Forty-five years ago, mercury contaminated meat and eggs in Czechoslovakia, but the communist regime concealed the incident from the public due to fear of scandal. The government also suppressed information about infectious diseases, maintaining silence through state-controlled media. Today, transparency is prioritized, with media involvement and inter-agency cooperation playing crucial roles in food safety. The State Health Institute is among the organizations monitoring mercury levels, particularly in fish and fish products. Currently, mercury levels in food remain at or near the lowest acceptable limits. This represents a significant shift from the previous practice of concealment and highlights improved safety standards.
