新冠肺炎疫情持續，不少市民保持衛生意識，食飯用餐時都使用公筷防止交叉感染。早前央視就與專家進行不用公筷的實測，發現不使用公筷情况下，餸菜菌落總數比起使用公筷相差高達909倍，筷子可助細菌傳播致交叉污染結果相當驚人！
中央電視台和國家副食品質量監督檢驗中心的專家合作，實測使用公筷和不使用公筷時餸菜的菌落總數，以涼拌黃瓜、乾鍋茶樹菇和香辣牛蛙3道菜做測試，將餸菜以無菌方式分為3份，4名研究員先以公筷進食第一組菜；再於不使用公筷的情況下進食第二組菜；最後每碟菜抽取25克作樣本，進行菌落總數研究。
樣本餸菜存放於攝氏36度的環境經過48小時後，結果發現涼拌黃瓜的不使用公筷樣本比使用公筷樣本的菌落總數多出1.3倍；而乾鍋茶樹菇兩組樣本數據相差高達909倍；而香辣牛蛙兩組樣本數據則相差44倍。研究結果如下：
研究專家指出，用餐時不使用公筷，人體攜帶的細菌會隨筷子傳播到餸菜，導致餸菜之間出現交叉污染，當夾涼拌食物後又夾熱食，便會將涼拌食物的細菌轉移到熱食上，因此市民一定要使用公筷，避免肉眼無法看見的細菌互相傳播。
其實早於香港新冠肺炎疫情爆發初期，張竹君亦呼籲市民在家中使用公筷，減低家庭之間的交叉感染。面對疫情大家記緊要保持衞生意識，減低疾病傳播風險。
