Examine contemporary issues related to food safety, including tampering, bioterrorism, and different food safety standards across the globe, and identifying food safety barriers that can cause issues with food safety in a global, interconnected environment.
I suggest that you divide it into sections so that you cover the main topics of: tampering, bioterrorism, differing food safety standards, and finish up by explaining how those issues can cause problems with food safety in a global environment. Basically, you will be writing a paragraph or two on each issue and then finishing up with a few paragraphs that tie them all together and show how those issues impact food safety globally.
