The document discusses foodborne diseases of animal origin, including: 1. Bovine tuberculosis caused by Mycobacterium tuberculosis, which can infect humans through infected animal products. 2. Brucellosis caused by Brucella abortus and B. melitensis, which can cause undulant or Malta fever in humans through contact with infected animals or consumption of contaminated food. 3. Several other diseases are described such as anthrax, listeriosis, campylobacteriosis, and Q fever, which can infect humans through consumption of contaminated animal products like milk, meat, or dairy. Proper food handling and hygiene are important for preventing transmission of these zoonotic diseases.

3.  When certain pathogen enters the food supply,
they can cause food borne illness.
 Millions of cases of food borne illness occur
each year.
 Very young children, pregnant woman, the
elderly and people with compressed immune
systems are at greatest risk.
 Most cases of food borne illness can be
prevented.

 It affects both human and animal (Zoonotic disease) and
can be classified into:
 Bacterial: e.g. Tuberculosis, Brucellosis, Anthrax, Listeriosis,
Yersiniosis, Campylobacteriosis and Udder infections.
 Viral: e.g. Rabies, FMD, Cow pox.
 Rickettsial: e.g. Q-Fever.
 Mycotic: e.g. Actinomycosis.

15. 1st method “complete elimination method”
 Applied in countries of low incidence of T.B.
(less than 10%). This method include testing
animals with tuberculin test, then elimination of
the reactors “+ve” by slaughtering, thus to
obtain tubercles free herd.

21. Disease in man
 Infected animal disseminate the organism in milk,
morbid secretion & excretion which may then
contaminate food.
 Man is infected either directly through contact with
diseased animal or indirectly through
consumption of infected food.
 The disease in man is characterized by febrile
condition (temperature are high at night & normal
in the morning and heart beats are irregular).
8/31/2020 Dr. Zeinab I. Ali 21

22. Control and preventive measures
A. Apply A.B.R. test on milk cans to detect the
organism in a certain animal.
B. Apply blood serum agglutination test to
determine the individual diseased animal.
C. Vaccination of calves at 6 month’s age by strain
19.
D. Heat treatment of produced milk.

very shortly before death, and mostly milk
secretion in such condition will stop due to the
febrile condition and weakness of the animal and
consequently there is rare or no chance for
transmission of the disease through milk.
