[2023年8月25日]
今日有市民發現,市面上再度牽起「盲搶鹽」熱潮。因應日本方今日起開始排放核污水,有人士相信核廢水排放將影響日本出口海產等食物。縱使坊間說法眾說紛紜,但有市民則往各超市搶購據稱可解輻射含碘的食鹽。記者晚上前往超市觀察,貨架上放置的食鹽已一掃而空,但仍有數箱未拆箱食鹽。店方表示,店舖食鹽存貨暫時仍然充足,呼籲市民勿太過憂慮。
「盲搶鹽」熱潮源於有消息指出,含有碘的食鹽可解除身體輻射,但專家指出,必須消耗 3.5 磅的碘鹽才能獲得單片碘化鉀中所含的 130 毫克碘,以用於輻射緊急情況。專家表示,一次吃過多鹽並不健康。而且,一個健康的人,長期進食太多或每日累積過量碘鹽,有可能會導致高血壓、動脈硬化、冠狀動脈心臟病、中風,甚至是胃癌。專家呼籲,不建議大量攝取鹽分。
另外,截至今日(八月二十五日)中午,食物環境衞生署轄下食物安全中心(食安中心)已對138個進口日本「水產及其製品、海藻及海鹽」的食物樣本作輻射水平檢測,未有發現輻射水平超出安全標準,同時,漁農自然護理署已對50個本地漁產品樣本作輻射水平檢測,全部樣本檢測合格。香港天文台亦已加強監測本港水域的環境輻射水平。至目前為止,並沒有發現異常情況。
特區政府表示,本港食鹽供應穩定及存貨充足,儲存量足夠全港市民約一個月用。市民不用擔心供應,更無需要儲存食鹽。根據政府統計處資料,本港食鹽主要來源地是中國內地、馬來西亞及澳洲,而日本食鹽只佔整體供應不足1%。特區政府限制日本10都縣水產品進口絕對不會影響本港食鹽供應。
食物安全中心(食安中心)發言人指出:「並沒有科學證據顯示進食碘含量豐富的食物和碘鹽,能夠有效預防輻射對身體造成的損害。相反,過量攝入碘及鈉(鹽)會有損健康,特別是本身患有高血壓、心臟病或腎病的人士。故此呼籲市民不要購買和進食過量食鹽。」食安中心迅速派員巡查零售點,特區政府亦已就本港食鹽供應情況聯絡各大型超級市場(超市)。本港食鹽供應穩定及存貨充足,部分超市貨架上食鹽缺貨的原因只是未及安排人手作即時補充,並非出現缺貨的情況,相關超市會積極跟進及盡快補充貨架上的食鹽,市民不用擔心,更無需要儲存食鹽。
食安中心為了讓市民及業界了解進食碘含量豐富的食物如碘鹽不能作為預防輻射影響的措施,中心已透過不同渠道提供有關資訊,包括今天登載的社交平台帖文、早前發報的網上刊物及專題網頁。
As at noon today (August 25), the Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department has conducted tests on radiological level of 138 food samples imported from Japan, which were of the "aquatic products, seaweeds and sea salt" category. No sample was found to have exceeded the safety limit. In parallel, the Agriculture, Fisheries and Conservation Department (AFCD) has also tested 50 samples of local catch for radiological tests. Hong Kong Observatory (HKO) has also enhanced the environmental monitoring of the local waters. No anomaly was detected so far.
The HKSAR Government indicated today (August 25) that the supply of edible salt in Hong Kong remains stable, with stock sufficient for local consumption for around one month. Members of public need not worry about the supply or stockpile edible salt.
A Centre for Food Safety (CFS) spokesman pointed out that "there is no scientific evidence suggesting that intake of iodine-rich food and iodised salt will prevent the physical harm brought about by radiation. In contrary, excessive intake of iodine and sodium (salt) is harmful, particularly to persons who suffer from hypertension, heart diseases or kidney diseases. Therefore, we appeal to members of the public to refrain from purchasing and eating excessive amount of edible salt."
The staff of CFS has quickly surveyed the retails points. The HKSAR Government also contacted major supermarkets and noted that the supply of salt remains steady and stock remains sufficient. Some of the shelves for salt were not timely replenished due to operational reasons instead of shortage. Relevant retail outlets will actively follow up and replenish the stock of edible salt as soon as possible. Members of public need not worry about the supply or stockpile edible salt. With the view to enabling a better understanding of the members of public and the trade on the incapability of iodine-rich food like iodised salt in shielding radiation, CFS has provided relevant information via different channels, including publishing posts on social media, previous publications and thematic webpage.
