cleanrooms, high-purity water, sanitary process piping, CIP/SIP and process equipment installation. Missouri sits at the center of the animal health corridor running through the Kansas City region, and animal health is the one sector where most contractors get the regulator wrong. Animal drugs and animal vaccines are overseen by two different federal agencies under two different statutes, and that determines what you have to build.

Missouri boiler and pressure vessel registration
Alongside the animal-health regulatory split above, Missouri applies its own requirements to the pressure equipment a process plant contains. The Missouri Division of Fire Safety’s boiler and pressure vessel program requires that boilers, hot water heaters and pressure vessels are constructed to the ASME Boiler and Pressure Vessel Code and registered with the National Board of Boiler and Pressure Vessel Inspectors.
That has a direct consequence for procurement. A vessel bought on price from a fabricator without an ASME stamp, or without the manufacturer’s data report filed with the National Board, can arrive on site and be unusable. It is one of the few project failures that cannot be engineered around after delivery, because the deficiency is in the vessel’s documentation rather than in its construction.
We check three things before a vessel is ordered: that the fabricator holds the appropriate ASME certification, that National Board registration will be filed and the data report supplied, and that the installed arrangement leaves the nameplate readable and the vessel accessible for the inspections that follow.
Two products, two agencies, one building
This is the point worth getting right before anything is designed. A pharmaceutical product intended for animals is regulated by FDA through its Center for Veterinary Medicine, and manufacturing follows cGMP under 21 CFR 211 much as a human drug would. A veterinary biologic, meaning a vaccine, bacterin, antiserum or similar, is regulated by USDA through APHIS under the Virus-Serum-Toxin Act rather than by FDA at all.
The practical consequences are real. The inspecting agency is different, the licensing pathway is different, and the expectations around facility design, containment of live organisms and documentation come from a different rulebook. A contractor who assumes FDA cGMP applies to everything in an animal health facility will build to the wrong standard in one half of it, and a facility that makes both, which many do, has to satisfy both simultaneously in shared systems.
Live organism handling is where the difference bites hardest. Vaccine production involves growing and then inactivating or attenuating organisms, which brings biosafety containment, decontamination of effluent before discharge and segregation between live and inactivated areas. Those requirements do not come from 21 CFR 211 and are not satisfied by meeting it.
What that means for the process systems
| Element | Animal drugs (FDA CVM) | Veterinary biologics (USDA APHIS) |
|---|---|---|
| Governing framework | cGMP under 21 CFR 211 | Virus-Serum-Toxin Act, USDA licensing |
| Inspecting agency | FDA | USDA APHIS |
| Live organisms | Generally not | Central to the process |
| Effluent | Conventional process waste | Inactivation before discharge, verified |
| Containment | Product protection | Product protection and biological containment |
| Water | USP Purified Water or WFI by product | Purified Water, with WFI where the product requires |
What we build for Missouri facilities
- Cleanrooms and containment suites ISO 14644 classified environments, including the segregation between live and inactivated areas that biologics production requires.
- High-purity water systems Purified Water and WFI generation, storage and distribution to USP 643 and USP 645.
- CIP and SIP systems Including sterilization of fermentation and downstream equipment with cycle verification.
- Effluent inactivation Kill systems for viable biological waste, with verified cycles and no bypass.
- Sanitary process piping Orbital-welded stainless with weld logs, borescope records and material traceability.
When one building serves two agencies, the finish record matters twice over, which is why passivation with per-line documentation is written into the scope rather than left to the fabricator.
Why Paul Industries in Missouri
Because a facility that makes both drugs and biologics has to satisfy two agencies in shared systems, and shared systems are where multi-vendor projects lose accountability. Holding the cleanroom, water, piping and effluent scopes under one contract means one party can answer whether the arrangement works for both rulebooks rather than each vendor answering for its own piece.

Frequently asked questions
Who regulates animal vaccine manufacturing?
USDA, through its Animal and Plant Health Inspection Service, under the Virus-Serum-Toxin Act. Not FDA. This surprises people regularly, including contractors, because the facility looks like a pharmaceutical plant and the assumption is that FDA cGMP governs it. Veterinary biologics have their own licensing pathway and their own inspection regime, and designing to 21 CFR 211 alone will not satisfy it.
Who regulates animal drugs then?
FDA, through the Center for Veterinary Medicine. Manufacturing follows cGMP under 21 CFR 211 much as a human drug would, with the same expectations around batch records, validated cleaning, qualified equipment and compendial water where the product requires it. So a company making both drugs and vaccines is answering to two agencies under two statutes, frequently in the same building.
What changes when live organisms are involved?
Containment becomes a design driver alongside product protection. That means biosafety-appropriate separation between live and inactivated areas, controlled airflow and pressure regimes, decontamination routes for equipment and waste, and effluent that is inactivated before it reaches drain. None of this comes from 21 CFR 211, and a facility built only to that standard will need retrofitting to handle biologics properly.
What is a kill system and when is it required?
A kill or inactivation system treats viable biological waste, using heat or chemical treatment with a verified cycle, before it can be discharged. It is normally required wherever the process handles live organisms, driven by biosafety containment level and permit conditions. The engineering points that matter are cycle verification, capacity against peak batch volume, and ensuring no bypass route exists around it.
Can drug and biologic production share utilities?
Some can, some should not, and the decision needs making explicitly. Shared purified water is common and manageable. Shared air handling between live-organism areas and drug production is usually not acceptable. Shared drainage between a biologics area and conventional process waste defeats the inactivation requirement entirely. The rule of thumb is that anything capable of carrying an organism should not be shared.
Does animal health production need WFI?
It depends on the product and its route of administration rather than on the species. An injectable product generally needs Water for Injection meeting USP 643, USP 645 and 0.25 EU per milliliter endotoxin, whether the patient is human or animal. Oral and topical products typically need Purified Water. Specifying WFI across a whole site because part of it is injectable is a common and expensive default.
How is SIP used in vaccine production?
Heavily, because fermentation and downstream equipment has to be sterilized between batches to prevent contamination of the culture and to inactivate what was in it. Cycle verification by thermocouple mapping matters particularly here, placed at the points hardest to heat: low points collecting condensate, dead legs, valve bodies and any element with a heat sink. Condensate removal and air venting usually determine whether the cycle works.
Do you work with Missouri food and brewing operations?
Yes. Food and brewing work follows food-contact sanitary design rather than cGMP, with tanks, transfer, heat exchange and CIP as the core scopes and a considerably lighter documentation burden. Missouri has a substantial base of both, and the useful discipline when working across sectors is scoping each to the standard that actually applies rather than carrying assumptions between them.
Does Missouri energy cost affect design?
Barely. Industrial electricity averaged 7.87 cents per kilowatt-hour in 2024 against a national average of 8.13 (EIA), just below the midpoint. That means design decisions can follow the process and regulatory requirement rather than being pulled by energy economics, unlike California where efficiency dominates the calculation or the Gulf Coast where it barely registers.
How do I get a quote for a Missouri project?
Use the form on this page or call 201-450-8280. The most useful first answer is which products you make and therefore which agency licenses them, because that determines almost everything downstream. Beyond that: whether live organisms are handled, your water requirement by product, what utilities are shared today, and whether the facility is new build or expansion.
Who regulates veterinary biologics in the United States?
The USDA Center for Veterinary Biologics licenses and regulates veterinary vaccines and related biologics, under a separate framework from human pharmaceuticals. Facility and process expectations differ in detail from FDA drug cGMP.
Who regulates animal drugs as opposed to biologics?
The FDA Center for Veterinary Medicine regulates animal drugs, which fall under drug cGMP expectations. A site making both a vaccine and a drug therefore answers to two agencies with two frameworks inside one building.
What changes in facility design when live organisms are handled?
Containment becomes a requirement alongside sterility, effluent containing viable material has to be inactivated, and the building has to support decontamination. Pressure regimes and drainage change, and both are difficult to retrofit.
How is decontamination handled between vaccine campaigns?
Through a validated cleaning and decontamination procedure demonstrated effective against the specific organism, with verification sampling before the next product. Where effectiveness cannot be demonstrated, dedicated equipment replaces the changeover.
What is a master seed and how does facility design protect it?
The characterised stock from which production batches derive, held under controlled storage with redundancy and monitoring because its loss is unrecoverable. Storage redundancy and alarm response are facility decisions with existential consequences.
Does animal health production require Water for Injection?
Parenteral veterinary products carry water quality requirements comparable in principle to human parenterals, so Water for Injection is commonly required for those. Oral and topical products frequently do not, which is a large cost difference.
How is sterilisation in place used in vaccine production?
To sterilise fermenters, transfer lines and filter housings between batches so the sterile boundary holds through the run. Cycle development and thermocouple mapping are the same discipline as in human biologics manufacturing.
What does Missouri boiler and pressure vessel registration require?
Registration and periodic inspection under the state programme, with intervals depending on the equipment and service. It is an administrative and scheduling matter rather than a design constraint.
Can one contractor work across both regulatory frameworks on one site?
Yes, and it is an advantage, because the difficult part is the boundary between the areas and the shared utilities crossing it. A contractor who understands both frameworks can design the separation rather than discovering it during qualification.
What do Missouri food and brewing operations need from process systems?
Sanitary stainless piping, CIP, heat exchange and tank systems built for food safety rather than cGMP, with the documentation scaled accordingly. The construction quality is comparable. The paperwork burden is not.
How is cross-contamination controlled between vaccine strains?
Through campaign separation with validated cleaning and decontamination between products, or through dedicated equipment where the risk assessment requires it. Live organism carryover is not a residue problem in the ordinary sense, which changes how cleaning is validated.
What air handling does a veterinary biologics suite need?
Single-pass air where recirculation would carry organisms, a cascade designed for containment rather than only for product protection, and exhaust filtration appropriate to the organism handled. It is closer to a containment facility than to a standard cleanroom.
Does the animal health sector use the same validation approach?
The lifecycle thinking is the same, with qualification of equipment and validation of processes, and the specific expectations and the reviewing agency differ. A team experienced in human pharmaceutical validation adapts rather than starts over.
What is different about a site making both human and animal products?
Segregation becomes the central design problem, because cross-contamination between the two is not acceptable in either direction. That usually means separate suites and separate air handling rather than scheduling.
How should a Missouri project handle two agencies in one building?
By defining the boundary physically, documenting which framework applies where, and building the evidence set each agency expects for its own area. Attempting a single blended standard satisfies neither reviewer.
