Yunnan Sourcing takes your health seriously!  That’s why starting in October 2013 all of the Pu-erh teas produced under the Yunnan Sourcing brand (云之源) will be 100% compliant with the EU’s Food Safety Commission!  We decided to use the EU MRL as our standard because it’s the most stringent in the world!  


Yunnan Sourcing LLC guarantees that all Pu-erh teas produced under the Yunnan Sourcing Brand label from October 2013 onward comply with the European Commission's Safety Standards for Pesticide content.


The tea has been tested in a certified MRL (maximum residue limit) laboratory for 26 of the most common types of pesticides and did not exceed the limit set by the European Commission for Food Safety (as of October 2013).


For more information about the European Commission's safety standards for pesticides in tea see below.

Method:  This is laboratory method used to test for the pesticide.


Report Limit:  This is the amount below which the MRL test is not able to detect.  It’s 10 ppm (0.01 mg/kg) in most cases.


EU (MRL) Limitation:  This is the Maximum Residue Limit for the given pesticide in Tea (code 0610000) set by the EU Commission on Food Safety.  If a tea exceeded this limitation we would not produce it or sell it under the Yunnan Sourcing Brand label.


The MRL for each of the pesticides we tested for below can also be found at the EU Pesticides Database by following this address:  http://ec.europa.eu/sanco_pesticides/public/?event=substance.selection

 

If any levels of of DDT, DDD, or DDE (06-1, 06-2, 06-3, 06-4, 06-5) are detected (even if they are within the EU Limitation) Yunnan Sourcing LLC will not allow this tea to be used or included in our branded productions.
