could someone please help me formulate a thesis statement on this topic.
It depends on what you want to say. I believe you should start by writing a sentence about something you read in an article about food safety. Make that sentence the topic sentence for a body paragraph, and build a paragraph after it.
Repeat that process until you have a few paragraphs, and then reread it. Ask yourself, what is my main idea? Put that idea in a sentence and make it the thesis statement at the end of the first paragraph.
If you try to choose a thesis statement BEFORE you read some articles, you will have to SEARCH for articles to support your thesis. Make a thesis based on the articles you want to read... after you read them.
