Gregory Stanton, 49, has been sentenced to 10 months in prison as well as being fined £8,000 after filming himself performing the disgusting acts.
In 2016, the worker filmed himself urinating into a bucket before pouring the contents onto a production line.
Shockingly, a month later he also recorded himself urinating directly on to the cereal conveyor belt.
The clips see the man pointing his penis at the conveyor while directing a stream of wee all over the belt.
He then turns the camera around and directs the lens at the Kellogg’s logo pictured on another piece of machinery.
The footage quickly went viral but by the time it emerged, the contaminated products were likely to have already been eaten by customers.
After viewing the clips, Kellogg’s called the police which sparked an investigation that involved the Food and Drug Administration (FDA).
Stanton pleaded guilty in court back in November to tainting consumer products with intent to cause serious injury to the business of any person.
US Attorney D. Michael Dunavant said: “American citizens and consumers rely upon food manufacturers engaged in interstate commerce to provide them with safe and consistent products.
“This defendant betrayed that trust by tampering with and tainting food products.”
A Kellogg’s spokesperson told WMC-TV: “It has been more than two years since this incident came to our attention, and we are pleased that the responsible individual was brought to justice.”
“We want to thank the FDA and US attorney’s office for their commitment.”
It remains unclear what motivated Stanton into urinating on the production line and sharing the videos of the disgusting acts.
WREG-TV reports the company and workers’ union were involved in a labour dispute at the time.
It comes after a “scumbag” filmed himself “peeing on a memorial” to a nine-year-old boy.
Two thugs were filmed “urinating” on a London Underground seat before another passenger sat down.
