Table 2 also serves to show that delay during the manufacture of 
pulp usually produces a rapid increase in the growth of organisms, 
noticeably yeasts and spores, or bacteria, or both, with the result 
that high counts are obtained for these organisms in the final product. 
This is well illustrated in Samples H 59, H 67, H 96a, and S 64. 
The absolute necessity of handling tomato products promptly in 
order to avoid secondary spoilage is shown in the case of Samples 
570 andS 78. Sample S 70 is the count on a sample of pulp freshly 
made, while Sample S 78 represents the same batch after standing 
24 hours. The counts are:
