following conditions:  
(a) The product assessment shall pay particular 
attention to the exposures, the risks and the efficacy 
linked to any uses covered by an application for 
authorisation, but n ot addressed in the Unio n level 
risk assessment of the active substance.  
(b) In the light of the outcome of the risk assessment for 
the uses assessed, t he product assessment shall pay 
particular attention to:  
(1) professional  users ; 
(2) sediment and soil following disinfection of 
vehicles used for animal transport and 
disinfection in hatcheries after fogging 
treatment . 
(c) For products that may lead to residues in food or 
feed, the need to set new or to amend existing 
maximum residues levels (MRLs) in accordance 
with Re gulation (EC) No 470/2009  of the European

1 The purity indicated in this column was the minimum degree of purity of the active substance evaluated. The active substance in the product placed on the market can be of 
equal or different purity if it has been proven to be technically equivalent to  the evaluated active substance.   
2 Regulation (EC) No 470/2009 o f the European Parliament and of the Council of 6 May 2009 laying down Community procedures for the establishment of residue limits of 
pharmacologically active substances in foodstuffs of animal origin , repealing Council Regulation (EEC) No 2377/90 and ame nding Directive 2001/82/EC of the European

(a) The product assessment shall pay particular 
attention to the exposures, the risks and the efficacy 
linked to any uses covered by an application for 
authorisation, but not a ddressed in the Unio n level 
risk assessment of the active substance.  
(b) In the light of the outcome of the risk assessment for 
the used assessed, t he product assessment shall pay 
particular attention to:  
(1) professional us ers; 
(2) sediment and soil following disinfection in 
slaughterhouses and butcheries.  
(c) For products that may lead to residues in food or 
feed, the need to set new or to amend existing 
MRLs in accordance with Regulation (EC) No 
470/2009 or Regulation (EC) No 396/ 2005 shall be 
verified, and any appropriate risk mitigation 
measures shall be taken to ensure tha t the applicable 
MRLs are not exceeded.  
(d) Didecyldimethyl ammonium chloride  shall not be 
incorporated in materials and articles intended to 
come into contact with food falling within the scope  
of Regulation (EC) No 1935/2004  of the European 
Parliament and of the Council4, unless the

EN 3  EN Commission has established specific limits on t he 
migration of didecyldimethyl ammonium chloride 
into food or it has been established pursuant to that 
Regulation that such limits are not necessary.
