Authorities have identified a second death that may have been caused by Diamond Shruumz microdosing candies, which are under investigation for causing a nationwide rash of severe illnesses involving seizures, and the need for intubation and intensive care.

In an update on Tuesday, the Food and Drug Administration reported that the total number of illnesses linked to the brand's candies has risen to 74 across 28 states. Of the 74 people sickened, 62 sought medical care, and 38 were admitted to a hospital. There are two potentially associated deaths that are now under investigation. The counts are up from 69 cases and 36 hospitalizations, with one potentially linked death reported in an update last week.

The FDA announced its investigation into Diamond Shruumz products on June 7, when there had been just eight cases reported from four states. The federal investigation—led by the FDA and the Centers for Disease Control and Prevention, with help from America’s Poison Centers and state and local partners—followed warnings from Arizona poison control officials.
