Meat Contamination in Dumplings

Abstract

Accurate labelling of meat products is essential for public health. Mislabeled or cross contaminated meat products endanger the health of people with allergies. This study aims to evaluate the accuracy of meatballs in dumplings by using polymerase chain reaction (PCR), DNA separation, and gel electrophoresis. 30 samples were tested with 5 replicates for each of the 6 dumpling types (vegetarian, chicken, lamb, pork, beef + pork, and lamb + pork samples). In addition, a negative control containing distilled water was included to ensure reliability. The result of our study shows the pork samples did not contain pork DNA and goat DNA was detected in five of the six lamb meatball samples but lamb specifically refers to sheep. These findings suggest that contamination or mislabeling occurred in processing dumplings. The vegan samples confirmed the authenticity of its label because no meat DNA was detected in all vegan meatballs. Our results emphasize the importance of strict quality regulations in the food industry to ensure accurate product labelling and prevent cross-contamination during the process.
