Correct Answer :C. Acute Swine Erysipelas or Anthrax.
Comprehensive Explanation: The purposes of ante-mortem inspection include
eliminating animals unfit for food and preventing contamination of personnel,
premises, and equipment. An animal affected with a severe acute systemic
disease, such as Anthrax, Rinderpest, Blackleg, Hog Cholera, FMD, or Acute
Swine Erysipelas, must be immediately CONDEMNED.
According to post-mortem disposition rules regarding Cysticercus bovis (beef
tapeworm), a carcass found with a moderate infection may be passed for
human consumption under which specific condition?
A. The entire carcass is condemned because the lesions are considered
generalized and acute.
B. The affected parts are condemned, and the remainder of the carcass is
passed for refrigeration (cold storage) at -9.5 degree C or lower for a minimum
period.
C. The carcass is passed for sterilization by cooking at 76.6 degree C for a period
of not less than 30 minutes.
D. Only the cysts are removed, and the entire carcass is passed immediately for
normal market sale. –
Correct Answer :B. The affected parts are condemned, and the remainder of the
carcass is passed for refrigeration (cold storage) at -9.5 degree C or lower for a
minimum period.
Comprehensive Explanation: In cases of moderate infection with Cysticercus
bovis, the affected tissues surrounding the cysts must first be removed and

condemned. The remaining carcass can then be passed for food subject to
being held in cold storage at a temperature not higher than -9.5 degree C
continuously for a period not less than 10 days (20 days for boned meat),. This
procedure ensures the inactivation of the cyst and is categorized as "PASSED for
REFRIGERATION".
According to principles of humane slaughter, which step must be completed
using humane tools to render the animal unconscious and unable to feel pain,
prior to bleeding out the carcass on a rail?
A. Grading
B. Post-mortem inspection
C. Stunning
D. Rendering –
Correct Answer :C. Stunning
Comprehensive Explanation: Stunning is the action performed to render the
animal unable to feel the pain and sensations prior to slaughter. Legislation
often requires animals be rendered unconscious (stunned) by a humane tool
prior to bleeding. The basic methods of stunning include mechanical, electrical,
and carbon dioxide gas anesthesia,.
A major contributing factor to foodborne disease outbreaks in prepared food is
the failure to maintain proper storage temperatures. Which practice is
specifically listed as a common cause of foodborne outbreaks?
A. The use of carbon dioxide gas anesthesia during humane slaughter.
B. Insufficient washing of transport vehicles prior to farm entry.

C. Inadequate refrigeration or preparing foods too long before serving.
D. Microbial examination revealing non-specific infectious bacteria like
Enterococci. –
Correct Answer :C. Inadequate refrigeration or preparing foods too long before
serving.
Comprehensive Explanation: Commonly cited causes of foodborne outbreaks
involve mishandling of prepared food, specifically including inadequate
refrigeration, foods prepared too long before serving, infected persons
practicing poor personal hygiene, and inadequate cooking or heat processing,.
Listeriosis, caused by Listeria monocytogenes, is a foodborne disease of public
health concern. Outbreaks in ruminants are often related to the consumption of
contaminated feed, and human infection often results from contaminated food,
such as raw milk or soft cheeses. What food hygiene challenge does L.
monocytogenes present?
A. It is often shed in animal feces, contaminating pasture, but it cannot survive
outside the host.
B. Its ability to survive and replicate inside host macrophages inhibits cell-
mediated immunity.
C. Its tolerance to heat means it may survive the pasteurization process.
D. It requires specific anaerobic conditions for growth, limiting its spread in
aerobic environments. –
Correct Answer :C. Its tolerance to heat means it may survive the pasteurization
process.
