WeightWatchers is shaking up its leadership. WW International on Friday announced that CEO Sima Sistani would leave her role effective immediately. Tara Comonte, a WeightWatchers board member and former Shake Shack executive, was made interim chief executive.

The New York-based company didn’t reveal the reasons behind the abrupt move. It noted that Comonte would step into the CEO role at a time when the company is “focused on improving its operational and financial performance.” Sistani joined WeightWatchers as CEO more than two years ago. During her tenure, she led the company’s moves into the prescription drug weight-loss business.

Boar’s Head faces legal scrutiny over deadly deli meat listeria outbreak, USDA says

Boar’s Head, the deli meat company at the center of a deadly listeria food poisoning outbreak, is being scrutinized by law enforcement officials, the U.S. Agriculture Department disclosed in response to government records requests.

U.S. Agriculture Department officials disclosed the action in response to requests for government records. Officials refused to give The Associated Press documents about inspections and enforcement at a now-closed plant in Virginia or inspections from eight other Boar’s Head factories. The outbreak has killed 10 people and sickened more than 50 in 19 states and precipitated several lawsuits.

Previously released records revealed problems including mold, insects, dripping water and meat and fat residue on walls, floors and equipment dating back at least two years. Boar’s Head earlier recalled more than 7 million pounds of deli meat distributed to stores across the country.
