 constructed and operated aocprding to plans approved by the commission. 

 A separate bed shall be provided for each milker and each bed shall be kept 

 supplied with clean bedclothes. Proper bathing facilities shall be provided 

 for all employees on the dairy premises, preferably a shower-bath, and fre- 

 quent bathing shall be enjoined. 



93. In case the employees live on the dairy premises a suitable building 

 shall be provided to be used for the isolation and quarantine of persons under 

 suspicion of having a contagious disease. 



The following plan of construction is recommended: 



The quarantine building and hospital should be one story high and con- 

 tain at least two rooms, each with a capacity of about 6000 cubic feet and 

 containing not more than three beds each, the rooms to be separated by a 

 closed partition. The doors opening into the rooms should be on opposite 

 sides of the buUding and provided with locks. The, windows should be 

 barred and the sash should be at least 5 feet from the ground and constructed 

 for proper ventilation. The walls should be of a material which will allow 

 proper disinfection. The floor should be of painted or washable wood, pref- 

 erably of concrete, and so constructed that the floor may be flushed and 

 properly disinfected. Proper heating, lighting, and ventilating facilities 

 should be provided. 



94. In the event of any illness of a suspicious nature the attending 

 physician shall immediately quarantine the suspect, notify the health author- 

 ities and the secretary of the commission, and examine each member of the 

 dairy force, and in every inflammatory affection of the nose or throat occur- 

 ring among the employees of the dairy, in addition to carrying out the above- 

 mentioned program, the attending physician shall take a culture and have 

 it examined at once by a competent bacteriologist approved by the com- 

 mission. Pending such examination, the affected employee or employees 

 shall be quarantined. 



95. It shall be the duty of the secretary, on receiving notice of any sus- 

 picious or contagious disease at the dairy, at once to notify the committee 

 having in charge the medical supervision of employees of the dairy farm upon 

 which such disease has developed. On receipt of the notice this committee 

 shall assume charge of the matter, and shall have power to act for the com- 

 mission as its judgment dictates. As soon as possible thereafter, the com- 

 mittee shall notify the commission, through its secretary, that a special meet- 

 ing 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 commis- 

 sion, 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 mUk, 

 giving in detail the precautions taken by the dairjrman under the direction 

 of the commission, and it is further advised that all milk produced at such 

 dairy shall be heated at 14.5° F. for forty minutes, or 155° F. for thirty min- 

 utes, or 167° P. for twenty 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 dis- 

 ease. 



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 formaldehyd gas by the use of 20 ounces of formaldehyd and 10 

 ounces of permanganate of potash for every 1000 cubic feet of space to be 

 disinfected. 



For mixing the formaldehyd and potassium permanganate a large gal- 

 vanized-iron pail or cylinder holding at least 20 quarts and having a flared
