Bacteria, viruses and toxins detection in food or beverage

Hello Everyone,

I am looking for NDT technologies that could be used to rapidly detect and identify pathogen bacteria, viruses and toxins in food or beverage products (i.e. Salmonella, E. coli, Yersinia enterocolitica, Shigella, Cyclospora, Cryptosporidium,...).

I am aware of «polymerase chain reaction» methods (PCR) but not interested by these techniques. Preferably, the apparatus or technologies I am looking for must be portable and in-situ. In all cases, they must be capable of detecting within a maximum of 24 hours but preferably in minutes and allow to distinguish between the harmless bacteria and the ones that represent a threat to consumer’s health.

Thanks in advance for any info anyone may provide.
Best Regards
Vincent

Vincent...try a portable blacklight. Some cultures fluoresce. A local dairy used this as an aid to periodic cleaning of components.

As a former wastewater treatment operator, I would suggest you look at some of the methods that wastewater treatment plants use to detect those same types of pathogens.

SITEX CPSERIES

Teledyne ICM’s CPSERIES has been designed with a view to revolutionizing the handling and perfor
...
mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).

TOPAZ® 64: Fully Integrated Portable 32 or 64 Channel PAUT Instrument with FMC & TFM

Introducing TOPAZ64, the industry’s most intelligent fully integrated, portable 32 or 64-channel
...
phased array ultrasound (UT) instrument. TOPAZ64 combines code-compliant phased array UT with the industry’s most advanced full matrix capture (FMC) and total focusing method (TFM) capabilities. Featuring the highest acquisition frequency in its class, high resolution FMC and a 12” multi-touchscreen, users can easily visualize even the smallest flaws. TOPAZ64 can generate a bipolar pulse that provides more acoustic energy versus previous models for punching through thick components. The result is a portable tool that delivers increased inspection coverage, more accurate signals, and the ability to handle all UT inspections in one package. TOPAZ64 is ideal for challenging applications in transportation, oil and gas, manufacturing and power generation.
