 Amendment of the Maximum Levels for contaminant s in feed commodities
（notification ） 
 
1. The Ministry of Agriculture, Forestry and Fisheries (MAFF) is proposing to 
establish or modify Maximum Levels  for contaminants in compo site feeds  or in 
their ingredients  for food producing  animals  on a basis of new  scientific data 
from surveillance/ monitoring  by MAFF . 
2. The proposed levels are set in accordance with the principle of “as low as 
reasonably achievable” , and ensuring that at the maximum levels, the 
contaminants of concern will not pose health risk to food producing animals or 
humans.  
 
Principle of ALARA is the international concept for setting the standards of 
contaminants, which s hows in the CODEX GENERAL STANDARD FOR 
CONTAMINANTS AND TOXINS IN FOOD AND FEED  (CGSCTFF ). 
 
3. In addition , MAFF will specify the food producing  animals  to which the feeds 
are to be given .  
 
The levels are described as follows /proposed changes is underlined :

(i) A maximum  limit is the maximum concentration of contaminant allowed in specified feed(s)  for distribution 
and expressed in mg/kg, d etection of a concentration above which will lead to ban of distribution of the feed.  
(ii) A maximum  level  is the maximum concentration of contaminant allowed in specified feed(s)  for distribution 
and expressed in mg/kg,  detection of a concentration above which will require  the Japanese Government to 
consider whether the feed should be recalled taking into account the probability of an adverse effect for food 
producing animals and /or human.  
(iii) for cattle, pigs, sheep, goats, deer, poultry  and quail s 
(iv) intentionally added to falsify the protein content in feed .
