EXAMINATION OF SHELLFISH 257 



which were adopted by the Association at its meet- 

 ing in 1912: 



RECOMMENDATIONS FOR STANDARD METHODS FOR THE 

 BACTERIOLOGICAL EXAMINATION OF SHELLFISH 



Oysters in the Shell 



Selection of Sample. Twelve (12) oysters of the average 

 size of the lot under examination, with deep bowls, short 

 lips, and shells tightly closed, shall be picked out by hand 

 and prepared for transportation to the laboratory. 



As complete a record of such data as is possible to obtain 

 shall be made covering the following points : 



The exact location of the bed from which the sample 

 has been selected. 



The depth of the water over the bed at time of collection. 



The state of the tide. 



The direction and velocity of the wind. 



Other weather conditions. 



The day and hour of the removal of the stock from the 

 water. 



The conditions under which the stock has been kept 

 since removal from the water and prior to the taking of 

 the sample. 



The day and hour of the taking of the sample. 



Transportation of the Sample. The oysters so selected 

 shall be packed in suitable metal or pasteboard containers 

 of such size and shape that a number of them can be 

 enclosed in a shipping case capable of satisfactory refriger- 

 ation by means of ice. The important points in this con- 

 nection are: 



A. The prevention of the mixing of the oyster liquor 

 of different samples, and of the mixing of the ice-water 

 with the oysters.
