Coronavirus and food safety: DO NOT SHARE FOOD WITH OTHERS!

"It is crucial, even within families, to make sure not to share food that someone else directly bit into or drank," says Dr. Felicia Wu, the John A. Hannah Distinguished Professor, Department of Food Science and Human Nutrition, Department of Agricultural, Food, and Resource Economics at Michigan State University. 


Dr. Wu also currently serves as an expert adviser to the Joint Food and Agriculture Organization (FAO)/WHO Expert Committee on Food Additives of the United Nations.


 “Even though COVID-19 (specifically SARS-CoV-2) is not typically airborne (therefore, you don’t have to worry about contracting it from breathing air unless an infected person coughed near you), it is droplet-borne. That is why someone infected with this virus and coughing, sneezing, or spitting close to you would increase your risk of becoming infected. For that same reason, although it sounds a bit disgusting to discuss, people transmit their saliva onto the food they eat and the beverages they drink, which may subsequently contain SARS-CoV-2 if they are infected. Therefore, no sharing even with your own family.”



Dr. Wu was also able to provide some very important expert insight on what may be common questions that are being asked in the community.

 

 

TAKEOUT: Is takeout safe during the coronavirus outbreak? What about raw foods and salads? And, what are some steps you can take to make takeout safer?


Dr. Wu: Yes, it is generally safe to order and eat takeout food, if you can trust the overall safety practices of the restaurant. Cooked food is usually free of pathogenic microbes; the only danger is if food workers somehow coughed or otherwise transmitted infected droplets to the food after it was cooked and before it was packaged for takeout. There is some risk to raw, uncooked foods if anywhere along the handling chain, an individual who was infected with SARS-CoV-2 coughed or otherwise transmitted droplets onto the food. If there are concerns regarding food delivery, customers can inform the restaurant that they would prefer to have the delivery person put the food on their porch and ring the doorbell.


GROCERY STORES: There are lots of people in stores and hands touching food. How can you keep produce safe? Does washing help? And how long can the virus last on a package or on a piece of produce?


Dr. Wu: This is definitely a problem and has always been a problem (we’re only becoming more concerned about it now). It is entirely plausible for a sick person to rub their nose or their mouth, or cough or sneeze into their hands, and then use those same hands to touch fruit, vegetables, etc. in the grocery stores. I would recommend washing all produce intended for raw (uncooked) consumption at home (and wash your hands, too!) with soap and water. There is a considerable amount of uncertainty with how long coronavirus can survive on different surfaces, so absolutely, it is a good idea to disinfect jars or cans of food before putting them away at home. Again, wash your hands afterwards.

Ask the expert: The constituencies who will determine Michigan’s election results

When it comes to how Michigan has voted in modern presidential elections, a majority of voters have voted for the Democratic nominee for president. In recent years, however, Michigan has become more competitive as a key swing state. In 2016, former President Donald Trump won by just over 10,000 voters and in 2020 President Joe Biden won by just over 150,000 voters. After Vice President Kamala Harris replaced President Biden as the Democratic nominee, she has had a thin lead over Trump and, now, many pundits are saying Michigan is a toss-up. For Harris to win the presidency, she likely must carry Michigan and that includes needed margins with key voter groups such as young voters, as well as Arab American and Black voters. Nazita Lajevardi is an associate professor in the Department of Political Science in the College of Social Science. She is an expert in American politics, and her work focuses mainly on issues related to race and ethnic politics, political behavior, voting rights and immigration. Here, she answers questions on key groups of voters and the issues they care about that could determine who wins Michigan — and likely who will win the presidency. Responses and excerpts are from an article published in Brookings. Where does the election stand in the final days? Since Biden stepped down at the end of July, Harris has enjoyed a steady — albeit at times uncomfortably thin — lead over Trump in Michigan. However, polling from the end of September onward suggests that Harris comfortably winning the state on Nov. 5 is not a foregone conclusion. With just three weeks left to go in the 2024 presidential race, the polling website FiveThirtyEight indicates that as of Oct. 24, 2024, Kamala Harris is ahead of Donald Trump in Michigan by only 0.6 points — 47.6 compared to 47.0. This narrowing of the race appears to be closing the gap that Harris gained over Trump in August. Diving deeper into specific polls feeding into these estimates, it becomes clear that while Harris maintained a solid and consistent lead over Trump by between one and up to eight percentage points in the middle half of September, polls from the third week of September onward have either had Trump leading the state, Harris winning the state by a slim margin, or the two of them being evenly split. What issues do Michigan voters care about? A September 2024 New York Times/Siena College poll found that the three issues Michigan voters cared most about were the economy (24%), abortion (17%) and immigration (14%). Trump, for one, has campaigned heavily in recent weeks about two of these three issues. For instance, he has appealed heavily to Michiganders whose jobs were lost to globalization and automation by promising to revive the American car industry and bring back car factories that have closed in recent years. Groups like Duty to America are highlighting Trump’s strengths on illegal immigration by airing ads across Michigan arguing that it has hurt white people who have been “left behind.” And, while Harris, on the other hand, has great strengths on abortion rights, success in the 2022 elections in amending the state constitution to secure the right to abortion and other reproductive health services may have reduced abortion’s importance as a central voting issue in the state. What impact will Black voters have on Michigan’s result? Among Black voters, experts have identified an enthusiasm gap between those who are part of the “Black leadership class” and deeply connected to the Democratic Party and those Black Michiganders without those same connections, who are more working class, poorer, more fatigued, less interested, and therefore more susceptible to sitting out elections. Many Black voters are also deeply concerned about the economy, and as Michigan State University political scientist Meghan Wilson has noted, Harris could attract Black business owners and holders of student debt by discussing plans to infuse capital into small businesses. The Harris campaign appears to agree. Recently, Harris not only unveiled economic proposals appealing to Black voters but also traveled to Detroit to participate in a radio town hall with Charlamagne tha God, whose program The Breakfast Club has a nationwide audience, much of whom is Black. But attention should be paid to one particular effort to stifle Black turnout. Recently, it was revealed that Tom Barrett, a GOP candidate for the U.S. House, ran a newspaper advertisement in the Black-owned newspaper Michigan Bulletin that incorrectly informed the readership, most of whom are Black, to vote on Nov. 6, when Election Day is Nov. 5. What impact will Arab American voters have on Michigan’s result? Harris is in a deeply precarious position vis-à-vis Michigan’s Muslim and Middle East/North Africa, or MENA, electorates. Without a doubt, these groups will have an outsized impact in deciding how Michigan’s 15 electoral college votes will be cast. According to political scientist Youssef Chouhoud, Michigan is home to more than 200,000 Muslim registered voters. Over the past year, Muslims’ support for the Democratic Party has plummeted. In a recent poll fielded between Aug. 25 and Aug. 27, the Council on American Islamic Relations found that Jill Stein is leading Muslim voters in Michigan; 40% of Muslims surveyed in that poll supported Stein, 18% supported Trump and only 12% supported Harris. And, as Harris’ support for Israel remains steadfast while Israel continues its assaults on Gaza and now Lebanon, she has arguably alienated these voters who could have been a reliable source of electoral support for her. What will the role of youth voters be in Michigan’s outcome? Young voters in Michigan present a potential stream of untapped support for the Democratic Party. Though young voters have historically turned out at lower rates than older Americans, young voters in Michigan stand out from their peers. Fifty-four percent of Michiganders 18 to 29 years old voted in the 2020 election, a 20% increase from 2016. In the 2022 midterms, when young voters aged 18 to 29 in Michigan recorded the highest voter turnout in all the country, they demonstrated how impactful their votes were in enshrining abortion and voting rights in the state constitution. That year, about 75% of students who were registered voters at the University of Michigan and Michigan State University cast ballots. This year, however, how successful Harris has been in activating the youth vote remains to be seen. Certainly, young Michiganders are more enthusiastic about her candidacy than they were Biden’s, but recent analyses by Michigan State University political scientist Corwin Smidt indicate that so far youth turnout in Michigan’s November 2024 election lags behind their 2020 levels. What’s more, young voters were a key part of the “uncommitted” coalition who sent a strong message to then presidential nominee Biden over his enabling of the Israeli war in Gaza during the February 2024 primary election. But Harris is making strides to connect with young voters by establishing offices at campuses across the state. Importantly, young voters could not only shape the outcome of the presidential election, but also the partisan balance in Congress, given that young voters at Michigan State University will have the opportunity to cast a ballot in the race for Michigan’s 7th Congressional District, which is among the 26 toss-up districts in the country.

Ask the Expert: Understand the latest on COVID-19 and mpox

As the university physician at Michigan State, Michael Brown advises the president and other leaders on major health policy or programs that impact life on campus or education abroad programs. He is also chair of the Department of Emergency Medicine in the MSU College of Human Medicine. Here, Brown shares the latest guidance about two viruses that are making news — COVID-19 and mpox, which was formerly called monkeypox. Is COVID-19 changing? COVID-19 will be with us for years to come. It seems to come and go in waves and now, it’s surging again across the United States. We’re seeing more cases, but the number of severe cases is much lower than the peaks we saw during the height of the pandemic. This is good news. Just a small fraction of the people who get COVID-19 actually become sick enough to go to the emergency department. We have to keep that in perspective. How can people stay healthy? The virus does mutate — that’s what viruses do — and a couple recent variants have become predominant. Ideally, the next vaccine will target the latest prevalent variants. I expect the Food and Drug Administration to release a new vaccine very soon, and I definitely will be in line to get one when it’s available. In fact, I highly encourage everyone to get a vaccine this fall. The effectiveness peaks about four weeks after you receive it and lasts at least four to six months — maybe longer. The people who are most protected are those who have had a bout of COVID-19, built up their immunity and received a vaccine. This combination is the best protection from getting an illness that’s severe enough to send you to the hospital. What symptoms are associated with this strain of COVID-19? The symptoms are much like what we’ve seen from COVID-19 in the past. It is an upper respiratory illness, so you may have a sore throat, congestion and a cough, but there can be other symptoms like headache. Some people experience nausea, vomiting or diarrhea. Fever and muscle aches are also common. What if someone tests positive for COVID-19? False positives are very rare with COVID-19 tests so if you get a positive result, you should take care of yourself and protect those around you. The Centers for Disease Control and Prevention recommend that you stay home and wear a mask around others. You should also treat your symptoms, stay hydrated and take acetaminophen for fever and muscle aches. After 24 hours of feeling better and being fever-free (with no acetaminophen), you can go out in public. It’s advised that you wear a mask for an additional five days to protect people who are vulnerable. And what about mpox? Mpox is a viral disease largely found in the Democratic Republic of the Congo in Central Africa. The people there are accustomed to living with it. But it mutates, and we have seen a change in the disease patterns in the past few years. One of the new variants is more severe and is now spreading in the Congo region. It has become a critical situation there, but we have not seen the more severe variant here in the United States. Mpox is not as transmissible as COVID-19 because it requires close contact — usually intimate contact or other close physical proximity like sharing a towel. Symptoms include a rash that may start on the face or genital area along with fever and body aches. A vaccine is available, and an experimental drug can be prescribed as treatment. The World Health Organization has asked developed countries like the United States to assist with research to better understand the new variant. Looking to know more - we can help.

Just the facts, please

Fact-checking might be a full-time job this election cycle as pundits, people on social media, news panels and even presidential candidates are weighing in on topics - perhaps before getting all the details or double-checking for the truth. With the recent decision by President Biden to opt off the ballot for this November's election - it ignited a firestorm of opinions on whether it was legal or not. It's why places like PolitiFact reached out to Michigan State University's Brian Kalt to get 'the fact's on just what was legal or not. He added however, the the Supreme Court has the final say if it is contested. Brian Kalt, a Michigan State University law professor, said he couldn’t imagine the Supreme Court would prohibit Democrats from replacing Biden as their presidential nominee. "But who can say?" he added. "The Supreme Court has a habit of exceeding the bounds of my imagination." And, if you are a reporter covering politics, the campaigns and the election this November, then let our experts help with your questions and ensure your coverage is accurate. Brian Kalt is a Professor of Law and a Harold Norris Faculty Scholar at Michigan State University. He is an expert in constitutional law of the presidency, and he’s available to speak with media regarding how the Constitution and laws play a role in elections.
