Agricultural Product Standards Act, 1990 (Act No. 119 of 1990)RegulationsGrading, Packing and Marking of Eggs intended for sale in the Republic of South AfricaPart IV : Sampling and Examination15. Methods of examination |
(1) | The methods to be employed when a sample referred to in regulation 14, is examined in order to determine the extent to which eggs, with a defect referred to in regulation 5 are present in the quantity of eggs from which that sample is taken shall be as follows: |
(a) | Subject to the provisions of sub-regulation (2)— |
(i) | each egg in the sample shall be numbered; |
(ii) | each egg in that sample shall be examined visually in terms of external defects and where applicable by means of a suitable candling device with which internal defects can be observed; and |
(iii) | the depth of the air cell of an egg shall be determined as follows: |
(aa) | A calibrated measuring plate shall be placed on the broad end of the egg while it is held vertically against the candling device with the broad end at the top. |
(bb) | The value on the calibrated measuring plate shall be read off opposite the lower meniscus of the air cell. |
(cc) | Such reading shall represent the depth of the air cell of the egg concerned; or |
(dd) | The inspector inspecting the eggs may choose to use the Haugh value determined in accordance with the method set out in regulation 16 instead. |
(b) | Eggs with defects shall— |
(i) | be removed from the sample if the egg is examined individually and thereafter replaced into its numbered place; |
(ii) | not be replaced into its numbered place after it has been broken open; and |
(iii) | each separate number of eggs with each deviation shall be determined separately. |
(c) | Each number thus determined shall be expressed as a percentage of the number of eggs thus inspected. |
(d) | Such percentage shall represent the percentage of eggs in the quantity concerned in which a defect of the type concerned occurs. |
(2) | If it appears from an examination in terms of sub-regulation (1) that an egg thus examined has a particular internal defect, that egg may be broken open in order to verify the occurrence of the defect concerned. |
