The content of radioactive ceasium in dried and dried skimmed milk from selected daires was double determined. The highest content was found in samples from milk from OSM Siedlce (98 Bq/kg) and skimmed milk from Radzyń Podlaski and Ostrołęka, (the former 90, the latter 62 Bq/kg). The lowest level of radioactive caesium was obserwed in samples from dried milk from Sieradz, Słupsk, Września, Olecko and Elbląg (about or below 10 Bq/kg). Although those levels of contamination with radioceasium didn't exceed values recommended by FAO they were determined as high for year 1987/88 as compared milk datas from previous 1985 year.
