BRAZOS COUNTY, Texas -

According to a press release Monday by the Brazos County Health Department, the investigation of 10 cases of Shiga-toxin producing Escherichia coli has concluded.

Five of those cases have been confirmed as E. coli.

Five other cases, which were investigated due to the symptoms, will not be listed as confirmed because only symptoms occurred during the investigation timeframe.

According to the investigation, the source of the E. coli has been linked to ground beef from a local restaurant, however, it is not known whether the cause was due to improper temperature, improper cooking, or cross-contamination.

This was an isolated incident and is not an on-going threat to public health.

Throughout the investigation the restaurant was fully cooperative.

There have been control measures implemented to prevent further cases, including mandatory glove use by employees and continuous monitoring by BCHD.

BCHD will host a press conference on Tuesday, May 21 at 1:00 p.m. in the health department classroom.
