- Microorganism Identification & Contamination Tracking
Strain-level microbial analysis for root-cause investigations, traceability, and contamination control in food & biopharma production
Microbial Identification & tracking
Our Microbial Identification & Track Service uses Whole Genome Sequencing (WGS) to determine the genetic similarity between isolates from finished product positives, environmental findings, and raw materials. This enables manufacturers to confirm whether contamination originated within the factory environment or was introduced externally e.g through a raw material, supplier, or external laboratory.
Our WGS approach delivers strain-level resolution, providing definitive microbial fingerprinting to support root-cause investigations, CAPA implementation, and regulatory compliance. By analysing the entire DNA sequence of each isolate, we can detect even subtle genetic differences and establish whether isolates are genetically identical, closely related, or unrelated.
culture-free sequencing & Identification
Our culture-free, sequence-based service identifies microorganisms from multiple different sample types. This advanced microbial identification service empowers businesses to mitigate risks, and ensure the safety of consumers.
No matter what the sample type, our cutting-edge identification techniques can proactively address your microorganism challenges by not only identifying the species of concern but delving deeper to give you precise information on biocide resistance, the presence of toxin genes, and the context of the sample.
Frequently Asked Questions (FAQs) About or Microbial Identification & Tracking Service
What is ELDA’s Microbial Identification & Tracking service?
ELDA Microbial Identification & Tracking uses Whole Genome Sequencing (WGS) to deliver strain-level resolution for bacterial/fungal contaminants. WGS compares full isolate genomes to confirm whether a positive finding is a recurring strain in your environment or a new introduction (e.g., supplier, raw material, external lab).
What methods do you use?
We use Whole Genome Sequencing (WGS) for definitive isolate identification and strain relatedness. When broad microbial community profiling is needed such as complex, mixed, or culture-negative samples we offer metagenomic testing (see below for details)
What sample types can be tested?
We accept bacterial and fungal isolates from a wide range of sources, including environmental monitoring samples such as air, water, and surfaces, as well as raw materials, finished products, utilities, and packaging environments.
How can I send a sample?
Contact our scientific team at info@eldabiotech.com or use the online Sample Submission Form to receive a quote and packaging guide
What are the standard turnaround times?
Turnaround times depend on the testing method. Results are typically available within 3-5 working days from sample receipt. Expedited analysis can be arranged upon request to meet urgent investigation needs.
What does the report include?
Our standard reports include species identification, MLST/sequence type (ST), and allele profile. When requested, we can also perform core-genome SNP (cgSNP) analysis to assess strain relatedness. If enabled, results are compared against your historical isolates to determine whether a finding represents a recurring strain or the introduction of a new, unrelated contaminant. When requested we maintain a confidential client isolate database to monitor trends by line, area, site, or season, supporting effective CAPA and contamination prevention programs.
Do you provide interpretation support?
Yes, our scientific team are available to discuss any queries from sample submission, sample types to reporting results.
Are results kept confidential?
Yes. All client data, sequences, and reports are stored securely. We never share client information or results without prior written consent.
How does ELDA Biotech fit into my current workflow?
We complement your existing microbiological testing process. Routine culture and detection can continue with your in-house or contract testing lab, once a contaminant is isolated or flagged, it can be sent directly to ELDA for Whole Genome Sequencing (WGS). We integrate seamlessly as your specialist sequencing partner, providing strain-level identification and relatedness data that feed back into your root-cause investigations, CAPA, and environmental monitoring programs. Results can be shared with your QA or technical team in standardised report formats or personalised for easy documentation, trending, and audit readiness.
