1. What do these products have in common? They have all been certified kosher by one of the 225 kosher certification agencies in the US.
2. What is kosher? According to Orthodox Union, the world's largest kosher certification agency that certifies 70% of all kosher food, kosher means "fit to eat according to Jewish dietary law." Weird that laundry detergent & disinfectant wipes would need certification, right? 🤔
3. Currently, there are about 1.5 million products that are certified kosher. To obtain certification, manufacturers must contact a Jewish certifying agency and pay a fee for a Rabbi to fly out and inspect the ingredients, equipment, & cooking process to make sure they're kosher.
4. Even equipment like pots & pans must be certified kosher. In all cases, the inspecting agency requires daily, weekly, monthly or yearly inspections, lest the Jewish agency revokes the certification. Consequently, inspection frequency affects the fee food manufacturers must pay
5. In a 1989 NY Times article "What's New in Kosher Foods," Rabbi Harvey Sentor says "the cost depends on the complexity of the product. A food with sensitive ingredients might require more surveillance by a rabbi."
More Rabbi "surveillance" means higher fees for manufacturers
