Food quality assurance

What is quality?

„ The totality of features and

characteristics of a product

or service that bear on its

ability to satisfy stated or

implied needs

International Organization for Standardization (ISO) Standard 8402

Wholesome food:

„ Nutritious

„ Safe

„ Palatable

Microbiological testing

„ Useful for controlling quality

„ Not very useful for controlling

food safetyfood safety

Control procedures

„ Inspections

„ Check for compliance with GMP and

SOP

„ SS ampling plansli l

„ Check for product compliance with

quality criteria

„ HACCP

„ Focus on process adjustments for

controlling food safety hazards

Sampling

Observation of a set amount of

product (lot) resulting in the

separation of lot units or portionsseparation of lot units or portions

for further testing

„ n = No. sample units to be

tested

„ c = No sample units allowed

Two-class plans

„ c = No. sample units allowed

to yield unsatisfactory results

„ Example: n = 5, c = 2

Two-class plans

n = 5, c = 2

„ n = No. sample units to be tested

„ c = No. sample units allowed >m but

<M

Three-class plan

„ m = Acceptable level of the test

organism

„ M = Level above which the sample

unit is unacceptable

„ Example: n = 5, c = 2, m = 10^2 , M =

Operating Characteristic Curve

Multiple plans

„ The lot is accepted or rejected on the

basis of a sequential decision

„ Example:

„ Coliforms in cooked ham (<10 MPN/g) „ n 1 =10, c 1 =0; n 2 =6, c 2 = „ 10 samples tested

  • Lot rejected if 1 or more samples have 10 MPN/g
  • Lot accepted if all 10 have <10 MPN/g „ If the lot is accepted, 6 more samples are collected
  • Lot rejected if 1 or more have 10 MPN/g
  • Lot accepted if all 10 have <10 MPN/g
