iDevelopment of the East African Standards has been necessitated by the need for harmonizing requirements governing quality of products and services in East Africa. It is envisaged that through harmonized standardization, trade barriers which are encountered when goods and services are exchanged within the Community will be removed.
In order to meet the above objectives, the EAC Partner States have enacted an East African Standardization, Quality Assurance, Metrology and Test Act, 2006 (EAC SQMT Act, 2006) to make provisions for ensuring standardization, quality assurance, metrology and testing of products produced or originating in a third country and traded in the Community in order to facilitate industrial development and trade as well as helping to protect the health and safety of society and the environment in the Community.
East African Standards are formulated in accordance with the procedures established by the East African Standards Committee. The East African Standards Committee is established under the provisions of Article 4 of the EAC SQMT Act, 2006. The Committee is composed of representatives of the National Standards Bodies in Partner States, together with the representatives from the private sectors and consumer organizations. Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the Partner States. The comments received are discussed and incorporated before finalization of standards, in accordance with the procedures of the Community.
Article 15(1) of the EAC SQMT Act, 2006 provides that “Within six months of the declaration of an East African Standard, the Partner States shall adopt, without deviation from the approved text of the standard, the East African Standard as a national standard and withdraw any existing national standard with similar scope and purpose”.
East African Standards are subject to review, to keep pace with technological advances. Users of the East African Standards are therefore expected to ensure that they always have the latest versions of the standards they are implementing.

1For the purpose of this East African Standard, the following definitions shall apply.
whole or broken kernels of paddy rice (Oryza glaberrima, Digitaria exilis, Oryza sativa, Oryza longistaminata)
in the context of this standard, cereals refer to wheat, barley, oats, cereal rye, triticale, sorghum, maize and rice
all organic and inorganic material other than pearl millet, broken kernels, other grains and filth.
grains eaten in part by stored grain insects and any field pests of grains including Heliothis spp. Grains may have a hole (commonly referred to as bored) or have a chewed appearance on any part of the grain.
an estimate of the quantity of whole kernels and total milled rice (whole and broken kernels combined) that are produced in the milling of rough rice to a well-milled degree.
refers to defective grains caused by overheating during artificial drying. It can be detected where grain is hot, exhibits an unusual odour, exhibits significant sprouting (greater than 10%) or other evidence of weather damage
whole or broken unhulled kernels of rice; whole or broken kernels of brown rice, and whole or broken kernels of milled rice having a portion or portions of the hull remaining which cover 12.5 % or more of the whole or broken kernel
rough rice in which the starch has been gelatinized by soaking, steaming, and drying. Grades 1 to 4 inclusive, shall contain not more than 10.0 percent of ungelatinized kernels. Grades 1 and 2 shall contain not more than 0.1 percent, Grades 3 and 4 not more than 0.2 percent of nonparboiled rice. If the rice is:
any seed which if present in quantities above permissible limit may have damaging or dangerous effect on health, organoleptic properties or technological performance such as Jimson weed — dhatura (D. fastuosa Linn and D. stramonium Linn.) corn cokle (Agrostemma githago L., Machai
2Lallium remulenum Linn.) Akra (Vicia species), Argemone mexicana, Khesari and other seeds that are commonly recognized as harmful to health
rough rice which contains more than 3.0 percent of smutty kernels
There are four classes of rough rice. The following four classes shall be based on the percentage of whole kernels, and types of rice:
Long Grain Rough Rice.
Medium Grain Rough Rice.
Short Grain Rough Rice.
Mixed Rough Rice.
Rough rice shall meet the following general requirements/limits as determined using the relevant standards listed in Clause 2. Rough rice
Rough rice shall be in form of well-filled seeds of uniform colour representative of the declared variety.
Rough rice for human consumption shall be graded into three grades on the basis of the tolerable limits established in Table 1 which shall be additional to the general requirements set out in this standard.
3Shall be rough rice which do not fall within the requirements of Grades 1, 2, and 3 of this standard but are not rejected rough rice.
Note: For Tanzania and Burundi this requirement shall not apply.
This comprises rough rice which has objectionable odour, off flavour, living insects or which do not possess the quality characteristics specified in Table 1. It cannot satisfy the conditions of ungraded rough rice and shall be graded as reject rough rice and shall be regarded as unfit for human consumption.

Rough rice shall comply with those maximum limits for heavy metals established by the Codex Alimentarius Commission for this commodity.
Rough rice shall comply with those maximum pesticide residue limits established by the Codex Alimentarius Commission for this commodity
Note: where the use of certain pesticides is prohibited by some Partner States, then it shall be notified to all Partner States accordingly.

In particular, total aflatoxin levels in rough rice for human consumption shall not exceed 10 µg/kg (ppb) with B1 not exceeding 5 µg/kg (ppb) when tested according to ISO 16050.
4Rough rice shall be produced, prepared and handled in accordance with the provisions of appropriate sections of EAS 39
