La Crosse County Extension Specialist Heather Quackenboss says beware of recipes you see online, on Facebook, or on TikTok -- "dry canning" or "upside down canning" can cause food poisoning! She says there haven't been reports yet on canning supply shortages like we saw during the height of the pandemic. You can use plastic mayo jars or old pickle jars to freeze produce, but not to can for shelf stability. Make sure you get your pressure canner checked out. Anyone can call the La Crosse County Extension for help with that.
