On August 23, Resolution No. 23 of the Ministry of Health was published in the Official Gazette, amending Decree No. 106 of 1997, of the same authority, which establishes the Mineral Water Regulations.
In this sense, the purpose of this amendment is to make compatible the provisions of Article 160 of the Food Sanitary Regulation with the Mineral Water Regulation, by reducing, in the latter instrument, the arsenic limit from 0.05 mg/l to 0.01 mg/l in bottled mineral waters intended for consumption or sale.
Thus, as of this publication, bottled mineral waters intended for consumption or sale must come from natural, officially recognized sources, meet the bacteriological conditions required for drinking water, have a degree of mineralization of less than 1.5 grams per liter and not exceed the limit of 0.01 mg/l of arsenic.
