Changes to authorisations for products containing chlorpyrifos

Regulatory Update: 03/2016
Issued: 12th February 2016


To advise of changes to authorisations for products containing chlorpyrifos.


Following a European Union review, new human health based safety levels (known as endpoints) were agreed in 2015 for chlorpyrifos, an insecticide used to control insect pests in agricultural crops and amenity situations.

Risk assessments carried out by the Health and Safety Executive (HSE) and endorsed by the Expert Committee on Pesticides (ECP) have indicated that most currently authorised uses of chlorpyrifos exceed these newly agreed endpoints.

As a result, with the co-operation of product authorisation holders, HSE are taking action to withdraw these uses from the market.

The Changes

  • With effect from 1st April 2016 the only permitted use of chlorpyrifos will be the protected brassica seedling drench treatment applied via automated gantry sprayer.
  • All other uses of chlorpyrifos are withdrawn with effect from 1st April 2016.
  • Storage, disposal and relabelling of any existing chlorpyrifos stocks must be completed by 1st October 2016.

HSE and product authorisation holders are taking prompt action now to communicate these changes in use through the supply chain, to ensure that re-labelling or any required reversal of the supply chain can be implemented as smoothly as possible.

Based on the conclusions of our risk assessments, we do not expect an effect on the health of operators, or other individuals, who may have been exposed to chlorpyrifos during the now withdrawn uses.

Likewise, we do not expect an effect on human health from any commodities previously treated with chlorpyrifos, or those imported commodities treated in future originating from other countries where applicable EU Maximum Residue Levels are met.
