I’ve always told my daughters, whenever someone says, “trust me,” immediately do not trust them.

Trust is earned by actions, not words.

Amidst reports that Listeria-contaminated Blue Bell ice cream is selling well on Craiglist and other Internet markets, U.S. Food and Drug Administration types said they were never told of repeated findings of Listeria at a Blue Bell Creameries facility before an outbreak linked to the ice cream turned deadly.

Results of a Food and Drug Administration investigation released last week showed the company had found 17 positive samples of Listeria on surfaces and floors in its Oklahoma plant dating back to 2013. The FDA said Friday that it “was not aware of these findings” before doing its own inspection this year.

“Although Blue Bell’s testing did identify Listeria, the company did not further identify the strain to determine if it was pathogenic,” FDA spokeswoman Lauren Sucher said.

Which is why all test results should be public.
