Working Conditions

My topic is about how the federal government should regulate the working conditions in food factories and why it should regulate the working conditions in food factories. Through the research, I hope to find the causes of what happens that are illegal and/or unsafe for the workers in food factories and what the federal government can legally do to prevent or reduce these activities or conditions. I already have stories that anecdotally say what happens in food factories and explain their causes and results. Despite this I am falling short and need help in finding articles that explain what parts of the federal government are able to regulate the working conditions in food factories and how they are able to regulate it, as well as any loopholes that prevent effective regulation. I am also falling short and need help in finding articles that explain how effective that the current laws are as well as any challenges for current or new laws. These laws can include wage law, immigration law, as well as any other laws relating to employment or the inspection of food. The articles could also be about what the food factories usually do illegally, why they do it, how they get away with it, and how to enforce these laws more effectively or the difficulties that workers might have with enforcing the current laws, such as not knowing about these laws or forgetting, if applicable, that there are anonymous ways to report violations, and how to mitigate this. Basically, I am asking "What hindrances, if any, are there that prevent effective regulation of working conditions in food factories?"
