JACKSONVILLE, N.C. (WITN) – Several students at two Eastern Carolina elementary schools became sick after drinking milk at their cafeterias, school officials say.

Onslow County Schools’ Brent Anderson said that the milk was not spoiled or out of date and had been stored at an appropriate temperature.

Anderson said that an inspection revealed that milk from one particular lot had a peculiar odor and that milk distribution was stopped out of an abundance of caution.

The Onslow County Health Department is investigating.

“Parents are asked that if their child consumed milk at school today and shows any signs of gastro-intestinal distress, to please contact their medical provider immediately,” Anderson says.

The school system did not share what two schools the children fell ill at.
