What this subject covers

Prerequisite programmes, HACCP and the certified food safety systems dairy buyers and regulators require.

In the exams: ICAR AICE subject 35b Unit 1, subject 34 Unit 9 and subject 37 Unit 9; ICAR AIEEA-PG group 16 (ISO 9001 and ISO 22000)

What ICAR AIEEA-PG asks from it

ICAR AIEEA-PG — Dairy Science (group 16) and Dairy Technology (group 17)

Group 16 names ISO 9001 and ISO 22000 and plant hygiene; group 17 Unit I names HACCP in fluid milk. Expect recall of the seven principles, the twelve steps, pasteurisation as a CCP, flow diversion and phosphatase verification.

Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.

1 · Prerequisite programmes and good manufacturing practice · easy

In a food safety management system, prerequisite programmes are best described as:

  1. Legal limits for contaminants that a regulator sets for each category of dairy product
  2. Laboratory tests on finished product that release each batch for dispatch to customers
  3. Control measures with critical limits applied at specific steps of the process flow
  4. Basic conditions and activities that keep a hygienic environment across the operation
Answer and working

D. Basic conditions and activities that keep a hygienic environment across the operation

PRPs (Codex good hygiene practices, US CGMPs) control the general environment: premises, water, pests, people, cleaning, maintenance. Control measures with critical limits at specific steps are CCPs; release testing and legal limits are separate tools.

2 · Prerequisite programmes and good manufacturing practice · easy

Which document published by Codex contains both the good hygiene practices and the HACCP annex used worldwide?

  1. Code of Practice for the Reduction of Aflatoxin in Feed
  2. General Standard for the Use of Dairy Terms
  3. General Standard for the Labelling of Prepackaged Foods
  4. General Principles of Food Hygiene, CXC 1-1969
Answer and working

D. General Principles of Food Hygiene, CXC 1-1969

CXC 1-1969, revised in 2020, holds the GHPs and the HACCP system and guidelines. The dairy-terms standard protects dairy names, the labelling standard covers labels, and the aflatoxin code addresses feed.

3 · HACCP: the seven principles and twelve steps · easy

Which is the first of the seven HACCP principles?

  1. Determine the critical control points
  2. Assemble the HACCP team
  3. Construct a flow diagram
  4. Conduct a hazard analysis
Answer and working

D. Conduct a hazard analysis

Principle 1 is hazard analysis. Determining CCPs is principle 2; assembling the team and drawing the flow diagram are preliminary steps 1 and 4, not principles.

4 · HACCP: the seven principles and twelve steps · medium

Which of these is a critical limit rather than a monitoring procedure at an HTST pasteuriser?

  1. A recorder chart reviewed and signed each day
  2. Testing the flow diversion valve at start-up
  3. Reading the indicating thermometer each hour
  4. Minimum holding-tube outlet temperature
Answer and working

D. Minimum holding-tube outlet temperature

A critical limit is the value that separates acceptable from unacceptable, such as the minimum holding temperature. Hourly readings and recorder charts are monitoring; testing the diversion valve is verification.

5 · HACCP: the seven principles and twelve steps · medium

Why does HACCP prefer process control to end-product testing for low-rate contamination?

  1. Small samples miss low-rate defects
  2. End-product testing is prohibited by Codex for ready-to-eat dairy products
  3. Laboratory methods cannot detect pathogens in milk products at any concentration
  4. Process control removes the need for any laboratory verification of products
Answer and working

A. Small samples miss low-rate defects

With low prevalence, a few samples will usually all be negative even if some units are contaminated. Methods can detect pathogens, Codex does not prohibit testing, and HACCP still uses testing as verification.

6 · HACCP plans for pasteurised milk, cheese, powder and ice cream · easy

In an HTST pasteuriser, which device returns milk that has not reached the set holding temperature to the balance tank?

  1. The regenerator section
  2. The flow diversion valve
  3. The timing pump
  4. The homogeniser
Answer and working

B. The flow diversion valve

The flow diversion valve diverts sub-temperature milk. The timing pump fixes maximum flow and so minimum holding time; the homogeniser reduces fat globule size; the regenerator exchanges heat between raw and pasteurised milk.

7 · HACCP plans for pasteurised milk, cheese, powder and ice cream · easy

Which test on finished milk is used to verify that pasteurisation was adequate?

  1. Alcohol stability test
  2. Methylene blue reduction test
  3. Alkaline phosphatase test
  4. Clot-on-boiling test
Answer and working

C. Alkaline phosphatase test

Alkaline phosphatase is inactivated by correct pasteurisation, so a negative result verifies the heat treatment. Methylene blue reduction estimates bacterial activity in raw milk; alcohol and clot-on-boiling tests judge heat stability of raw milk.

8 · HACCP plans for pasteurised milk, cheese, powder and ice cream · medium

In a cheese plant, why is the rate of acid development in the vat often monitored as a control?

  1. pH measurement replaces the need for pasteurisation of the cheese milk
  2. Acid development indicates the fat content of the cheese milk
  3. Slow acidification lets Staphylococcus aureus form enterotoxin
  4. Fast acidification destroys the rennet and stops curd formation
Answer and working

C. Slow acidification lets Staphylococcus aureus form enterotoxin

A slow vat, from phage or antibiotic residues, allows S. aureus growth and toxin formation, so pH at set times is monitored. Acid does not destroy rennet in normal ranges, pH does not show fat content, and pH monitoring does not replace pasteurisation.

9 · ISO 22000 and FSSC 22000 · easy

Which edition of ISO 22000 introduced the high-level structure shared with ISO 9001?

  1. 2018
  2. 2011
  3. 2015
  4. 2005
Answer and working

A. 2018

ISO 22000:2018 adopted the high-level structure. The first edition was 2005; 2015 is the ISO 9001 revision year; 2011 is not an ISO 22000 edition.
