A video has emerged appearing to show a woman licking the top of an ice cream tub before placing it back in a supermarket freezer.
The video was posted to Twitter by Optimus Primal showing the woman, who is yet to be named, tucking into a Blue Bell branded tub who then returns the item to its place.
The US ice cream company, based in Texas, says it's working with authorities and that the incident would "not be tolerated".
"We want to thank our consumers for alerting us to this incident this past weekend of a video posted to social media showing a Blue Bell item being tampered with," the company said on its website.

"We take this issue very seriously and are currently working with law enforcement, retail partners and social media platforms.
"Food safety is a top priority, and we work hard to provide a safe product and maintain the highest level of confidence from our consumers."
It's unclear where the video was taken and inquiries are continuing.
