The Canadian Food Inspection Agency says test samples from meat processed during an inspection at a troubled Alberta beef plant are negative for E. coli.

CFIA spokesman Paul Mayers says the agency is now looking at E. coli control, hygiene, sampling techniques and overall sanitation at the XL Foods plant in Brooks.

He says that review should be finalized on the weekend.

The Public Health Agency of Canada says one more case of E. coli poisoning has been linked to meat from the plant -- bringing the total to 16.

The person from Quebec became ill in September but is recovering.

More than 1,800 beef products that originated at the Brooks plant have been recalled from dozens of retailers in Canada and the U.S. since last month.
