Is there a way to tell if a berry is contaminated?
assistant
Yes, there are several ways to test for contamination. The most common methods include visual inspection, chemical testing, and DNA analysis. Visual inspection involves looking at the color, size, shape, texture, and smell of the berry. Chemical tests involve checking for the presence of certain chemicals or toxins in the berry. Finally, DNA analysis can be used to determine whether the berry has been genetically modified.
