Semen was found in a yogurt sample that was given to a woman in a supermarket, US police have confirmed.

The 28-year-old female shopper had tried the free yoghurt sample in Sunflower Farmer’s Market in Albuquerque, New Mexico, when it was given to her by a male clerk in the dairy section.

She said it tasted “gross and disgusting,” and “it tasted like semen”.

In a handwritten statement, the woman wrote, “I spit it out on the floor many times cuz I was upset”.

The woman had a word with the manager of the store, who told her it was Greek yogurt:

“People love it, it has a lot of protein in it,” she was told.

When the woman later told her boyfriend of the earlier events, they both returned to the shop and decided to call in the cops, giving them the leftovers of the sample.

The customer explained that she found it odd that the clerk had “just come with one sample just for me,” and “he was so pushy to tell me how to taste it.”

Tests have now shown that the sample did contain semen and saliva.

The 31-year-old employee, Anthony Garcia is suspected of contaminating the yogurt, and blood and DNA samples have been collected to see if he can be linked to the crime.

When police later spoke to the suspect he was described as “extremely nervous”, telling police that he had binned the other samples after the female shopper’s earlier complaint.

Police also discovered that Garcia was wanted for a previous conviction, including criminal sexual activity with a minor, and Garcia was arrested on the spot.
