Operating from a sprawling 12,000-square-foot facility in Riverdale, New Jersey, PDA Laboratories is a premier third-party partner for microbiology and analytical sample testing across North America. What began in 2011 as a humble 2,500-square-foot operation has become an indispensable resource to cosmetics, nutraceuticals, and pharmaceutical manufacturers navigating complex product formulations and evolving regulatory landscapes.
Every phase of PDA’s journey radiates its founder’s commitment to meeting scientific standards and delivering the market-responsive agility that modern manufacturers demand. Its reputation is not the result of marketing slogans, but of years spent troubleshooting real-world production challenges, turning laboratory analysis into a critical instrument for decision-making where public safety and brand integrity intersect.
Its reputation is hard-earned. Manufacturers and packagers depend on PDA not just to release compliant batches, but to avert costly errors, recalls, and the risk of consumer harm.
“We make sure that formulas are safe, the products are clean, and that there are no pathogens that could harm the end client or ruin the product,” says James Seijas, VP Operations, substantiating its position in the market.
This ethos is reiterated in every technical protocol. The laboratory’s microbiology services include USP <60>, <61> and <62> plate counts, yeast and mold enumeration, and targeted pathogen detection. PDA also specializes in preservative effectiveness testing PCPC (PET) and antimicrobial effectiveness testing USP <51> (AET), which are critical for ensuring product safety.
Beyond routine analysis, it conducts microbial identifications and comprehensive facility assessments, supporting clients with environmental air and surface sampling, aseptic validation on production lines, and raw material evaluations to prevent contamination before it compromises product quality. Stability study programs are also offered, customizing accelerated and real-time conditions with microbiology and analytical testing at designated intervals. Formal OOS (out of specification reports) are available upon request as well.
PDA Laboratories’ analytical division provides advanced solutions like viscosity, assays, organoleptic attributes, pH levels, high-performance liquid chromatography (HPLC), gas chromatography (GC), and specialized testing for regulated impurities such as benzene, and 1,4-dioxane. The analytical lab also specializes in sunscreen actives testing. Recent capital investments have enabled in-house ICP-MS to quantify heavy metals and total organic carbon (TOC) for water analysis, transitioning services once outsourced to rapid, internal processes with stronger data integrity. Method verifications and validations ensure every report is defensible and compliant.

Problem-Solving Beyond the Benchtop
PDA emphasizes being more than a passive testing provider. The team’s distinction lies in expert consultation and hands-on client support during critical incidents. When a manufacturer faced unresolved micro contamination, PDA’s team went onsite, conducted thorough environmental monitoring, including an assessment of water system integrity, and implemented adequate sanitation and sampling protocols.
This intervention enabled operational recovery and protected the client’s brand reputation.
These services produce more than numbers; they help clients avoid recalls and unsafe product releases, providing essential assurance that has fueled PDA’s growth through positive referrals. PDA ensures that every production line employs proper aseptic techniques, minimizing the risk of contamination and regulatory setback. The company’s responsive reporting—providing preliminary microbiology results within three days and final reports in five to seven days—supports transparency and enables rapid decision-making. The robust Quality Assurance department oversees and electronically transmits reports with extremely low revision rates. This has led to impressive client loyalty, consistent reputation growth, and a thriving referral network for PDA.
Accredited Excellence and Forward Momentum
Regulatory rigor shapes every aspect of PDA’s operation. With ISO 17025 accreditation, FDA registration, Health Canada approval, and a DEA license for controlled substances, PDA’s credentials establish it as a reliable partner for manufacturers whose success depends on accuracy and compliance. Now averaging 20 percent annual growth, PDA is focused on expanding its outreach, visibility, and service capacity.
“We are at a point where we can handle significantly more sample volume,” states Seijas, positioning the facility as ready for increasing market demand without compromising quality.
As oversight tightens and innovation accelerates, PDA remains dedicated to advancing industry standards. Its combination of advanced scientific expertise, regulatory commitment, and hands-on support ensures safe, compliant products for consumers and a more reliable, resilient marketplace for manufacturers.
Selecting Microbiology Testing Services for Regulated Product Release
Microbiology testing plays a critical role in product release for biotechnology, pharmaceutical, nutraceutical and personal care manufacturers. Product safety is no longer assessed only at the finished-goods stage. It relies on disciplined sampling of raw materials, water systems, production environments and finished products. For executives evaluating a testing partner, the central question is whether the laboratory can help reduce release risk while enabling quality teams to identify the source of contamination when results fall outside expected limits.
A strong testing partner combines compendial expertise with practical problem-solving. Routine plate counts, microbial limits testing, pathogen detection, preservative effectiveness testing and sterility-related services support decisions directly tied to batch release, shelf stability and consumer safety. Yet testing alone is not enough. Laboratories should also help interpret findings, identify recurring trends and determine whether issues stem from formulation, water systems, handling practices, packaging or the production environment.
Breadth adds value when it leads to better decisions. Manufacturers benefit when microbiology testing is integrated with environmental monitoring, water testing and related analytical services because contamination issues rarely stay confined to one area. Alert and action limits, air and surface sampling, compressed gas testing, microbial identification and facility reviews help quality teams move more quickly from failed results to corrective action. This is particularly important for companies managing multiple product lines, contract manufacturing partnerships or release schedules tied to retail, clinical or distribution commitments.
Accreditation and inspection history should also factor heavily into the evaluation process. A laboratory's technical capabilities matter only if its quality system can stand up to scrutiny from customers, auditors and regulators. Manufacturers should look for demonstrated competence, recognized approvals, transparent reporting practices and the ability to support investigations without adding unnecessary complexity. Turnaround time is also a quality consideration. Preliminary reporting, timely final reports and direct communication help internal teams decide whether to hold, release, rework or further investigate a product.
The strongest laboratory relationships are built on integration with a manufacturer's broader quality-control process rather than simple sample processing. That includes routine testing, method support, response to unexpected findings and access to experienced personnel when issues extend beyond the submitted sample. A dependable testing partner gives executives confidence that scientific judgment, testing capacity and regulatory readiness are working together. It also helps quality leaders protect release schedules without compromising scientific rigor for speed.
PDA is a strong choice for organizations seeking microbiology testing backed by practical investigative support. The company provides microbial content testing aligned with USP standards, preservative and antimicrobial effectiveness testing, microbial identification, pathogen detection, sterility-related services, bioburden testing, environmental monitoring and water-system testing. Its Riverdale, New Jersey, facility brings together microbiology and chemistry capabilities, including onsite laboratory space and expanded analytical services that help address related release questions. PDA also maintains ISO 17025 certification, Health Canada approval, FDA registration and a DEA license. Preliminary microbiology reports, environmental protocols and facility troubleshooting capabilities make the company especially valuable when manufacturers need timely insight before issues escalate into missed shipments or unnecessary product holds.
