Products and All products handled by participants listed in this publication meet the specific require- 



Classifications ments for a "U.S. Pullorum-Typhoid Clean" classification. The combined letter and 



numeral symbols shown in the fourth column identify the particular breed, strain, or 

 trade name of the participant's products (see tables 4 and 5 in the appendix). Crosses 

 are designated by combining the letter symbols and code numbers of both parent 

 stocks, listing the male first. Thus a t9t18 code would indicate that the participant was 

 handling a cross consisting of a Hubbard male mated to a Pilch female. Additional 

 classifications for which these products qualify are identified in column five by MG, 

 "U.S. M. Gallisepticum Clean"; MS, "U.S. M. Synoviae Clean"; MM. "U.S. M. 

 Meleagridis Clean"; SAN MON, "U.S. Sanitation Monitored': and SE, "U.S. Salmonella 

 enteritidis Monitored."
