Which of the following is a kosher certification agency?

The correct answer is the Orthodox Union (OU), which is one of the most recognized kosher certification agencies globally. The role of a kosher certification agency is to ensure that food products meet the dietary laws outlined in Jewish law (kashrut). The OU evaluates food products and their manufacturing processes to determine if they comply with these dietary guidelines, granting certification to products that meet the necessary standards. Their symbol, the OU, is widely recognized and trusted by consumers seeking kosher products.

In contrast, the FDA (Food and Drug Administration) and USDA (United States Department of Agriculture) are governmental regulatory agencies focused on food safety and agriculture, but they do not specifically oversee kosher certifications. The CDC (Centers for Disease Control and Prevention) is primarily concerned with public health and disease prevention rather than food certification or dietary laws. Thus, the OU stands out as the certifying body specifically for kosher foods.
