A coalition of state attorneys general has opened an investigation into OpenAI, according to people familiar with the matter, the latest in a series of legal actions by states directed at artificial intelligence companies.

OpenAI was served Friday with a subpoena seeking documents related to a range of its activities and impact on users, including advertising, user engagement and retention, handling of consumer data and health data, activities related to minors and seniors, deep learning models, model sycophancy and company policies, some of the people said. The subpoena, viewed by The Wall Street Journal, was sent by New York’s attorney general.

Federal health officials are urging parents to immediately stop using a popular organic infant formula after three babies were hospitalized with botulism in a multistate outbreak linked to the product.

The Centers for Disease Control and Prevention said all three infants consumed Nara Organics Whole Milk Organic Infant Formula before becoming ill.

The babies, who ranged in age from 2 to 5 months, were hospitalized and treated with BabyBIG, the FDA-approved treatment for infant botulism.

The cases were reported in California, Pennsylvania and Washington, according to the CDC.

Testing of opened and unopened formula samples is underway, with results expected in the coming weeks.

Officials said opened cans may be retained and stored separately if an infant develops symptoms, as state health departments may request samples for testing.

According to the CDC, infant botulism occurs when spores from Clostridium botulinum bacteria enter a baby’s digestive tract and produce a dangerous toxin.

Early symptoms can include constipation, difficulty feeding, a weak or altered cry and loss of head control.

Parents should seek immediate medical attention if an infant who consumed the recalled formula develops symptoms including poor feeding, difficulty swallowing, decreased facial expression or loss of head control, health officials said.
