, shares her tips for picking the best pineapple at the grocery store.When it comes to picking a pineapple at the store, Testa's tips center on three things: color, smell, and the spiky leaves on the crown. Pineapples that are more yellow or orange are ripe, while greenish pineapples are unripe. A good pineapple "should smell sweet and fragrant," but will have a fermented or alcohol-like scent if it's going bad, Testa says.

Senior Food Director at Delish,, adds, "A good pineapple should be firm but slightly yielding. If it's rock hard, it's underripe."Testa's favorite tip is one that she learned from her grandmother. "When a pineapple is ripe, the green leaves should pull out easily," she says. "If it is difficult to pull out a leaf, the fruit is likely not sweet." Just know that yanking the leaves out of a pineapple at the store might earn you some dirty looks from fellow shoppers. But in your own home, it's a great trick.

Aside from smell, Testa says there are a couple of things that signal a pineapple is not good. White mold on the bottom center of the pineapple and soft or brown spots on the skin are both signs to skip the fruit.Picking a pineapple is only half the battle. Testa recommends keeping the whole fruit on the counter until it's softened to your liking and then moving it to the fridge until you want to eat it. "Pineapples do not ripen after they are picked.

DULUTH, Minnesota (Reuters) -Smoke from wildfires burning in three Canadian provinces is spreading into the U.S. Upper Midwest, stirring memories of the severe pollution that drifted south from Canada two years ago during that country's worst fire season on record.The particulate matter pollution caused by the smoke is already blowing into Minnesota and neighboring states, posing a health risk to the tens of millions who live in the region. It is expected to make its way to New York and other East Coast cities in less severe levels over the coming days.

"Airborne particulate matter is the most serious environmental health risk we know of," said Doug Brugge, a public health researcher at the University of Connecticut School of Medicine. "It causes cardiovascular, respiratory and neurological harm, and these plumes of smoke are at very high levels compared to what we're usually exposed to in the U.S."Scores of wildfires have swept across Canada since the start of May, forcing thousands of evacuations and disrupting crude oil production in the country. There were more than 200 active fires as of Monday, 106 of which were out of control, according to the Canadian Interagency Forest Fire Centre.
