Are Kosher Symbols Reliable?

Four well known and reliable Kosher Symbols in the USA

Trying to keep kosher can be difficult. There are so many different food products and ingredients available, and it can be hard to know which ones are acceptable for a kosher diet. Even food that doesn’t have any obviously non-kosher ingredients can be rendered taboo if it’s processed on the same line as non-kosher items or comes into contact with non-kosher utensils. Thankfully, there are kosher symbols that can help make the task of keeping kosher a little bit easier. But with thousands of different symbols out there, which ones can you trust? Here are five well known North American reliable kosher symbols.
