In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good. 

Example Input: I'm a little shocked that this so-called health food product is made from Chinese grown ingredients.  I'd be curious to see what the carbon footprint of each bite is.  Also keep in mind that Chinese ingredients and products have been found to have all kinds of contaminants such as lead in toys and melamine in milk and other exported food products. All the ingredients in this snack are widely available in the United States.  Why not support products and companies who source locally and consider our own economy before we sell out for a slightly cheaper price?  Your purchasing choice does make a difference.  Let's stop expecting corporations and governments to take care of our safety and economy.  They never will.  We can change the way these companies do business for the benefit of our long term health and economical well-being. Make purchase decisions wisely.

Example Input: My dog became very ill (vomiting, diarrhea, excruciating pain) in mid-Oct and spent three days at the Emergency Vet - and cost us $3500! They ruled out a bunch of things and were only able to say that he might have Irritable Bowel Disease but the biopsy to find out for certain would cost us an additional $1800. He did recover (without the test) and came home and is on a special gastrointestinal diet now. However, I have to say that I had a large bag of these in my cupboard when he became ill and used them regularly as the treat of choice to get him in his crate. I can't say for sure that these were the cause but I won't be buying ANY dog food products (treats or otherwise) that are made in China. Treats made in the USA only for us!!
