The FDA/NCIMS accepted method delivers results in minutes, allowing farmers, milk testing laboratories and dairies to take action to preserve and enhance hygienic quality of the milk supply.
Supported by a dedicated Foss IntegratorTM  software, which provides a wide range of quality assurance and GLP features. Foss Integrator shares the same interface for all CMT instruments.
Superior accuracy through Individual Bacteria Count
BactoScan™  FC+   measures  the  hygienic  quality  of  milk  by analysing bacteria in raw milk. As the automated BactoScan™ FC+ counts the total bacteria as single cells and not clusters, it gives a uniform high accuracy of results. BactoScan™ FC+ can  analyse  raw  milk  from  various  species  and  the  samples can  be  analysed  directly  without  prior  heating  or  dilution. Analysis on cold samples reduce the risk of bacteria growth before the test and save time in sample handling, as well as cost  of  water  bath.  And  unlike  traditional  methods  such  as plate count, BactoScan™ FC+ reduces the possible influence caused  by  the  operator  to  absolute  minimum.  All  ensuring superior performance.
High capacity with confidence
The new BactoScan™ FC+ can analyse up to 200 milk samples per hour to meet the requirements of all milk testing laborato- ries. This high performance capacity enables a high throughput of milk samples, which offloads labour force for other purposes and provides instant results with fast response to farmers.
The repeatability and reproducibility of this automated method is  excellent  compared  to  plate  count  methods.  In  addition, BactoScan™  FC+  employs  a  unique  self-cleaning  program that  is  proven  to  minimize  carry-over  contamination  from previous samples.

The only automated method with U.S. FDA/NCIMS* approval
The BactoScan™ FC+ is the only FDA/NCIMS approved rapid electronic counting method and complies with ISO/IDF guide- lines**.  It  has  become  the  industrial  standard  for  counting total  bacteria  in  many  countries  all  over  the  world,  and  in the  EU  more  than  75%  of  all  milk  supplies  are  paid  based on BactoScan™ results. Dairy authorities have seen a signifi- cant improvement in milk quality shortly after introducing the BactoScan™ method.

Traditional plate count method versus BactoScan™ FC+ farmer and dairy benefits
Although  pasteurisation  kills  the  majority  of  bacteria, their metabolites may cause off flavours. Plus, enzymes continue their activities resulting in product defects and reduction of shelf life. Catching hygiene breaches early is imperative for minimizing the impact on milk quality.
Because  the  traditional  plate  count  method  requires two-three  days  of  incubation,  hygienic  problems  on the farm may go undetected for days, making correc- tive actions more difficult and production losses larger than necessary.
In comparison, the BactoScan™ FC+ method delivers a result in nine minutes. Farmers can be advised about possible problems the same day as the sample is drawn allowing timely correction for leaks, insufficient cleaning or cooling in the milking system, or health problems in the herd.
Further,  monitoring  the  incoming  raw  milk  at  dairies means that serious contamination can be detected in- stantly. Poor quality milk can be rejected and only the best suited milk will be used for dairy production. The fast BactoScan™ FC+ response to farmers gives dairies a direct economic benefit by enabling higher flexibility in collection, transportation and production.
BactoScan™ FC+ is based on flow cytometry technology that enables precise and instant milk bacteria analyses.
Flow cytometry is a technique that counts bacteria cells. The principle behind flow cytometry is quite simple: a suspension of cells is stained and forced through a capilary tube, which is illuminated in front of microscope objective. Every passing cell is registered by photo electronics attached to the microscope.
Prior to measurement all components in the milk, except for the bacteria, are broken down during an incubation period. Additionally,  the  bacteria  clusters  are  separated  into  single bacteria, which are subsequently dyed with DNA specific stain- ing medium, ethidium bromide. All the reagents involved are automatically filtered directly prior the application to eliminate the risk of contamination from other sources than the milk.
Even the uncompensated carry-over is extremely low for the BactoScan™  FC+  and  proven  to  be  below  0.5%,  which  is superior to the 1% required by the ISO/IDF. A carry-over test is a part of the quality assurance and checks that the instru- ment is able to purge a sample completely through the system without affecting the next sample. The test complies with the ISO/IDF standard.
IBC to CFU conversion
BactoScan™  FC+  measures  Individual  Bacteria  Count  and displays results in IBC. However, many laboratories are obliged to present their results in Colony Forming Units (CFU), which can  be  obtained  by  a  plate  count  method.  Consequently,  a conversion table has to be created to convert from IBC to CFU.
The BactoScan™ FC+ software includes a Guided Conversion Tool  –  an  easy  and  rapid  software  tool  to  develop  a  robust conversion table between IBC and CFU
Respect to ISO 21187: 2004 (IDF196: 2004)
Automatic calculation of agreement (Sy,x) with CFU
Easy trouble shooting and outliers traceability
Excellent storage for data generated over time
Simple and time effective use
Enables to meet the governmental and legislative require- ments
Enables use of  comparable  grading  limits  for  payment
A precise syringe is used to pass the sample through a flow cell, presenting the bacteria one by one to a fluorescent light beam from a laser source. The stained bacteria emit red light with one light pulse for every bacteria passing the beam.
The fluorescent light is detected by a highly sensitive detector (Photo Multiplier Tube – PMT), which gives electronic impulses. The  electronics  count  the  pulses  and  display  them  in  a  puls height analysis (PHA) diagram on the PC monitor.
Avoiding carry-over
FOSS has developed a unique self-cleaning program to limit carry-over contamination from previous samples. Optionally, the effect of carry-over between the samples may be reduced by  a  mathematical  compensation  that  is  made  automatical- ly.  Such  compensation  is  based  on  observed  carry-over  be- tween  the  samples  and  can  be  deducted  from  the  results.
“BactoScan™ FC+ carry-over below 0.5%which is superior to 1% required by the ISO/IDF”
Special feature for difficult milk samples
Options are available to handle milk samples from, for example, sheep and goat which can be subject to high concentrations of somatic cells – like in goats milk at the end of lactation. This induces  background  noise  leading  to  high  readings  on  the BactoScan™ FC+ – often due to increased viscosity of the milk sample, which in turn will make the flow of the sample film through the flow cell unstable. The influence of the background noise typically starts > 4 mill. somatic cells/ml.
The  Enhanced  mode  option  stabilizes  the  flow  of  the  film through  the  flow  cell.  The  measuring  speed  of  milk  will  be reduced  by  either  50%  with  the  mode  1,  or  75%  with  the mode 2 without affecting the speed capacity of the instrument.
Foss Integrator software platform
Foss Integrator is a shared software platform supporting other FOSS milk testing solutions. The same user interface, the same conveyors, bar code readers etc. can be used throughout the laboratory. This eases training of laboratory staff and facilitates data handling, transfer and storage. Uniform software provides flexibility in the laboratory.
Further,  context  sensitive  help  available  via  Foss  Integrator software  provides  easy  and  quick  solutions  and  answers,  as well as provides an excellent tool for quality assurance.
Quality control tools
Together with the BactoScan™ FC+ you get a number of tools which provide excellent help in recording quality assurance and following the Good Laboratory Practice:
The  Bacteria  Control  Sample  (BCS)  ensures  the  correct  per- formance  of  the  instrument  and  reagents  throughout  the working day and standardises instruments within and between laboratories.  The  BCS  is  made  of  freeze  dried  monoculture harmless bacteria with a known count and specific Pulse Height Analysis (PHA) curve.
The Particle Control Sample (PCS) enables monitoring of the technical status of the instrument. It is necessary when adjusting the optical system and is mainly a service tool for maintenance and repair. It is made of dyed fluorescent particles with a well defined PHA curve
A Frozen Milk Standard is used to monitor the accuracy and stability of the instrument. The frozen milk standard is made of good quality raw milk with a known bacteria count. When applied on regular basis, the milk standard plays a crucial role in quality assurance.
