2. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 2 Training Session Product File Notes and Registration Reports Overview When is the residue part relevant? Contents of a Product File Note:  Key information about the a.s.  Setting of MRLs  Consumer exposure assessment  Additional studies relevant to the assessment

3. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 3 Training Session Product File Notes and Registration Reports When is the residue part relevant ? PPP residues are likely to occur in food commodities of plant and animal origin Example: residue data are required on feedingstuffs but not on ornementals or herbicides used on lawns, pavements, streets, railways… From an administrative point of view, the following requests are concerned:  Application for a new registration  Application for an additional use  Application for the modification of an existing use (shorter PHI, increase in the number of application, higher dose rate)

4. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 4 Training Session Product File Notes and Registration Reports Key information about the a.s. (1) Toxicological endpoints: consumer intake assessment  Acceptable Daily Intake (ADI): long-term risk assessment  Acute Reference Dose (ARfD): short-term risk assessment (if necessary) Sources of toxicological endpoint Depending on the status of the a.s. under EU review:  Review Report  EFSA scientific report  Last updated list of endpoints  DAR

5. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 5 Training Session Product File Notes and Registration Reports Key information about the a.s.(2) Other sources of toxicological endpoints:  European MRL proposals (Working Group Pesticides Residues)  JMPR recommendations  Toxicological endpoints: values set by Scientific Institute of Public Health (Belgian Registration Committee)  Submitted residue dossier Overview of toxicological endpoints:  Doc. 3010: combines EU and JMPR endpoints, but not updated regularly

6. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 6 Training Session Product File Notes and Registration Reports Key information about the a.s.(3) Residue definition for products of plant and animal origin :  Parent compound only  Parent compound + significant metabolites  Metabolites only Crop categories tested :  Five crop categories: root and tuber vegetables, leafy crops, pulses and oilseeds, fruits, cereals  Studies for crops from 3 categories indicate a similar metabolic pathway no more studies are needed

7. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 7 Training Session Product File Notes and Registration Reports Key information about the a.s.(4) Farm animals tested :  Ruminants: lactating cows or goats  Poultry: laying hens  If studies on ruminants and poultry are available,and metabolism is similar with rats Extrapolation to all the animal commodities (meat, fat, edible offals, milk and eggs) What we expect:  List of all the available metabolism studies + sources  Intended uses must be covered

10. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 10 Training Session Product File Notes and Registration Reports Setting of MRLs (1) 1 ) a.s. with Community MRLs (harmonised a.s.) Procedure: An European MRL was established for the proposed use The proposed GAP is comparable to or less critical than the GAP defended at European level Yes No 2) a.s. with national MRLs (unharmonised a.s.) A complete residue data set is always needed for each applicant No further assessment is needed = the use is covered by the European evaluation A complete residue data set is needed

11. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 11 Training Session Product File Notes and Registration Reports Setting of MRLs (2) Principles for filling in the Product File Note  Crop: a distinction must be made between field uses and protected uses ; a full data package is required for the critical situation  Proposed critical GAP: the critical practice (highest dose rate, shortest PHI, maximum number of applications) must be identified in the biology part  Residue trials: number of trials complying with the critical GAP (taking into account the 25% tolerance rule). Must be GLP and analytical methods fully validated.

12. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 12 Training Session Product File Notes and Registration Reports Setting of MRLs (3) Principles for filling in the Product File Note  Extrapolations: trials results obtained on a crop can support the use on an another comparable crop (see guideline)  MRLs for animal products: livestock feeding studies are usually performed on ruminants (lactating cows or goats) and poultry (laying hens). Dietary burden must be stated.

15. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 15 Training Session Product File Notes and Registration Reports Consumer exposure assessment (1) Models used for the chronic exposure  WHO European diet for adults (1994)  German VELS model for children aged 2-5 years (2005)  UK PSD model for ten consumer groups: adults, infants, toddlers, children (further split into 4-6 year old, 7-10 year old, 11-14 year old and 15-18 year old, vegetarians, elderly (own home), elderly (residential) (2006) The 3 models must lead to an acceptable exposure: < 100% ADI

16. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 16 Training Session Product File Notes and Registration Reports Consumer exposure assessment (2) Models used for the acute exposure  German VELS model for children aged 2-5 years (2005)  UK PSD model for ten consumer groups: adults, infants, toddlers, children (further split into 4-6 year old, 7-10 year old, 11-14 year old and 15-18 year old, vegetarians, elderly (own home), elderly (residential) (2006) For any proposed use, the 2 models must lead to an acceptable exposure: < 100% ARfD

21. Federal Public Service ‘Public Health, Food Chain Safety and Environment’ 23 October 2006 21 Training Session Product File Notes and Registration Reports Additional studies  Metabolism in plants and livestock: only when residue definitions are not covering the requested uses (see key information about the a.s.)  Stability of the residue during storage: when registration is sought in a certain crop group (water, oil, starch, protein or animal products), unless it has been adressed previously.  Processing studies: depending on the exposure to residues and the relevance of processed products, nature and level of residues in processed products must be adressed.  Rotational crops: when resistration is sought in a rotational crop, unless it has been adressed previously.
