Tragic farm deaths in Poland highlight the need for safety

In a week of worldwide disasters, from Gaza to Ukraine, the deaths of seven people on a pig farm in Poland should not be overlooked.

The seven, including four people from the same family, are reported to have been overcome by poisonous slurry gases when a woman worker accidentally drove a tractor onto a slurry tank, which gave way.

Others who tried to rescue her also died in the incident, near Karczowka, a village in western Poland. Officials said the victims include a father, his two sons and a daughter-in-law.
