業(yè)務(wù)環(huán)境和相關(guān)方：第4.1章外部和內(nèi)部事項(xiàng)中對(duì)于系統(tǒng)性地確定和監(jiān)測(cè)商業(yè)環(huán)境有新的規(guī)定，第4.2章相關(guān)方的需求和期望中介紹了可能（潛在）影響管理體系實(shí)現(xiàn)預(yù)期結(jié)果能力的因素的識(shí)別和理解需求。

進(jìn)一步強(qiáng)調(diào)領(lǐng)導(dǎo)作用和管理承諾：第5.1章目前包含了積極參與和對(duì)管理體系的有效性承擔(dān)責(zé)任的新需求。

風(fēng)險(xiǎn)管理：第6.1章要求公司決定、考慮并在必要時(shí)采取行動(dòng)，以解決可能影響（無論正面還是負(fù)面影響）管理體系實(shí)現(xiàn)其預(yù)期結(jié)果的能力的任何風(fēng)險(xiǎn)。

進(jìn)一步側(cè)重于目標(biāo)驅(qū)動(dòng)的改進(jìn)：這些變動(dòng)包含在第6.2章以及第9.1章的績(jī)效評(píng)估中。

與溝通相關(guān)的延伸要求：目前第7.4章對(duì)溝通“機(jī)制”有了更多規(guī)定，包括決定溝通的內(nèi)容、時(shí)間和方式。

對(duì)食品安全文件的要求放寬：該變動(dòng)包含在第 7.5章中，仍然要求有文件化信息。必須對(duì)文件化信息加以控制，確保其受到充分保護(hù)（ref.7.5.3）。刪除了對(duì)文件化程序的明確要求。

PDCA循環(huán): 標(biāo)準(zhǔn)明確了策劃——實(shí)施——檢查——處置（PDCA）循環(huán)，采用兩套并行的獨(dú)立循環(huán)：一套涵蓋了管理體系，另一套涵蓋了HACCP原則。

當(dāng)前范圍特別包含了動(dòng)物食品: 動(dòng)物食品，不用于生產(chǎn)供人類消費(fèi)的食品。飼料僅用于喂養(yǎng)提供食品的動(dòng)物。

一些定義發(fā)生重大變動(dòng): “傷害”被“負(fù)面健康影響”取代，以確保與食品安全危害定義的一致性。用“保障”一詞強(qiáng)調(diào)了消費(fèi)者與食品產(chǎn)品之間的關(guān)系基于食品安全保障。

溝通食品安全方針——第5.2.2章: 對(duì)管理提出了明確要求，便于員工理解食品安全方針。

食品安全管理體系目標(biāo): 第6.2.1章中進(jìn)一步規(guī)定了設(shè)立食品安全管理體系的目標(biāo)，包括諸如“符合客戶要求”、“予以監(jiān)視”和“得到驗(yàn)證”等項(xiàng)目。

控制外部提供的過程、產(chǎn)品或服務(wù)——第7.1.6章: 本條款介紹了產(chǎn)品、過程和服務(wù)（包括外包過程）供應(yīng)商的控制要求，確保就相關(guān)要求開展充分溝通，以滿足食品安全管理體系的要求。

此外，與ISO 22000:2005相比，ISO 22000:2018在涉及HACCP系統(tǒng)方面也有一些關(guān)鍵變動(dòng)。

Food safety management systems -- Requirements for any organization in the food chain

This document specifies requirements for a food safety management system (FSMS) to enable an organization that is directly or indirectly involved in the food chain:

a) to plan, implement, operate, maintain and update a FSMS providing products and services that are safe, in accordance with their intended use;

b) to demonstrate compliance with applicable statutory and regulatory food safety requirements;

c) to evaluate and assess mutually agreed customer food safety requirements and to demonstrate conformity with them;

d) to effectively communicate food safety issues to interested parties within the food chain;

e) to ensure that the organization conforms to its stated food safety policy;

f) to demonstrate conformity to relevant interested parties;

g) to seek certification or registration of its FSMS by an external organization, or make a self-assessment or self-declaration of conformity to this document.

All requirements of this document are generic and are intended to be applicable to all organizations in the food chain, regardless of size and complexity. Organizations that are directly or indirectly involved include, but are not limited to, feed producers, animal food producers, harvesters of wild plants and animals, farmers, producers of ingredients, food manufacturers, retailers, and organizations providing food services, catering services, cleaning and sanitation services, transportation, storage and distribution services, suppliers of equipment, cleaning and disinfectants, packaging materials and other food contact materials.

This document allows any organization, including small and/or less developed organizations (e.g. a small farm, a small packer-distributor, a small retail or food service outlet) to implement externally-developed elements in their FSMS.

Internal and/or external resources can be used to meet the requirements of this document.
