I needed to know extra about listeria contamination and why it’s harmful. What signs should people look ahead to, and how is the an infection identified and handled? Who is most in danger for extreme sickness, and what meals are most frequently linked to outbreaks like this one? And as we head into the vacation season, what can people do to cut back their probabilities of getting sick from foodborne micro organism?
To assist me with these questions, I turned to NCS wellness skilled Dr. Leana Wen. Wen is an emergency doctor and medical affiliate professor at George Washington University. She beforehand served as Baltimore’s well being commissioner, the place her tasks included overseeing meals security.
NCS: What is listeria, and why is it harmful?
Dr. Leana Wen: Listeria monocytogenes is a kind of micro organism discovered in soil, water and sure meals that may trigger a severe an infection generally known as listeriosis. Unlike many different foodborne pathogens, listeria can develop at fridge temperatures, which suggests it could actually survive and multiply in meals which might be already cooked or saved chilly. It most frequently contaminates ready-to-eat meals resembling deli meats, tender cheeses, smoked fish, unpasteurized dairy merchandise and refrigerated ready meals.
For most healthy adults, a light an infection might trigger solely transient flu-like signs, however for sure people, together with pregnant people, newborns, older adults and these with weakened immune methods, listeriosis might be extreme. It may cause bloodstream infections, meningitis, or being pregnant problems like preterm labor, miscarriage and stillbirth. Listeria an infection is the third main reason behind loss of life from foodborne an infection in the United States, based on the US Centers for Disease Control and Prevention. Each 12 months, about 172 people die from an infection.
NCS: What signs should people look ahead to?
Wen: Symptoms of listeriosis typically begin with fever, chills, muscle aches, nausea or diarrhea. In extra severe instances, the an infection spreads past the intestine and may cause extreme headache, stiff neck, confusion, seizures and whole-body an infection ensuing in organ failure. Pregnant sufferers might expertise solely delicate flu-like signs, however the an infection might be devastating to a growing fetus.
NCS: How is listeria identified and handled?
Wen: Doctors diagnose listeriosis by way of laboratory testing, often by figuring out the micro organism in a blood pattern, spinal fluid or different physique fluid. In delicate instances, remedy is probably not vital past monitoring signs, however in extra extreme instances, antibiotics are required. Pregnant people, newborns, older adults and immunocompromised people could also be hospitalized for nearer monitoring and supportive care. Early prognosis and remedy considerably enhance outcomes.
NCS: What should customers do if they’ve the recalled merchandise at house?
Wen: Anyone who bought the recalled pasta meals should not eat them, even when they appear or odor nice. The micro organism can’t be seen, smelled or tasted. And simply because another person has eaten it and has not gotten sick doesn’t imply that it’s secure for you to eat.
Check your fridge and freezer for any recalled manufacturers or packaging, and both return them to the shop or throw them away in a sealed plastic bag to stop cross-contamination. Wash and sanitize any surfaces, cabinets or containers that will have come into contact with the recalled merchandise. If you or a member of the family has eaten one of many recalled meals and developed signs per listeriosis, contact your well being care supplier.
NCS: As we head into the vacation season, what can people do to cut back their probabilities of getting sick from foodborne micro organism?
Wen: The high-profile outbreaks that make headlines may give the impression that foodborne diseases primarily come from eating places or packaged meals bought in shops. In actuality, solely a small portion of instances are traced to industrial merchandise; most happen in our personal kitchens, the place micro organism and viruses can simply unfold by way of on a regular basis dealing with of meals. Practicing cautious hygiene and secure cooking habits at house is among the only methods to cut back the danger of an infection.
Among all foodborne pathogens, norovirus is the commonest reason behind gastrointestinal sickness in the US. It spreads shortly from individual to individual and by way of contaminated meals, particularly when contaminated people deal with meals earlier than or throughout preparation.
Frequent, thorough handwashing with cleaning soap and water is crucial, particularly earlier than cooking, after utilizing the lavatory and after touching shared surfaces. Anyone with signs resembling nausea, vomiting, diarrhea or abdomen cramps should keep house and keep away from getting ready or serving meals to others till they’ve been symptom-free for at least two days. This applies not solely to norovirus however to different contagious gastrointestinal illnesses as nicely.
Undercooked meat, poultry and seafood are one other main supply of foodborne illness, together with infections from micro organism resembling salmonella, campylobacter and E. coli. Cooking meals to their proper internal temperatures kills these pathogens: Chicken, turkey and different poultry should attain 165 levels Fahrenheit (74 levels Celsius); fish should be cooked to 145 F (63 C); and floor meats resembling beef or pork should attain at least 160 F (71 C). Using a meals thermometer is essentially the most dependable approach to make sure these temperatures are met.
Cross-contamination can be a frequent downside. Cutting boards, knives and plates which have been in contact with uncooked meat, seafood or poultry should by no means be reused for cooked or ready-to-eat meals until they’ve been totally washed in scorching, soapy water. Keeping separate utensils and chopping surfaces for uncooked and cooked meals enormously reduces the danger of spreading micro organism.
Fresh fruits and greens should all the time be washed, even when they’ll be peeled earlier than consuming. Rinsing beneath working water is often enough; keep away from utilizing soaps or family cleaners, which might depart residues which might be unsafe to eat. For agency produce like melons or cucumbers, utilizing a clear brush might help take away dust and micro organism from the floor.
Proper storage is one other key a part of prevention. Perishable meals should be refrigerated inside two hours of cooking — or inside one hour if the air temperature is above 90 F (32 C). Leftovers should be saved in shallow containers in order that they cool shortly, and fridges should be stored at 40 F (4 C) or decrease. Freezers should be set at 0 F (-18 C) or beneath. Food not noted too lengthy supplies supreme circumstances for micro organism resembling listeria and staphylococcus to multiply quickly.
Avoid unpasteurized milk and dairy merchandise, in addition to juices or ciders that haven’t been pasteurized, since these can comprise dangerous micro organism. Pregnant people, older adults and anybody with a weakened immune system should be significantly cautious to keep away from these merchandise, as they carry a better danger of significant sickness.
Finally, take note of native and nationwide well being advisories. Health departments and the CDC ceaselessly problem alerts when contaminated meals are recognized or when outbreaks are detected at native eating places or grocery chains. Following these updates and checking your kitchen for recalled objects might help you act shortly to stop sickness.
