Voluntary Recall of Frozen Raspberry Products

November 1, 2019 


Dear DUSD Community, 

The health and safety of our students is our top priority and we are committed to keeping you informed. We received notice today, November 1, 2019, from one of our food vendors, Wawona Foods, on a voluntary recall of frozen raspberry products because they have the potential to be contaminated with the very common foodborne illness, Hepatitis A. 

Once we received the notice, our Child Nutrition Department located and disposed of five cases of the frozen raspberry product. We then contacted the Alameda County Public Health Department on next steps. They let us know they have not identified any cases of Hepatitis A in Alameda County associated with this product at this time.

This does not include any of our elementary schools. Schools possibly affected by this voluntary recall include Dublin High School, Valley High School, Cottonwood Creek School (grades 6-8), Fallon Middle School, and Wells Middle School. 

We use a very small amount of this product to make parfaits by mixing the frozen raspberry product in with other fruits. We have been using this product since August 2019 and make around 200 parfaits a week that are distributed across these five schools. 

About Hepatitis A - Foodborne Illness
Hepatitis A is a vaccine-preventable viral illness that can cause symptoms of fever, headache, fatigue, loss of appetite, nausea, vomiting, diarrhea, abdominal pain, jaundice (yellowing of the skin or eyes), dark urine, or pale stool. Symptoms of Hepatitis A typically occur within 15-50 days after eating or drinking a contaminated product. Unlike Hepatitis B or C, Hepatitis A does not cause chronic disease. Persons who have received 2 doses of the Hepatitis A vaccine are considered immune.

Next Steps for Families

We are asking for your cooperation in following the advice given to us by the Alameda County Public Health Department:

  •  If your student consumed a parfait between September 12, 2019 through October 31, 2019, monitor your child for symptoms. If you think your child is having symptoms of Hepatitis A, please consult with their healthcare provider. Based on these potential exposure dates, symptoms of Hepatitis A could develop through December 20, 2019.
  • Check your child’s vaccination status for Hepatitis A. It is recommended that children 12 months through 18 years of age be given the two dose vaccine series.
