Question

Which of the following is the most important microbial hazard during the storage of concentrated milk in feed tank in the manufacture of dried milks?

• A. Staphylococcus enterotoxin
• B. Fungal toxins
• C. Clostridium neurotoxins
• D. Bacteriocine

Hint:

Staphylococcus enterotoxin: major hazard.
Heat-stable toxin.
Proper temperature control is essential.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Concentrated milk storage can allow microbial growth.
Some bacteria produce toxins.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the microbial hazards in milk processing.
Step 3: Detailed Explanation:
Staphylococcus enterotoxin is the most important microbial hazard.
Staphylococcus aureus can grow in concentrated milk.
It produces heat-stable enterotoxins.
Fungal toxins are less common.
Clostridium neurotoxins are not typically associated.
Bacteriocines are not toxins.
Thus, Staphylococcus enterotoxin is the most important hazard.
Step 4: Final Answer:
Staphylococcus enterotoxin is the most important microbial hazard.
Hence, the correct option is (A). \bigskip
