CDC Investing Millions in Enhanced Antibiotic Resistance Testing

The Centers for Disease Control and Prevention (CDC) is investing $77 million in efforts to track and fight antibiotic resistance. The money is going to public health departments in all 50 states and Puerto Rico. The hope is that officials will develop new ways to combat antibiotic resistant bacteria in food, healthcare facilities, and communities. The funding will open a new surveillance center for TB. And the overall focus is on enhancing testing capabilities in the agency's regional antibiotic resistance labs. Seven regional labs that are part of the CDC's Antibiotic Resistance Lab Network will be able to expand antibiotic susceptibility testing for Candida auras. This bacteria has shown resistance to all three classes of drugs that are usually used to fight these infections. … [Read more...]

Oysters and Vibriosis

The Centers for Disease Control and Prevention (CDC) is issuing information about the risk of contracting a Vibrio infection when consuming raw oysters. Summer is prime oyster season. And it's the time of year when most illnesses from raw oysters occur. In fact, a man in Washington state recently contracted a Vibrio infection when he purchased a live fish from a fish tank. One of the most common illnesses linked to raw oysters is vibriosis. This infection is caused by the Vibrio vulnificus or the Vibrio parahaemolyticus bacteria that occur naturally in seawater. Oysters are filter eaters, which means they draw in seawater and filter out the food and bacteria. The bacteria then become concentrated in the oysters flesh. Most Vibrio infections are caused by Vibrio parahaemolyticus. … [Read more...]

Deadly Multistate Salmonella Kiambu Outbreak Linked to Papayas

A multistate outbreak of Salmonella Kiambu infections linked to yellow Maradol papayas has sickened 47 people in 12 states, according to the Centers for Disease Control and Prevention. Maryland officials warned consumers about this potential outbreak with a recall of Caribeña’s brand yellow Maradol papayas this week. The CDC's announcement did not mention any brand of papaya in particular, but did state that "Salmonella Kiambu infections are linked to yellow Maradol Papayas en Español." The case count by state is: Iowa (1), Kentucky (1), Louisiana (1), Maryland (5), Massachusetts (1), Minnesota (1), New Jersey (12), New York (13), Pennsylvania (4), Texas (1), Utah (1), and Virginia (6). Twelve ill persons have been hospitalized, and one death has been reported in New York … [Read more...]

Salmonella Outbreak Linked to Teaching and Clinical Labs

In a rather unusual outbreak, public health officials have identified 24 people in 16 states sickened with Salmonella Typhimurium infections linked to teaching and clinical laboratories. Six of those sickened have been hospitalized. No deaths have been reported. This is the same strain that was associated with infections linked to microbiology lab exposure in 2011 and 2014. This is a public health problem and a reminder that bacteria used in microbiology laboratories can sicken people who work in those labs. [Editor's note: The first time I was in a microbiology lab the professor warned us against eating or drinking in the room and also walked us through safety steps, including frequent hand washing and the use of gloves, lab coats, and goggles.] In addition, people who live with … [Read more...]

Trichinellosis Outbreaks in Alaska Linked to Walrus Meat

Many older people can recall their moms cooking pork to well done (or more) because of the fear of trichinellosis. Pigs used to be fed scraps, or they foraged for their food, so their meat was infected with a microscopic parasite called Trichinella. A few thousand cases occur every year around the world. In the United States, the USDA has reduced the recommended internal temperature for pork to 145°F from 160°F, since pork is no longer likely to be contaminated with the parasite. Cases have greatly declined in this country since the 1950s. But the disease is making a comeback among people who eat walrus meat. Two trichinellosis outbreaks in Alaska linked to walrus meat are the subject of a report in the CDC's Morbidity and Mortality Weekly Report for July 7, 2017. This illness … [Read more...]

Salmonella Outbreak in 2016 Linked to Hot Peppers

A multistate outbreak of Salmonella Anatum infections that were linked to imported hot peppers appears in the The Morbidity and Mortality Weekly Report for June 30, 2017. This is the first government report on this outbreak. Thirty two people in nine states were sickened in this outbreak that happened during the summer of 2016. The CDC and FDA did not publish anything about this outbreak at the time because government officials couldn't find a source for the outbreak, specifically a common source for the peppers, so consumers couldn't take steps to protect themselves. Epidemiologic, lab, and traceback evidence found that fresh hot peppers were the likely source, but "a single pepper type or source farm could not be identified." Fresh hot peppers and other produce have been the … [Read more...]

FDA Releases List of Facilities that Served Hepatitis A Positive Tuna

The FDA has released a list of facilities that served frozen raw ahi tuna cubes that were recalled for possible hepatitis A contamination. In their investigation report they have added a table that includes the names and addresses of the 31 restaurants and stores that sold the product in California, Texas, and Oklahoma. This product was recalled twice. The first recall was in Hawaii only. The product is imported raw frozen ahi tuna cubes sourced from PT Deho Canning Co. in Indonesia, sold under Tropic Fish with lot codes 609149 and 609187. The current recall, which was issued on May 18, 2017 [editor's note: we cannot find this recall on any FDA page], is for frozen yellowfin tuna steaks from Sustainable Seafood Company and yellowfin tuna cubes from Santa Cruz Seafood. This recall by … [Read more...]

Raw Milk Products Cause 840 Times More Illness Than Pasteurized Milk

According to the Center for Disease Control and Prevention's (CDC) Emerging Infectious Diseases report for June 2017, unpasteurized milk products cause 840 times more illness and 45 times more hospitalizations than pasteurized milk products. Only about 3.2% of the population consume raw milk, and 1.6% of consumers eat raw cheese, but those products cause 96% of the illnesses linked to contaminated dairy products in this country. The number of states that allow raw milk sales increased to 30 in 2011, from 21 in 2004. Consumption of unpasteurized dairy products is becoming more popular, and this raises public health concerns. The bacteria in these products that have caused serious illness and death include E. coli, Salmonella, Campylobacter, and Listeria monocytogenes. This increase … [Read more...]

CDC Study Looks at Restaurant Food Allergy Practices

As part of the Morbidity and Mortality Weekly Report for the week of April 21, 2017, the Centers for Disease Control and Prevention (CDC) has published a study about food allergy practices in restaurants across the country. Food allergies affect about 15,000,000 people in this country and cause about 30,000 emergency department visits and 150 to 200 deaths every year. Almost half of the fatal food allergy reactions over a 13 year period were caused by food from a restaurant or other food service establishment. The report found that fewer than half of members of the restaurant staffs surveyed in 278 restaurants had received training on food allergies. And although most restaurants list ingredients or recipes for some menu items, few have separate equipment or areas that are designed … [Read more...]

CDC Releases Data on Foodborne Illnesses and CIDTs 2013 – 2016

In the latest issue of CDC's Morbidity and Mortality Weekly Report, a report studied the incidence and trends of infections of foodborne pathogens from 2013 - 2016. The report also looked at the effect of the increasing use of culture-independent diagnostic tests (CIDTs) on pathogen surveillance. Overall, the 2016 incidence of confirmed Campylobacter infections was lower in the United States, but incidences of confirmed Shiga toxin-producing E. coli (STEC), Yersinia, and Cryptosporidium infections were higher. But the report states that culture-independent diagnostics tests (CIDTs) are complicating this data, because testing for pathogens may be occurring more frequently using this method.  In 2016, FoodNet, the CDC's Foodborne Diseases Active Surveillance Network, identified … [Read more...]
