`This apple was produced using a relatively new method of genetic engineering, known as RNA interference. This technology uses RNA to silence a target gene, but mounting evidence has shown that meddling with the genes could have unintended effects within the plant and also on organisms that eat the plant. The particular gene targeted by this technology allows the apples to be sliced without turning brown, which could mislead consumers into thinking they are eating fresh apples when they might be eating apples on the verge of rotting. Browning is an important indicator to consumers in determining the freshness of an apple or apple slice.
