I think you realise those are high numbers. The difficulty in interpreting them is that you don't have before and after figures because random testing doesn't tell you all that much. You seem to have caught two high levels, but you don't really know what's going on the rest of the time.
I'd suggest, for a couple of weeks to begin with, doing a structured test. Test first thing in the morning, before you've eaten anything; and then test both immediately before eating and again two hours later. The morning test shows you an overnight fasted reading which also might indicate where your liver is used to your blood glucose being: the morning reading is often high.
If you record the test results and also record what you ate - I mean everything you ate and drank - you should start to see some association between certain foods and subsequent blood glucose rises. Once you have that information, you can take informed decisions about what you do next - cut the food out, eat less, ignore and continue as now. That's your decision but at least you can base it on information rather than guesswork.
