FDA Sampling Frozen Berries for Harmful Viruses

January 22, 2020

As of September 30, 2019, the FDA has tested 339 domestic samples and
473 import samples of frozen berries.

Of the frozen berries sampled, the FDA found genetic material from
hepatitis A virus in five samples and genetic material from norovirus
in eight samples, using multiple-laboratory validated RT-qPCR methods
for the detection of hepatitis A virus and norovirus viral sequences
in soft fruit. These 13 samples were then further tested by another
method called Sanger sequencing to see if the viral material could be
further characterized by examining a separate, distinct section of the
viral genomes. Nine of the 13 samples could be further characterized
using this technique. When the FDA detected genetic material from
hepatitis A virus or norovirus in a sample, the agency notified the
firm of the finding(s) and worked with them to take appropriate action
to protect the public health.
