US Report: Food Poisoning Increasing at a Higher Rate

``For some reason, campylobacter is making people sick with lots of different fingerprints,'' Tauxe said.

As recent illnesses tied to raw turkey, ground beef, cut melon and romaine lettuce suggest, U.S. food poisoning cases don’t appear to be going away anytime soon.

The Centers for Disease Control and Prevention said in a report Thursday that the frequency of several types of food poisoning infections climbed last year, but that the increases could be the result of new diagnostic tools that help identify more cases.

Overall, the agency believes food poisoning rates have remained largely unchanged.

Dr. Robert Tauxe, director of the agency’s foodborne illness division, said the figures show more needs to be done to make food safer. He noted the two most common causes of infection have been longtime problems.

One of the two, salmonella, can come from an array of foods including vegetables, chicken, eggs, beef and pork. The other germ, campylobacter, is commonly tied to chicken. People may not hear as much about it because health officials often can’t group cases into outbreaks. Both bacteria are spread through animal feces.

“For some reason, campylobacter is making people sick with lots of different fingerprints,” Tauxe said.

Obstacles to better understanding

The report is based on monitoring in 10 states, but is seen as an indicator of national trends. It highlights the difficulty in understanding food poisoning when so many cases go unreported, diagnostic methods are inconsistent, and production practices and eating habits are constantly changing.

With chicken, for instance, companies have brought down salmonella rates in raw whole carcasses since the government began publishing test results of individual plants. But the U.S. Department of Agriculture only recently began posting similar data for raw chicken parts like breasts and legs, which Americans have gravitated toward over the years.

Last year, the agency said 22 percent of production plants did not meet its standard for limiting salmonella in chicken parts. The USDA said in a statement that it’s working to improve its approach to fighting bacteria, including with the publication of such data.

Despite such efforts, salmonella and campylobacter are allowed in raw poultry sold in supermarkets, noted Tony Corbo of Food and Water Watch, an advocacy group that supports stricter food safety regulations. It’s why health experts advise people to properly handle and cook poultry.

“There is very little the USDA can do besides posting the report card on salmonella,” he said.

The National Chicken Council says the industry has been working to bring down contamination rates, including through germ-killing solutions sprayed on raw chicken during processing, improved sanitation and increased use of vaccines. But the group says the bacteria are endemic in chickens and that eliminating them is difficult.

The CDC report also notes produce is a major source of food poisoning, citing recent E. coli outbreaks tied to romaine lettuce. It said outbreaks tied to produce also contributed to a big jump in infections from a parasite called cyclospora.

The Food and Drug Administration, which oversees the safety of fruits and vegetables, said in a statement that a recently developed test is helping it detect the parasite in produce. The agency is also implementing new regulations for produce, though food safety experts note the inherent risk with fruits and vegetables that are grown in open fields and eaten raw.

The CDC said is still working to confirm how much increases in food poisoning cases can be chalked up to new diagnostic methods. It noted some results of a newer, faster test could be false positives. (VOA)

This Class of Antibiotics Can Treat Dementia

Antibiotics to treat early dementia show promise

Researchers have found that a class of antibiotics called “Aminoglycosides” could be a promising treatment for early onset dementia.

Frontotemporal dementia, is the most common type of early onset dementia, typically begins between ages 40 and 65 and affects the frontal and temporal lobes of the brain, which leads to behaviour changes, difficulty speaking and writing and memory deterioration.

According to the study, published in the journal “Human Molecular Genetics”, a subgroup of patients with frontotemporal dementia have a specific genetic mutation that prevents brain cells from making a protein called progranulin.

Although progranulin is not widely understood, its absence is linked to the disease.

The researchers from University of Kentucky in US, discovered that after aminoglycoside antibiotics were added to neuronal cells with this mutation, the cells started making the full-length progranulin protein by skipping the mutation.

“These patients” brain cells have a mutation that prevents progranulin from being made. The team found that by adding a small antibiotic molecule to the cells, they could ‘trick’ the cellular machinery into making it,” said study co-author Matthew Gentry from the University of Kentucky.

The researchers found two specific aminoglycoside antibiotics – Gentamicin and G418 – were both effective in fixing the mutation and making the functional progranulin protein.

After adding Gentamicin or G418 molecules to the affected cells, the progranulin protein level was recovered up to about 50 to 60 per cent.

These results could be promising to drug development. Currently, there are no effective therapies for any type of dementia, the researchers said.

After this pre-clinical proof of concept study, the next step is to study the antibiotics’ effects on mice with the mutation that causes frontotemporal dementia, they added.

Another focus is to possibly develop new compounds from Gentamicin and G418 that could be safer and more effective.

“If we can get the right resources and physician to work with, we could potentially repurpose this drug,” Zhu added.

This is an early stage of the study, but it provides an important proof of concept that these aminoglycoside antibiotics or their derivatives can be a therapeutic avenue for frontotemporal dementia,” Zhu added. (IANS)
