"Everybody got some explaining to do why they giving kids strawberries INFESTED WITH MAGGOTS," one student wrote in a tweet.
Several other students also shared jarring images of the frozen strawberry cups, which the school district said were sourced from a USDA-certified supplier.
"It is a frozen product and we serve it partially thawed/frozen to students. Cy-Fair Nutrition Services does not open the individually packaged strawberries we receive," the district said in a statement. "They are served in the original packaging we receive them in and are opened by the students."
The district will file a complaint with the USDA over the incident.
