There is some debate over whether or not bingo markers are toxic. However, the vast majority of scientists believe that the markers are not particularly harmful.
In fact, some people even believe that bingo markers can be beneficial because they help keep players focused and motivated.
Some people do worry about the potential for bingo markers to be toxic if they are ingested in large doses. However, the levels of toxicity that could occur from playing with bingo markers are likely much lower than the levels of toxicity that could occur from ingesting other types of toxins.
In fact, even if a person ingested a large amount of a bingo marker, it is unlikely that they would experience any serious health consequences.
