In an HTST pasteuriser, what happens when the milk temperature at the end of the holding tube falls below the set point?
A. The flow diversion valve sends the milk back to the raw side
The flow diversion valve is the automatic safeguard that returns under-heated milk for re-pasteurisation. Pressure in the regenerator must always be higher on the pasteurised side, never reversed.
The milk ring test is used to screen herds for:
D. Brucellosis
Stained Brucella antigen binds antibodies in milk that attach to the cream and form a coloured ring. TB uses the tuberculin test; mastitis uses SCC or CMT.
A bullock is found dead in the lairage with dark unclotted blood oozing from the nostrils and anus. What should be done?
A. Do not open the carcass; notify and arrange safe disposal as suspected anthrax
Opening an anthrax carcass exposes Bacillus anthracis to air so it forms resistant spores. Diagnosis is by a blood smear from a peripheral vessel under precautions; animals dead in lairage are unfit anyway.
Which parasite is acquired by eating raw or undercooked beef?
B. Taenia saginata
Cysticerci in beef give the beef tapeworm Taenia saginata. T. solium is from pork; Echinococcus comes from dog-passed eggs; Fasciola mainly from aquatic plants.
The Codex Alimentarius Commission was established by:
C. FAO and WHO
FAO and WHO created Codex in 1963. WTO later referenced Codex in the SPS Agreement, and WOAH sets animal health standards.
Which WTO agreement names Codex as the reference for food safety standards?
A. The Agreement on the Application of Sanitary and Phytosanitary Measures
The SPS Agreement names Codex for food safety, WOAH for animal health and IPPC for plant health. TBT covers other technical regulations such as labelling beyond safety.
Which process gives a commercially sterile milk that can be stored at room temperature?
C. UHT treatment at about 135 °C or more for a few seconds with aseptic packaging
UHT with aseptic packaging destroys spores to commercial sterility. Pasteurised milk still contains spores and needs refrigeration; thermisation is milder still.
Which mould produces aflatoxins?
B. Aspergillus flavus
Aspergillus flavus and A. parasiticus produce aflatoxins. Fusarium makes deoxynivalenol and zearalenone; Claviceps causes ergotism.
