MEDICAL MILK COMMISSIONS AND CERTIFIED MILK. 37 
disease has developed. On receipt of the notice this committee shall assume 
charge of the matter, and shall have power to act for the commission as its 
judgment dictates. As soon as possible thereafter, the committee shall notify 
the commission, through its secretary, that a special meeting may be called for 
ultimate consideration and action. 
96. When a case of contagious disease is found among the employees of a 
dairy producing certified milk under the control of a medical milk commission, 
such employee shall be at once quarantined and as soon as possible removed 
from the plant, and the premises fumigated. 
When a case of contagion is found on a certified dairy it is advised that a 
printed notice of the facts shall be sent to every householder using the milk, 
giving in detail the precautions taken by the dairyman under the direction of 
the commission, and it is further advised that all milk produced at such dairy 
shall be heated at 145° F. for 40 minutes, or 155° F. for 30 minutes, or 167° F. 
for 20 minutes, and immediately cooled to 50° F. These facts should also be 
part of the notice, and such heating of the milk should be continued during the 
accepted period of incubation for such contagious disease. 
The following method of fumigation is recommended: 
After all windows and doors are closed and the cracks sealed by strips of 
paper applied with flour paste, and the various articles in the room so hung 
or placed as to be exposed on all sides, preparations should be made to generate 
formaldehyde gas by the use of 20 ounces of formaldehyde and 10 ounces of 
permanganate of potash for every 1,000 cubic feet of space to be disinfected. 
For mixing the formaldehyde and potassium permanganate a large gal- 
vanized-iron pail or cylinder holding at least 20 quarts and having a flared 
top should be used for mixing therein 20 ounces of formaldehyde and 10 ounces 
of permanganate. A cylinder at least 5 feet high is suggested. The containers 
should be placed about in the rooms and the necessary quantity of permanga- 
nate weighed and placed in them. The formaldehyde solution for each pail 
should then be measured into a widemouthed cup and placed by the pail in 
which it is to be used. 
Although the reaction takes place quickly, by making preparations as advised 
all of the pails can be " set off" promptly by one person, since there is nothing 
to do but pour the formaldehyde solution over the permanganate. The rooms 
should be kept closed for four hours. As there is a slight danger of fire, the 
reaction should be watched through a window or the pails placed on a nonin- 
flammable surface. 
97. Following a weekly medical inspection of the employees, a monthly report 
shall be submitted to the secretary of the medical milk commission, on the same 
recurring date by the examining visiting physician. 
The following schedule, filled out in writing and signed by himself, is recom- 
mended as a suitable form for the attending physician's report :
