1. TerminologyLot (quality) inspection The process of obtaining a representative sample(s) of

an identified rice lot, examining or testing the sample(s),

examining relevant records of the lot, and certifying the

results

Random sampling The taking of n items from a lot of N items in such a

way that all possible combinations of n items have the

same probability of being chosen.

Increment Individual portion of material collected by a single

operation of a sampling device.

Primary sample The collection of one or more increments or units

initially taken from a population.

Sub-sampling Process of selection of one or more sub-samples from a

sample of a population.

Composite sample Two or more increments/sub-samples mixed together in

appropriate portions, either discretely or continuously

(blended composite sample), from which the average

value of a desired characteristic may be obtained.

Homogeneity The degree to which a property or constituent is

uniformly distributed throughout a quantity of material.

Representative sample Sample resulting from a sampling plan that can be

expected to reflect adequately the properties of interest

in the parent population.

2. Sampling procedure

This part prescribes the sampling procedure which was followed by CAC inspection

team to ensure obtaining a representative sample.

A. Sampling

The required number of primary sampling units equal to 174 bags selected

randomly from the whole commodity.

All bags were labeled with the following information:

MAV00GB/GVA10/76765

IRRI-6 Long Grain White Rice , 5% broken

Origin : Pakistan

Net weight : 35 kg

Crop 2010/2011

Processed : 01/2011

Since the commodity comprised more than 10,000 bags, the whole quantity was

divided into 2 Sub-Lots and the number of bags from which samples were drawn

are 174 bags from the whole lot.

(United State Department of Agriculture (Rice Inspection Handbook)

B. Statistical assumption

- Homogeneity of the Lot.

- Zero Defective rates in the lot (C =0) , sampling plan used is

one in which the lot is only accepted if zero defectives occur

in the sample

- Probability of lot acceptance 100%

- The zero acceptance sampling plan nonconformance in

sample dose not imply that the lot is perfect

- Sufficient number of bags selected so as to be representative

of the consignment.

- Inspection Level , Level I is used since less discrimination is

required.

According to the Codex GENERAL GUIDELINES ON SAMPLING CAC/GL 50-

2004

The calculation of the adequate sample size as the following characteristics:

Container Size : 35 KG Polypropylene bags

Inspection Level : level I (The normal sampling level)

lot size : 15000 bags

Sampling Size : 174 bags to be inspected

Acceptance Number (C=0): Zero acceptance sampling plan.

Average sample increment weight (gm): 400-500 gm

CAC's team took random samples from all the containers and from different places

within the container in order to ensure that the random samples taken are

representative of the whole quantity.

C. Preparation of samples

Primary samples

CAC's team collected increment samples of approximately equal size randomly from

the 174 rice bags and placed in a clean dry polypropylene bag were portions taken

from various levels of the these stacks so as to obtain fairly representative sample of

the whole consignment

Composite sample (bulk sample )

CAC inspection team thoroughly mixed the incremental samples to form a single

homogenous composite sample.

Reduced samples

CAC inspection team reduced the sample size to a smaller size sample by the

reduction in weight of a larger quantity of the composite sample many times to reach

the final representative sample. The sub sample is usually divided equally into the

required number of portions, which are not only representative of the composite

sample but of the lot and to be submitted to the laboratory.

Final Samples

Two representative samples of weight 2.50 kg/each were finally obtained

NOTE: One sample for laboratory testing and the other to be kept in CAC.

2. Work Record

The results of all tests and findings of the laboratory were recorded clearly and

accurately herein to be evaluated and to be used as a source of information reported

on the inspection certificate.

A. Basis of Determination

The basis of determination is the representative samples submitted to the Industrial

Chemical Centre ICC competent laboratory.

1. The moisture test conducted according to SOP:13OM01-010 which was built

according to ISO 712:1998 Cereals and Cereal Products - Determination of

Moisture Content -- Routine Reference Method , ISO 712 specifies a routine

reference method for the determination of the moisture content of cereals and

cereal products. It is applicable to the following products: wheat, durum

wheat, rice (paddy, husked and milled rice), barley, millet .

2. The international standard ISO 7301 :2002 used for Rice –Specification where

a normative annex specifies the determination of extraneous matter, broken

kernels, defective kernels and other kinds of rice.

3. AOAC 972.26:2005 for monitoring grain contamination for the presence of

aflatoxins to ensuring consumer safety.

4. Helica Ochratoxin assay used to detect the quantity of Ochratoxin in rice

sample ,the Helica Ochratoxin Assay is competitive enzyme-linked

immunoassay intended for the quantitative detection of Ochratoxin levels in

grains, cereals, coffee, and other commodities including animal feeds.

5. According to Codex (CAC/GL 50-2004) procedure A is used as a default

procedure since its includes plans with acceptance number zero.

B. Preparatory Examination

Inspection of commodity in warehouse

CAC's team also inspected the warehouse of ICRC in abu-Alanda by looking any

signs of damage on the packaging of the commodities, evidence of insects or rodent

damage and also any signs of moist or cracking.

The inspection team conducted a visual inspection to the demotic lot ensuring the

following:

- Reviewing the size and physical layout of the lot.

- Examining the all visible sacks for animal filth, wetness, infestation and large

holes for the number of sacks are accessible for examination.

- Examining the rice odor by smelling the rice bags and the samples in the

warehouse and at the time of sampling for any objectionable foreign odor as a

whole and reviewing the information on the rice bags .

- The incremental samples were examined each separately for any objectionable

foreign odor that is not normal to rice such as musty , rancid, smoke and decaying

animal and vegetable matter odor.

- The incremental samples were examined for any live / dead insect at the time of

sampling.

- CAC representative observed the following when inspected the warehouse:

All the stacks were in good conditions.

The warehouse occupies about (6000) m2.

The infrastructure of the warehouse was suitable to store the food

consignments

3. Laboratory Test Results

The tests were conducted in the Industrial Chemical Centre (Organic Division-Food

Laboratory) for the submitted representative sample from ESCAD and the results

were obtained as specified in the table below

4. Evaluation of Test Results

a) Visual examination

1. Odor

ESCAD representative determined the odor of the rice in the ICRC warehouse for

the lot in general and for each incremental samples collected in particular at the

time of sampling by smelling , and made the final odor determination on the

composite sample taken ,as well as the reduced and the laboratory samples.

The inspection team identified that the rice polypropylene bags were clean ,dry

and off-odor detected by smelling.

2. Colour

ESCAD representative examined the whole kernels portion for color change

visually and found that the whole kernels of rice are distinctly discoloured

3. General shape

ESCAD representative recorded that the rice grains were in good shape for rice

kernels.

b) Quality criteria

The proven method used "Zero acceptance sample number" to decide whether or

not to accept or reject a production lot without checking every single item of the

lot performed on randomly-selected sample items. This method serves as a

measure for insuring quality where the AQL=6.5% and C=0 , for general

inspection level I, the Acceptance Number =0, the rejection number =1

The laboratory results obtained compared with the required value as illustrated in

the table below

good condition , sound ,clear and no insect infestation nor has rodent

or bird contamination or any other deteriorating conditions .

B. According to the laboratory test result above the risk analysis

undertaken to assess the probability and severity of toxins impacts on

public health and safety shows no any contamination occurred to the

shipment.

C. The quality factor tests for yellow grain as a result of heating shows

higher value (0.10) than the required value (max. 0.05 %) . And

according to different kinds of rice the max. level for such quality

factor shall not exceed 3% ( codex standard for rice ,codex stan 198-

1995 ) .

D. For the other tests the codex alimentations general guidelines on

sampling CAC/GL 50-2004 the probability of lot acceptance

concerning the consumer risk (CR). Generally, the CR is expressed

by a proportion noted as P10 which corresponds to the proportion of

defective items in the lot accepted in 10 % of the cases.
