【正文】 necessary for an importation activity to ‘release’ (that is, introduce) pathogenic agents into a particular environment, and estimating the probability of that plete process occurring, either qualitatively (in words) or quantitatively (as a numerical estimate). The release assessment describes the probability of the ‘release’ of each of the potential hazards (the pathogenic agents) under each specified set of conditions with respect to amounts and timing, and how these might change as a result of various actions, events or measures. Examples of the kind of inputs that may be required in the release assessment are: Biological factors species, age and breed of animals agent predilection sites vaccination, testing, treatment and quarantine. Country factors incidence/prevalence evaluation of Veterinary Services, surveillance and control programmes and zoning and partmentalisation systems of the exporting country. Commodity factors quantity of modity to be imported ease of contamination effect of processing effect of storage and transport. If the release assessment demonstrates no significant risk, the risk assessment does not need to continue. Exposure assessment Exposure assessment consists of describing the biological pathway(s) necessary for exposure of animals and humans in the importing country to the hazards (in this case the pathogenic agents) released from a given risk source, and estimating the probability of the exposure(s) occurring, either qualitatively (in words) or quantitatively (as a numerical estimate). The probability of exposure to the identified hazards is estimated for specified exposure conditions with respect to amounts, timing, frequency, duration of exposure, routes of exposure (. ingestion, inhalation, or insect bite), and the number, species and other characteristics of the animal and human populations exposed. Examples of the kind of inputs that may be required in the exposure assessment are: Biological factors properties of the agent. Country factors presence of potential vectors human and animal demographics customs and cultural practices geographical and environmental characteristics. Commodity factors quantity of modity to be imported intended use of the imported animals or products disposal practices. If the exposure assessment demonstrates no significant risk, the risk assessment may conclude at this step. Consequence assessment Consequence assessment consists of describing the relationship between specified exposures to a biological agent and the consequences of those exposures. A causal process should exist by which exposures produce adverse health or environmental consequences, which may in turn lead to socioeconomic consequences. The consequence assessment describes the potential consequences of a given exposure and estimates the probability of them occurring. This estimate may be either qualitative (in words) or quantitative (a numerical estimate). Examples of consequences include: Direct consequences animal infection, disease and production losses public health consequences. Indirect consequences surveillance and control costs pensation costs potential trade losses adverse consequences to the environment. 第四章 風(fēng)險(xiǎn)管理 第十九條 當(dāng)境外發(fā)生重大疫情和有毒有害物質(zhì)污染事件時(shí)，國(guó)家質(zhì)檢總局根據(jù)我國(guó)進(jìn)出境動(dòng)植物檢疫法律法規(guī)，并參照國(guó)際標(biāo)準(zhǔn)、準(zhǔn)則和建議，采取應(yīng)急措施，禁止從發(fā)生國(guó)家或者地區(qū)輸入相關(guān)動(dòng)物、動(dòng)物產(chǎn)品、動(dòng)物遺傳物質(zhì)、動(dòng)物源性飼料、生物制品和動(dòng)物病理材料。 第二十條 根據(jù)風(fēng)險(xiǎn)評(píng)估的結(jié)果，確定與我國(guó)適當(dāng)保
