1. Bovine individual traceability |
Nowadays, the risk of BSE requires the animal to be
traceable from the birth to the consumer. Even if the
animal is traced between birth and carcass, it remains difficult to guarantee the origin of a steak.
It is also important to verify that meat in the storehouse corresponds to the carcass at the slaughter-house.
We can offer you :
|
-
The comparison between the meats and the origin carcass by their DNA.
-
An individual genetic identification on meats and carcasses and the profile comparison.
-
A comparative system with a probability over 99% to say the individuals are identical.

2. Olive variety determination |
|
DNA is the molecule which carries the genetic code. It is now possible to recognise the olive-tree varieties using a technique developed in the Montpellier site of the INRA, based on the microsatellites markers.
This technique can already be used to certify your trees, and also to authenticate the main variety of olive present in an “extra virgin” olive oil.
The microsatellite markers are repetitive sequences of the genetic code, the length depends on the variety. Those markers are present in many parts of the DNA chain; it needs 10 microsatellite markers to differentiate and identify every olive-tree
variety.
Our company has transferred this technology and has
gained and licensed the skills from INRA to
enable us to certify varieties.
To certify your olive-tree or authenticate the main variety of olive present in your “extra vierge” olive oil :
|
-
Contact us to register your request.
-
Take a 20 cm long branch with about twenty leaves from
your tree, place it in an envelope, indicate the precise location of the tree
along with your name and address, or for oil send us a one litre bottle of your “extra virgin”
olive oil with details that allow us to identify the batch and send the
package to our laboratory address .
-
You will receive by mail indicating the variety of your olive-tree or the variety of olive present in your oil.

3. Microcystin quantification |
Microcystines are hepatotoxins produced by cyanobacteria. Those cyclic peptides are
a major public health issue as they are very toxic.
Their presence in water could be a danger to both
humans and animals (for example they can be found in cows milk ). The maximum limit allowed by the WHO is of 1µg/l for all microcystins.
Thus it is necessary to provide very accurate and sensitive tests. We can
provide :
|
-
A quantitative determination of microcystins in water samples by ELISA competition with a threshold of 0.147 ppb.
-
A measurement of detection limits of the test in other liquid samples (mainly milk samples) then makes a routine determination in this kind of samples.

Please contact the laboratory for any information you may need. |

4. Identification of foreign body |
|
Industrial food factories are sites where many products are coming in. They are
often very large places and it is sometimes difficult to
ensure a watertight or airtight environment. It is
therefore possible that undesirable components get into the
production chain .
Alongside continual improvement of production sites (as
often demanded by the end customer), it is also necessary to identify
the undesirable components to know where they came from and to adapt procedures if necessary .
We can help you to identify those animals or vegetable components. The use of well adapted protocols of DNA extraction allowed us to identify a fish-bone,
animal bone or other foreign body. This analysis is
quite uncommon, thus it is necessary to contact the laboratory to
give us information about the context in order to
decide the best way to proceed. |
