《5月17日 巴黎》國際度量衡局（International Bureau of Weights & Measures, BIPM）發布局長 Dr Martin Milton針對今年(2023)世界計量日主題「計量支持全球糧食系統(Measurements supporting global food system)」的談話影片。特將影片與其原文/中文翻譯附錄如下，以饗讀者。

 附錄 (原文/中文翻譯)

Food is a major concern for every one of us. Providing access to safe and affordable food remains one of the major challenges for governments worldwide. This is also the goal of farmers and food producers who trade products through distributors and retailers to consumers at international, national and local levels. In 2021, this trade was worth 22 trillion USD and accounted for approximately 20 % of all global trade.

To trade internationally and to access markets for high-value products, producers must be able to show that they meet food standards. Additionally, governments need to ensure safety and fair trade especially in local markets for food. All of this is supported by reliable measurements of the quantity and quality of the primary and processed food products involved.

Our focus for World Metrology Day in 2023 is on the many measurement challenges that must be addressed to make the global food system work. For example:

• the quantity of food bought and sold is measured according to its mass or volume. These measurements range from the large volumes of grain and wheat traded internationally down to rapid online weighing measurements to ensure pre-packaged goods are labelled correctly;
• the effective storage and packaging of food depends on the accurate control of the temperature and humidity of its storage environment;
• the quality and authenticity of food is determined by measuring its chemical composition. This requires measurements to ensure that it contains the stated levels of vitamins through to measurements of its isotopic composition to validate the origin of high-value foods such as honey or wine; and
• the safety of food is ensured by careful measurement to detect the presence of chemical contamination such as pesticide residues and heavy metals or biological contamination such as mycotoxins.

It is now recognised that the depletion of natural resources and the impact of climate change pose major challenges to the global food system such that the goal of a world with zero hunger and universal access to clean water was included amongst the Sustainable Development Goals set by the United Nations.

We again look forward to celebrating World Metrology Day with our stakeholders around the world.

糧食是人人關心的議題。 提供安全和負擔得起的糧食是世界各國政府的重要挑戰，同時也是農民和食物生產商的目標，他們透過經銷商和零售商將食物銷售至全球各地的消費者。2021年的糧食貿易額達到 22 兆美元，約佔全球貿易總額的20%。

為行銷全球及高端市場，生產商必須證明他們的產品(糧食)符合食品標準。除此，政府也需要確保安全和公平貿易，尤其是當地市場的交易。這一切都依靠可信賴的量測數量和質量，含括初級食品和加工食品。

我們將 2023 年世界計量日的重點放在使全球糧食系統運轉必須解決的許多量測挑戰上。 例如：

• 糧食的質量與容積，計量範圍從國際貿易大量穀物交易到一般市場的在線秤量，皆需有計量標準來確保商品包裝之正確標示。
• 糧食包裝與儲存環境需有準確的溫度和濕度控制。
• 食品的質量和成份是透過量測分析其化學成分來確定的。如量測蜂蜜、葡萄酒等食物的維生素比例及同位素組成，藉由計量以確保其含有規範標準的營養素。
• 通過精密量測得以檢測農藥殘留和重金屬等化學污染物或黴菌毒素等生物污染物，確保食品安全。

我們意識到自然資源的枯竭和氣候變化已對全球糧食系統構成重大威脅，因此，聯合國將零飢餓和潔淨水源列入永續發展目標。

我們期待與世界各地的相關人員共同慶祝世界計量日。
