The US Centers for Disease Control and Prevention (CDC) and Food and Drug Administration (FDA) have launched investigations into separate Salmonella outbreaks involving frozen sprouted beans and pistachio cream.

In a media alert issued today, the CDC said 11 people in 10 states have been sickened by a strain of Salmonella (Anatum) linked to Deep-brand frozen sprouted mat (moth) beans and frozen sprouted moong (mung) beans. Illnesses started on dates ranging from October 22, 2024, to June 24, 2025. Four people have been hospitalized, with no deaths reported. 

The affected states are Connecticut, Florida, Illinois, Massachusetts, Minnesota, New Jersey, Pennsylvania, Tennessee, Virginia, and Washington.

Routine sampling by the FDA in May detected Salmonella in product samples, and whole-genome sequencing (WGS) determined it matched the Salmonella strain causing illness. Yesterday, Chetak LLC Group announced a recall of the sprouted beans, which are sold in retail stores nationwide.

"While the Chetak LLC Group has indicated they have not received reports of illnesses directly, FDA and CDC's investigation has linked these products to illnesses in this outbreak through laboratory and epidemiological evidence," the FDA said in its update.

Pistachio cream outbreak

The CDC, FDA, and state partners are also investigating an outbreak of Salmonella Oranienburg linked to pistachio cream sold in World Market stores.

To date, the outbreak has caused three illnesses in two states—Minnesota and New Jersey—with one hospitalization. Illness-onset dates range from March 10 to May 19. All four people interviewed reported eating pistachio cream, including three at the same restaurant.

World Market initiated a recall of Emek brand Pistachio Cream and Emek Spread Pistachio Cacao Cream with Kadayif on July 14, after testing by the Minnesota Department of Agriculture detected Salmonella in the products. WGS is pending to see if it matches the outbreak strain. 

The CDC says the true number of people affected in the outbreak is likely much higher.

Only 35% to 40% of US pregnant women and parents of young children say they intend to fully vaccinate their child, per survey results from researchers at Emory University and the Centers for Disease Control and Prevention (CDC).

For the two surveys, published as a research letter this week in JAMA Network Open, the investigators recruited 174 pregnant women and 1,765 parents from a nationally representative panel in April 2024 to answer questions about their intent to have their child receive all recommended vaccines by 18 months.

"Many parents in the US choose to delay or refuse vaccines that are recommended for their child from birth to age 18 months," the study authors wrote. "Research is necessary to understand the value of intervening during pregnancy to proactively support parents with vaccination decisions before the birth of the child, as implementation of such interventions will require substantial engagement of health care professionals and entities outside of the pediatric care setting."

Vaccine refusal highest among parents

In total, 37.6% of pregnancies were first pregnancies. About half of respondents held a bachelor's degree or higher (49.4% of pregnant women and 45.1% of parents), and 77.6% and 79.5%, respectively, lived in urban areas.

Given the high decisional uncertainty during pregnancy about vaccinating children after birth, there may be value in intervening during pregnancy to proactively support families with childhood vaccination decisions.

Intent to vaccinate was similar among pregnant women and parents, at 35% to 40%. The proportion of respondents planning to refuse some or all vaccines was lowest among women pregnant for the first time (4%) and highest among parents (33%). Women in their first pregnancy were most uncertain about childhood vaccination (48%), while parents were the least unsure (4%).

"Given the high decisional uncertainty during pregnancy about vaccinating children after birth, there may be value in intervening during pregnancy to proactively support families with childhood vaccination decisions," the researchers wrote. 

"Future interventions should account for differences in uptake of seasonal (ie, COVID-19, influenza) vs routinely recommended vaccines," they added. "Future studies with longitudinal follow-up may shed further light on evolution of vaccination decisions from pregnancy to parenthood, and the effectiveness of intervening proactively during pregnancy."

• Hong Kong's Centre for Health Protection (CHP) yesterday warned about a chikungunya outbreak in China's Guangdong province that has so far sickened at least 478 people. Though no related cases have been reported in Hong Kong, the CHP said it is preparing for imported cases and urged people to eliminate mosquito-breeding sites and take steps to avoid mosquito bites. Guangdong province's outbreak is centered in the Shunde district of Foshan, which is on the Pearl River delta. The outbreak was triggered by imported cases. So far, all illnesses have been mild with symptoms that include fever and joint pain. Hong Kong averaged 11 imported chikungunya cases per year from 2016 to 2019 but has not recorded any since 2020.
• GSK today announced that the US Food and Drug Administration (FDA) has approved a prefilled syringe formulation of its recombinant shingles vaccine (Shingrix). Prefilled syringes make it easier for healthcare providers to immunize, because they don't need to reconstitute separate vials before administration. The existing version of the vaccine contains two vials—a lyophilized (powdered) antigen and a liquid adjuvant. Consistent with the earlier version, the vaccine is approved for adults ages 50 and older and those ages 18 and older who are at increased risk for shingles, which is caused by reactivation of varicella-zoster virus, the same one that causes chickenpox. Two doses are needed to complete the vaccine series.
• The US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) this week confirmed 10 more H5N1 avian flu detections in wild and captive mammals, including two with recent sample collection dates—from a harbor seal in Lincoln County, Maine, and a domestic cat in Multnomah County, Oregon. The others were seven skunks from four Texas counties that have sample collection dates in February and March and a harbor seal from Suffolk County, Massachusetts, that was sampled in February.
