## The Problem
Microbial contamination in water systems is a nightmare scenario. Sporadic events can seem manageable, but they can signal deeper systemic issues. The FDA considers certain organisms "objectionable," and failing to respond appropriately can lead to recalls or warning letters.

**Example:** You have sporadic Pseudomonas aeruginosa counts in your water system. Should you be concerned about the non-sterile products you manufacture?

Here's how GKS KeyPedia helps you handle contamination events: Ask KeyPedia to assess the risk based on the specific organism and product type.

**Why?** Because KeyPedia's input is fed from guidance documents, FDA regulations, good practices, FDA-483s, Warning Letters, and a myriad of regulatory sources, structures, and citable frameworks. 

## 1. Ask
Ask KeyPedia: *"I am experiencing microbial contamination on my purified water system. I have sporadic events of Pseudomonas aeruginosa... Do I need to be concerned?"*

## 2. Review
KeyPedia confirms this is an objectionable microorganism and outlines the FDA's strict stance on water system control and product impact. **See the complete KeyPedia response in Dan's LinkedIn post below.**

## 3. Implement
Use the guidance to trigger immediate investigations, sanitation, and impact assessments for released batches.
