    BOSTON (WCVB) — A Hopedale, Massachusetts, man and former Boston Children’s Hospital nurse is set to be arraigned next week after prosecutors accused him of sexually assaulting two teenage boys in his care, according to Suffolk District Attorney Kevin Hayden.

John Tam, 33, was indicted by a grand jury earlier this month on four counts of indecent assault and battery on a person 14 years or older and four counts of indecent assault and battery on a patient by a healthcare provider.

He is scheduled to be arraigned in Suffolk Superior Court on Monday.

According to investigators, one alleged incident dates to Sept. 19, 2022, when a 15-year-old boy underwent chest surgery at Boston Children’s Hospital, 300 Longwood Ave. Prosecutors say the teen had been given anesthesia and later awoke to find his nurse, identified as Tam, inappropriately touching his genitals.

A second alleged assault was reported on Jan. 2, 2025, when Boston police were called to the hospital after another teen said he had been sexually assaulted by Tam after surgery while recovering from anesthesia.

Investigators allege Tam told the victim’s mother to move her car to the entrance for discharge, then dressed the patient, took him to the first floor, and brought him into a single-stall bathroom even though the teen did not need to use the restroom. Prosecutors say Tam then sexually assaulted the victim for about eight minutes, including fondling his genitals and offering to pull up pornographic material on his phone.

Authorities said the victim’s mother alerted hospital staff immediately after realizing something was wrong. Investigators also said security footage allegedly shows Tam wheeling the patient into a bathroom and leaving about nine minutes later.

The indictment involves two teenage boys, but investigators say they are concerned the alleged assaults may not be isolated incidents.

“We are concerned that these may not be isolated incidents, and we want to assure parents that any information they provide will be thoroughly and sensitively investigated,” Hayden said. 

Hayden urged parents whose children may have encountered Tam at Boston Children’s Hospital or at his prior workplaces, including Beth Israel Deaconess Medical Center, UMass Memorial Medical Center Worcester campus and UMass Memorial Medical Center Marlborough campus, to contact authorities if they have any suspicions that their children may have been assaulted.

“Because this matter is the subject of pending litigation, we cannot comment,” a UMass Memorial spokesperson said in a statement.

“At Boston Children’s Hospital, our patients’ and their families’ safety and well-being are our utmost priority and we continue to cooperate with the investigation and prosecution,” Boston Children’s Hospital said in a statement.

A Beth Israel Deaconess Medical Center spokesperson released the following statement:

“We do not comment on ongoing legal matters. This individual worked briefly for BIDMC several years ago, in 2019 and 2020. They do not presently work at BIDMC. BIDMC does not perform pediatric surgery and is not licensed for inpatient pediatric care.”

Kathryn Robb, an advocate for children with the nonprofit Enough Abuse, emphasized the prevalence of child sexual abuse in the United States.

“We have an epidemic of child sex abuse in this country where about 1 in 5 children will be sexually assaulted before their 18th birthday,” Robb said.

Robb is advocating for stronger laws to protect children, including mandatory education and training programs at institutions that serve minors.

“Creating education programs, training programs, mandated by law at these institutions that serve children,” she said.

Some meat products with jalapeños may be linked to salmonella outbreak, USDA says

▶ Watch Video: How to limit your exposure to foodborne illnesses, according to an infectious disease specialist Federal officials on Saturday issued a public health alert for meat products containing jalapeños that may be linked to a salmonella outbreak that has sickened hundreds of people across at least 27 states. The U.S. Department of Agriculture's Food Safety and Inspection Service, or FSIS, said the alert applied to red meat and poultry products containing jalapeños that may be contaminated with salmonella. The USDA said that it learned of the issue when it discovered that multiple establishments that are regulated by FSIS had received a recalled ingredient. It released a list of 18 recalled products that are impacted by the alert. Those included the brands Taylor Farms, Ready Meals, Meal Simple, Higher Harvest and Deli Kitchen. The agency said in a statement that it "expects additional downstream products will be identified as this ingredient recall progresses."The first illnesses in the salmonella outbreak were reported in mid-June, according to the U.S. Food and Drug Administration, and were linked to jalapeño peppers grown in Sinaloa, Mexico, and distributed by Coast Citrus Distributors to wholesalers, restaurants and food service companies. The USDA said that so far "there have been no confirmed reports of illness" from products regulated by FSIS that contain jalapeños that were sourced from Sinaloa. As of Aug. 5, the outbreak had sickened at least 345 people, 36 of whom have been hospitalized, the U.S. Centers for Disease Control and Prevention reports. Minnesota was particularly hard hit, with at least 110 cases confirmed in the state. Data compiled by the CDC found that of 191 patients that were interviewed about their illness, 93% reported eating at a Mexican-stye restaurant before falling sick, including popular chains Chipotle and Qdoba. Chipotle announced this week that it had pulled jalapeños from some of its restaurants, and Qdoba followed suit soon after. On Saturday, grocery giant Albertsons announced that it was voluntarily recalling four items containing jalapenos — salsa and corn salad — supplied by Taylor Farms. CBS News has reached out to Taylor Farms for comment. Symptoms of salmonella can include diarrhea, fever and abdominal cramps. Those symptoms can begin anywhere from six hours to six days after consuming the bacteria, the CDC says.
