During the visit at the plant personal attention was given to the 
cleaning operations. Wherever possible without handicapping the 
operations of the factory, changes were made by which the apparatus 
was more easily and effectively reached for cleaning. In some cases 
wooden piping was changed, doors put in conveyors, pulp boxes made 
removable, and other changes were made by which the workmen 
could clean the various parts more quickly and efficiently. 
After these improvements had been made a change was noticed 
in the odor about the factory, especially when the steam hose was in 
use. The offensive, fetid odor, which had been noticeable in the ris- 
ing vapors whenever the steam hose was used, almost wholly dis- 
‘appeared, and in its place came the characteristic odor of fresh | 
tomato pulp. 
Factory No. 2. 
A faulty sorting system was the cause of the high counts present 
in the product manufactured by another factory visited. by the 
bureau’s representatives. ‘This condition is more general than the 
existence of inadequate cleaning systems. 
Tt was brought to the attention of the Bureau of Chemistry 
that this factory was having difficulty in maintaining low counts on 
its products. On visiting the plant it was found that the tomatoes 
were dumped into a soaking tank, from which they were carried up 
by a conveyor and fed into a rotary washer, covered with a screen of 
too fine a mesh to allow its being as efficient in removing soft rot as 
is necessary. From this washer the tomatoes were fed to the sorting 
apron. This apron was so arranged that at intervals along its length 
a portion of the main stream of tomatoes was diverted through the 
scalding boxes and out upon the peeling tables. Three sorters were 
working at the main sorting apron, but were so stationed that the 
tomatoes diverted to the first table received little or no sorting inspec- 
tion. Those for the second table received some attention, while those 
for the third had the greatest amount. The sorters also were trying 
to do trimming work. The result was that many spotted tomatoes
