It'southward a busy morning – getting ready, eating breakfast, fixing lunch, checking email, grabbing homework. So you notice something out of place. A carton of milk is sitting on the counter.
We've probably all had this happen and, at that point, three questions run through our minds: How long has the milk been out? Is it withal safe? And who left it out?
Our very own registered dietitian Sarah Downs stepped in to help us find some answers.
Okay, Sarah, bottom line: How long can milk be kept out of the fridge before it starts to spoil?
Sarah Downs, RD: "Milk should never exist left out at room temperature.
Refrigeration is the single well-nigh important cistron in maintaining the safety of milk. Milk should be stored at 40° F or below. If stored above xl° F, milk volition begin to develop signs of spoilage, including sour scent, off-flavor and curdled consistency."
What if you're not sure how long the milk has been left out? Is in that location a way to tell if it's still safe to use?
Sarah Downs, RD:"When in uncertainty, throw it out. The general rule of thumb is to discard any perishables that have been stored above the "Danger Zone" of 40° F for more than than two hours, no affair what their appearance or odor (and never taste the food to try and determine whether it's still safety)."
What about ultra-pasteurized milk?
Sarah Downs, RD: "Ultra-pasteurized milk is heated to 280° F for a minimum of two seconds. This temperature and time combination is much more lethal to bacteria, killing about all of concern in milk. Ultra-pasteurized milk is too packaged under near sterile conditions, which makes recontamination with spoilage bacteria unlikely and rare. The boilerplate shelf-life of ultra-pasteurized milk products is 30 to 90 days when held nether refrigeration, but only until the production is opened. And so it should be consumed within seven to ten days to avoid spoilage."
What'southward different virtually the milk yous see sitting at room temperature on the grocery store shelves?
Sarah Downs, RD:"Shelf stable milk has been ultra-pasteurized (UHT) and is packaged in aseptic cartons. This allows the milk to sit at room temperature in the grocery stores. However, it must exist refrigerated after being opened and consumed inside seven to ten days to maintain quality and food safety."
What advice exercise you have for parents to safely pack milk for their lilliputian ones in a sippy cup or luncheon box?
Sarah Downs, RD:"For parents on the go, I would recommend the post-obit options:
- Pack milk in a luncheon box or cooler with an water ice pack to ensure it stays cool.
- Purchase shelf-safe milk (brand sure it has the UHT label on the package besides!). Also, remember that after this milk is opened it should be treated like regular milk and kept cool at xl° F or cooler.
- Information technology's of import to remember that opened milk, regardless of the type, should never exist left in temperatures above 40° F for more than two hours."
Although we may not figure out who was responsible for leaving the milk on the counter, these guidelines will help the states stay safe and enjoy nutritious milk!
