A California avocado company is voluntarily recalling shipments that were sent to six states after officials said the fruit might be contaminated with a bacterium that can cause health risks.

The recalled California-grown avocados were packed at a facility in California and distributed in that state, Arizona, Florida, New Hampshire, North Carolina and Wisconsin, the company, Henry Avocado Corporation, said in a statement on Saturday.

It was not immediately clear how many avocados were affected, but the company said that all shipments from its packing facility were subject to the recall. In an article posted on the company’s website about its move into the facility last year, officials said it would give them the ability to ripen more than two million cartons of avocados each year.

From November 2017 to October 2018, the last period for which data is available, 338 million pounds of California avocados were harvested in the state, according to the California Avocado Commission.
