One of my best friends had a farm in Eastern Washington. In addition to the veggies, etc., they normally raised about 100 head of cattle and would keep a 1/2 side or so for themselves. She said she would not buy meat anywhere but Costco. I have a friend that works at Costco and they told me that they only buy the best (I forget what it is - Select?). All the meat I have bought from Costco is very good. I always get the spiral cut, honey-baked Kirkland Signature hams for Christmas Eve dinner.
BTW - I love to make things fresh, but I must say that the mashed potatoes (Yukon golds) that they have in their deli (Costco makes them, not pre-packaged) are very good and a huge time saver. I’ve used those some times when I’m doing a big dinner and have little time - everyone loves them. No peeling, boiling, mashing, etc. - just nuke :-)
What? Mashed potatoes that taste good? Yukon Golds? No peeling? Oh, SC, I had no idea they sold those!
I rarely look at prepared foods like that, but I will watch for them next trip to Costco!
The only meat I have purchased at Costco that I didn’t care for was the Australian lamb. It must be raised in barns and corn fed. I used to buy the New Zealand lamb (before my daughter raised sheep) and assumed Australian would be the same. Nope.
Other than that - all Costco meat has been excellent.
