As “Mark Levine” has posted, “SSK aka Kosher Technical Konsultants out of Philly, is NOT accepted by any reputable agency.” A few months ago, I personally did research into SSK. I have no reason to think that Rabbi Silver is not a wonderful individual. What I did find out is that he has not lived in Philly for years. Which raises the question, why someone would purport to be somewhere that he realistically is not? Is there something to hide? As mentioned by others, I also was informed by major kashrus organizations that this hechsher is not accepted by reputable agencies.
