In the complex world of environmental monitoring, selecting the right supplier of prepared media for your business demands careful consideration. In this first, of a two-part series of posts, I'll guide you through evaluating the supplier, the second post will address the validation consideration. 

Compliance with Quality and Regulatory Standards

Selecting a new supplier of prepared media is a significant decision that requires  thorough evaluation prior to embarking upon the lengthy and costly validation process.

Effective evaluation is crucial to ensure  the chosen supplier can meet quality, regulatory, and operational needs before the more resource-intensive step of validation commences.

One of the first steps in evaluating a potential new supplier is verifying products meet the relevant quality and regulatory standards. 


Alignment with GMP Standards 

For industries adhering to Good Manufacturing Practice (GMP), such as  pharmaceuticals, it's vital to confirm the supplier's media complies with pharmacopeia standards. For example, the supplier’s formulation and performance, including productivity ratio (PR) of the media must align to the required benchmarks in order to ensure compliance.

In sectors like  food and water testing, confirming compliance with international standards is equally important . 

Regardless of the industry in which you operate, always request and review the supplier's certificate of analysis (CoA) during the evaluation. The CoA should provide details of the organisms used for testing, their culture collection reference numbers, and  the reporting methodologies. 

Configuration and Adaptability

In addition to regulatory compliance, it’s crucial to determine that the configuration of the product aligns to your operational requirements. For example, if your processes require bottled media in snap-cap, but the supplier is limited to providing bottles with screw caps, a switch is likely to be impractical.

Evaluating the supplier’s adaptability to accommodate future needs as your business expands and evolves is essential. Review their strategies in relation to flexibility, compatibility and scalability.  

New Call-to-action

On-Site Audits and Facility Inspections

While reviewing documentation is a necessary part of evaluation, on-site auditing will provide valuable insights into a supplier's operations.

An audit allows you to assess the operational facilities such as raw material management and cleanroom conditions, which is essential for maintaining contamination control. 

Assess cleanroom classification along with environmental monitoring protocols to ensure alignment to your contamination control strategy.

Evaluate the quality control (QC) testing regime  to ensure homogeneity and stability of the products is proven. For instance, Cherwell, test samples from the start, middle, and end of batches  to ensure uniform quality providing assurance of homogeneity and stability across the batch.

Communication and Issue Management

A supplier’s ability to address and efficiently resolve issues is a vital factor. During evaluation, take time to examine their complaint management process. For example, if a batch of media fails close to a project deadline, how quickly can they react and rectify the problem? 

Maintaining secondary suppliers can be useful as part of risk mitigation or business continuity strategy. These might be companies unable to manage large batch orders, but their agility can be invaluable for urgent needs when the primary supplier is unable to do so.

Long-Term Relationships

Evaluating a new supplier is a multi-faceted process involving more than just checking compliance. It requires examination of the supplier’s adaptability, quality control measures, and ability to respond to issues quickly. 

It’s also important to think long-term. Is the supplier you're considering adaptable enough to grow with your business? Can they accommodate new configurations as your operations evolve?

Asking these questions during the evaluation process will help determine whether the supplier can support the long term needs of your business.  

Only after a potential supplier has successfully passed the evaluation stage should you proceed with the validation phase.
