6. I'm certified in safe food handling

Had to attend courses on the "sex life of pathogens" and take written tests. I have cooked over 100,000 hamburgers and have never, to my knowledge, served product that has made someone sick.

I understand concern about food safety because I have been sick on restaurant food.

At the risk of making your concerns worse I will add: hamburger is the oldest beef in most supermarkets. They take steaks that were thawed and that didn't sell within 2 days and they grind them all together, grade them by fat content and put them back out in fresh packages. Same for boneless skinless chicken -- because the fat (skin) on chicken is the first thing to spoil, they strip it off and rewrap the chicken several times -- while then quartered then skinless, then boneless & skinless -- marking the price per pound up each time.

If you want the freshest meats you should buy whole chicken (or on the bone) and grind your own single-source hamburger from chuck or round.
