f. Brucella Species. Brucellosis is the name applied to the disease caused by
members of the group of organisms known as Brucella. This disease is spread by
contact with infected material or by consumption of raw milk from diseased animals.
Brucellosis is most commonly found in rural areas where raw milk is used. The
causative organisms are destroyed easily when milk is pasteurized.
g. Leptospira Species. Leptospirosis is a spirochetal infection. Mild attacks in
man resemble influenza. Leptospira organisms have been found in the milk of diseased
cows. There is some doubt that such milk is a source of the disease in man. As milk
has a lytic action on the organisms, they are gradually disintegrated.
h. Coxiella burnetii. This organism causes Q fever, a pneumonia-like disease
of rickettsial origin. The organism has been isolated from raw milk. Butter made from
unpasteurized milk has also been found to be a source of the disease. This organism is
one of the organisms most resistant to pasteurization. Therefore, proper relationships
of time and temperature must be carefully observed to ensure its destruction.
4-20. OXIDATIVE RANCIDITY
If this condition exists in severe quantities, a potential health hazard may exist.
For a discussion of the hazard of oxidative rancidity in foods, see paragraph 2-14.
4-21. HYDROLYTIC RANCIDITY
If this condition exists in severe quantities, a potential health hazard may exist.
4-22. DEHYDRATION
Dehydration does not present a potential health hazard. This condition, in severe
cases, may make the item unsuitable for its intended use.
4-23. FREEZE DAMAGE
Freeze damage does not present a potential health hazard. This condition, in
severe cases, may make the item unsuitable for its intended use.
4-24. FOREIGN MATERIAL
Foreign material must exceed certain formal guidelines to present a potential
health hazard. The type of foreign material found on the product will also determine the
health hazard potential.
