A hechsher is a certification that indicates a food product is prepared in accordance with Jewish law (kashrut). It is typically represented by a symbol or logo on packaging, assuring consumers that the product meets the dietary standards required for kosher consumption. The hechsher is issued by a reliable rabbinical authority or organization, which inspects the production process and ingredients. Different hechsherim may have varying levels of stringency, so consumers often choose products based on their personal observance and beliefs regarding kashrut practices.
