(AP) -- A Food and Drug Administration official says the agency is looking into a produce contamination case linked to a shuttered Texas processing plant and may decide to expand a recall.
Don Kraemer of the FDA's Office of Food Safety said Thursday that a decision on whether to expand the recall would be made once the agency learns more.
Texas health officials shut down the SanGar Produce & Processing Co. plant in San Antonio and ordered a recall of all of the produce that had passed through the plant since January.
The plant is linked to contaminated celery that sickened at least six people this year, four of whom died.
SanGar is questioning the validity of the state's lab results, saying flawed methods were used to collect samples.
