Meat and poultry
Lot release and line monitoring where Salmonella is the criterion holding the product. The result arrives on the same production day.

RNA detection · Salmonella and Listeria
Salmonella and Listeria spp., settled the same day.
RNA detection from viable cells in our laboratory: Salmonella on surfaces and environments in 6 to 8 hours, finished product from 12 hours, with ISO 17025 accredited methodologies.

The method
We measure RNA, not the trace of what is already dead.
DNA-based PCR also amplifies material from dead cells — hence the positives that later fail to confirm. AiGOR amplifies RNA from viable cells, so what gets reported is what is still alive in the sample.
Salmonella spp.
RNA from viable cells6–8 h
Surfaces, environments, raw materials and finished product. AiGOR detects Salmonella spp. at much lower loads than standard DNA-based PCR, from a single reaction.
Listeria spp. · L. monocytogenes
RNA from viable cellsFrom 8 h
The same workflow for Listeria environmental monitoring: contact points, drains, equipment and ready-to-eat zones, with species confirmation when the plan calls for it.
Traditional culture
- Enrichment sets the pace: there is no useful read until the culture grows, and that is product held in the warehouse.
- DNA-based PCR does not tell live cells from dead ones, and residual DNA triggers positives the lab ends up retesting.
- Every retest adds days and cost to a lot that was already ready to ship.
RNA detection at TAAG
- Salmonella on surfaces and environments in 6–8 h; finished product from 12 h.
- Viable cells only: it avoids the false positives that dead-cell DNA signals cause.
- ISO 17025 accredited methodologies and a certificate of analysis in TxA, at no extra cost.
Where it changes the decision
One assay, four different decisions
02
Ready-to-eat and dairy
Exposed-product zones, where the Listeria plan drives the rest of the sampling: drains, contact surfaces and equipment, at the frequency the plan requires.

03
Food and beverage
Confectionery, egg products, fresh and processed produce, pet food: matrices where a late positive means product already shipped.

Environments, surfaces and water
Microbiological surveys and hot-spot mapping: where the organism keeps coming back and how often, so the next sampling round can be prioritised.

Certificates and trends in TxA, in real time
Only what is alive
Targeting RNA from viable cells avoids the dead-cell signals that cause false positives in DNA-based assays, cutting unnecessary lab retests.
ISO 17025 accreditation
All our methodologies are accredited, across the four sites: Chicago, Mexico City, Santiago and Brussels.
TxA platform included
Trends and certificates of analysis in real time, at no extra cost: ask it about a line's risk in plain language.
Quoting and logistics
Quoted by assay and by volume
A 20-minute meeting is enough to define matrices, sampling points and frequency. The combination of assays and the quote follow from there.
01
We define matrix and points
What gets tested — surface, environment, raw material or finished product — and how often.
02
We sample, or your team does
We can sample at your plant or hand you the devices so your people do it. Sample pickup from every site.

Frequently asked questions
Before you send the sample
How long do results take?
Salmonella on surfaces and environments, 6 to 8 hours; Listeria spp., from 8 hours. On finished product, from 12 hours. The multiplex panel (L. monocytogenes, S. aureus, E. coli and Salmonella) takes 1–2 days.
Do you sample, or do I?
Both options: we can sample directly at your plant or hand you the devices so your team takes the samples.
Are you accredited?
Yes, all our methodologies are accredited under ISO 17025.
Why RNA and not DNA?
DNA from dead cells still amplifies and produces positives that later fail to confirm. RNA is only present in viable cells, so the result reflects the lot's real risk.
Which countries have a laboratory?
Chicago (USA), Mexico City, Santiago (Chile) and Brussels (Belgium), each with sample pickup coverage in its region.
What if I need to know the species?
Species-level identification is done by sequencing, in 5 to 10 days: that is the NGS identification service, which runs in the same laboratory.
