Food Safety Today
Once the food is in your hands, it is up to you to make sure that it remains safe to eat. Your responsibility begins when you buy the food, and ends when all the leftovers are gone. Buy foods that are fresh and have not passed their best-before dates. Wash your hands and food-preparation surfaces often, keep foods safely stored and separated, and cook and chill the food properly.

Clean, Separate, Cook, and Chill
If you follow these four food-handling steps, you will reduce the risk of getting a food-borne illness caused by microbes.
Professionals in the food industry handle the food you buy with care, using various technologies to minimize the risk of contamination. Packaging protects food from contamination and creates a barrier which helps to prevent spoilage. Some farms are bio‑controlled to avoid infection of their livestock — visitors must actually wear bio‑suits in areas housing animals.
The food industry has many ways of processing foods. For example, processors may pasteurize, preserve, irradiate, freeze, can, refrigerate, dehydrate, salt, or pickle foods before sending them to retailers.
Before cheese was pressed into a mold, cheesemakers tested how the curd was forming. This tool was used to draw a sample of unripened cheese from the cheese vat.
Meat inspectors must examine all animal carcasses at an abattoir to ensure that they are safe for human consumption. This hammer, with the inspector's 'signature' 241, was used to assign a grade to a side of beef.
Each farm uses government-regulated ear tags on cattle, so that the animal can be traced back to their farm if a food safety issue should arise in the future.
In Canada, cheese made from unpasteurized milk has to be aged for 60 days (until all the harmful bacteria die), and cannot be sold until then.
