and CO I genetic sequencing, TFDA confirmed that these flyblown-like objects
were flyblown of Lucilia cuprina (Figure 5-7). TFDA assisted Changhwa
health bureaus to clarify the source of contamination and protect food safety by

developing identification approaches for unknown samples.
C. Kaohsiung health bureau and Tainan prosecutor’s office conducted joint
inspection of the manufacturing factories of pork blood cake and found some
suspicious products. TFDA received a total of 6 samples of raw materials and
products for pork DNA identification because the products and samples appeared
to be black and were suspected containing no porcine materials. After analysis
using high resolution GC-MS and tandem UV detector, a suspicious peak was
found in the non-target sample, which had been confirmed as Heme B. Heme
B is a blood matrix, so the samples were sent for HPLC protein identification.

The results showed that all 6 samples contained porcine hemoglobin, proteins
and heme, which indicated that the products are made of porcine materials. Such
testing technology can be used to determine the authenticity of raw materials to
assure the consumers’ right.
