11、tional Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has be

12、en established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical stan

13、dardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for

14、voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

16、e fever, foot and mouth disease (FMD), Newcastle disease and avian influenza (AI) are becoming increasingly more frequent and geographically widespread. These epidemics spread quickly across country borders due to rapid exchange of people, animals and products between countries. Epidemics threaten t

17、he welfare of human beings through secondary infection on other livestock, economic loss and public health. Preventing the spread of epidemics to other areas where livestock are raised is the priority. However, when this fails and the epidemic has spread, rapid and effective action should be taken t

18、o prevent the further spread of infection. Slaughter followed by disposal of infected livestock is an essential means of preventing the spread of the epidemic.Disposal methods for slaughtered livestock include: incineration, rendering, composting and burial. Burial is a method that has long been use

19、d, as it is relatively economical and does not require specialized techniques or equipment. However, it does have the potential to contaminate the receiving environment. Leachate from the buried animal carcass can pollute the soil and the surrounding waters (groundwater and surface water), and the g

20、as caused by the decomposition of the carcass produces foul. Despite such drawbacks, burial continues to be used widely, because it can limit the spread of an epidemic when massive amount of carcasses must be disposed rapidly. The objectives of this International Standard are to curtail the spread o

21、f the disease, to destroy the causative agents, and to dispose of the carcasses by burial.ISO 28901:2011(E) ISO 2011 All rights reserved vBS ISO 28901:2011BS ISO 28901:2011INTERNATIONAL STANDARD ISO 28901:2011(E)Soil quality Guidance for burial of animal carcasses to prevent epidemics1 ScopeThis Int

35、asses, and dis pose of excreta and other obnoxious material.Four factors will constrain the work:a) The need for urgency arises because there will be a multiplicity of pathways by which the causative agents can be transmitted from live or dead animals within the area affected to animals in remote lo

36、cations. The causative agent can be spread by birds, other wildlife, or transported by wind or wind-blown dust, and water. All of these mechanisms are difficult to control.b) In an attempt to arrest some of these pathways, the site shall be quarantined, with movements of people and other animals ons

37、ite and offsite being minimized, controlled and disinfected.c) As a consequence, the work shall be constrained by what is in hand or can readily be obtained.d) Further adaptation should be made to suit local ground conditions.The number of animals involved shall also be considered.NOTE For example,

38、in one small outbreak in 2007, over 350 cattle were slaughtered on one day, and 800 pigs and 50 more cattle were slaughtered on the following day.5 Planning of burial programme5.1 Time of burialCarcasses should be buried as soon as possible after their death. However, it should be noted that postmor

39、tem livestock will gas up and increase volume by up to half. Therefore, if they are placed in a burial pit too soon and covered over, the carcasses will subsequently rapidly degas, causing large voids to form and causing cracking of cover material. Therefore, either the stock should not be covered i

40、mmediately or the carcasses should be pierced to prevent them gassing up.Once buried, decomposition and degradation processes will intensify after 24 h to 72 h (depending on the ambient temperature), which will pose additional threats to health and the environment.Each country may have a specified t

41、ime frame within which carcasses shall be buried.5.2 Consideration of diseases and kind of animal carcasses infectedWhen livestock are sufficiently believed to be infected by an epidemic, owners of livestock in the area where the epidemic has spread or may spread can be ordered to immediately eradic

42、ate the livestock. Livestock eradication requirements can differ on a national scale, depending on the form of the epidemic. Diseases listed by the World Organisation for Animal Health (OIE) are given in Annex B.5.2.1 Consideration of volume of carcasses to be buriedIt might be necessary to bury the

43、 following:a) carcasses and parts thereof;b) excreta, including: urine, dung, sweat, saliva, snot (nasal mucus), tears, earwax, milk, semen, “afterbirth”;c) miscellaneous droppings, for example: hair, scurf, skin, blood;ISO 28901:2011(E) ISO 2011 All rights reserved 3BS ISO 28901:2011d) infected str

44、aw, bedding mixed with dung, farmyard manure (if infected), etc.Depending on the disease, some or perhaps all of these can transmit viable causative agents.Burial volume is generally determined by the livestocks species and size. If the burial volume is uncertain, it should be assumed that no more t

45、han 300 kg of carcass per 1 m3will be permitted. Table 1 gives an indication of average livestock weight.Table 1 Average livestock weightType Kind of animal WeightkgBeef cattle Cows and bulls 550Feeder cattle 450Replacement heifers 360Calves 135Dairy cattle Cows and bulls 600Replacement heifers 450C

47、 handling, the infected livestock should be buried at the site where they are found.The principal advantages of burial over incineration are that burial tools are simple, and movements off the site where infected animal carcasses occur are minimized.When a suitable location for burial is not availab

48、le on the farm, burial would have to be off the farm.If the carcasses are buried on the farm, continuing maintenance and monitoring of the burial area are required (in relation to an existing national specification, if available); see also Clause 8. This area should be taken out of production.NOTE T

49、he presence of the pit, even if landscaped, can reduce the value of the land.5.3.2 Methods of burialThe following methods of burial are distinguished.Simple burial: The carcasses are laid into a pit and soil is placed directly on top of them, perhaps with the addition of some quicklime. In this method, earth-dwelling worms, insects, and bacteria have direct access to the carcasses and assist in their disintegration. However, large volumes of obnoxious effluent are to be expected, and the causative agents are likely
