The WHO’s manual on food safety here.
I’ve been out of the loop on this for a while, however— yes, food safety practices differ culturally, but actual regulations are fairly similar. The WTO has recommendations upon which standards for imported food are created, resulting in a lot of uniformity in international food safety guidelines. But! There can be equitablility and equivalence allowances for different practices that achieve the same result. FDA conducts inspections on foreign food manufacturing that allow for these differences.
More countries have implemented HACCP in food industries based on WHO guidelines.
Local differences can still result in products considered safe in one region and not suitable for commercial sale in another. For instance in Canada all commercial eggs have to be refrigerated, in part, because we wash our eggs, which removes the protective cuticle so they’re more prone to becoming contaminated. In other countries it’s against regulation to wash commercial eggs and they can be stored at room temperature. But! It’s a food safety risk to leave a refrigerated egg at room temperature for too long because condensation forms on the shell, creating a favorable environment for bacteria.
Some countries don’t allow certain preservatives, additives or chemicals. Borax and lye are used in traditional recipes and legal in some countries, while being against regulations in others.
However, heavy regulations aren’t just based on risk to the weakest consumer, but on variance in circumstance. Not everyone who handles food is a perfect professional, equipment breaks down, cold trucks can overheat, and plenty of other shit can go wrong in the supply chain. Your food might already be heavily contaminated by the time it reaches you and that can’t always be seen or smelled.
Adhering as well as you can to your local food prep guidelines can be overkill 99/100 times, but that 1/100 can prevent slight discomfort/illness/death. It’s about how much risk you want to take on.
I think they’re referring to cooked food. In that case it’s about the same, cooked carrots left at room temperature will grow bacteria the same as cooked chicken.
