Research – Pathogenic Staphylococcus aureus in hospital food samples; prevalence and antimicrobial resistance properties

Wiley Online Staph

Abstract

The present investigation was done to study the prevalence and antibiotic resistance properties of S. aureus strains isolated from hospitals foods. Four‐hundred and fifty‐seven raw and cooked hospital food samples were collected and transferred to laboratory. Samples were cultured and S. aureus isolates were subjected to disk diffusion method. Forty‐seven out of 457 (10.28%) hospital food samples harbored S. aureus. Chicken meat (27.02%), meat barbecue (16.12%) and salad (7.14%) were the most commonly contaminated samples. S. aureus strains exhibited the highest levels of resistance against penicillin (70.21%), tetracycline (59.57%) and trimethoprim‐sulfamethoxazole (51.06%). Prevalence of resistance against ceftaroline (25.53%) and chloramphenicol (27.65%) were low. High prevalence of S. aureus in raw and cooked hospital food samples showed insufficiency of cooking time and temperature in the kitchens of hospitals as well as lack of personal hygiene. Further studies are essential to assess other microbiological and epidemiological aspects of the S. aureus.

Practical applications

Due to the general weakness of hospitalized patients, hospital food samples should have a high microbial quality. Staphylococcus aureus is common foodborne bacteria with an emergence of antibiotic resistance. This study emphasizes the importance of multidrug resistant S. aureus in hospital food sample. Results represented that hospital food samples may act as a reservoir of S. aureus with ability to transfer antibiotic resistance.

USA – Canada, Washington state probe Salmonella cases tied to cucumbers

CIDRAP 

 

Cucumbers are suspected in Salmonella illnesses reported from Canada and Washington state, though it’s not clear yet if the events are related.

The Public Health Agency of Canada (PHAC) said federal and provincial health officials are investigating 45 lab-confirmed Salmonella Infantis infections in five provinces, most of them in the west: British Colombia, Alberta, Saskatchewan, Manitoba, and Quebec. The patient from Quebec had traveled to British Columbia, which has reported 37 of the cases.

According to an Oct 19 notice, PHAC said the outbreak’s source hasn’t been identified, but many of the people who got sick reported eating cucumbers before their illnesses began. Symptom-onset dates range from the middle of June through late September, and so far, nine people have been hospitalized. No deaths have been reported.

A food safety investigation by the Canadian Food Inspection Agency is under way, and if contaminated food products are found, it will take further steps, which would include recalling the product. So far, there are no recalls associated with the outbreak.

Meanwhile, the Washington State Department of Health (WSDH) said it is working with state, local, and federal health partners to investigate six Salmonella infections in residents from five counties: King, Snohomish, Thurston, Yakima, and Pierce. The same (unspecified) strain of Salmonella is responsible for all of the illnesses, and the last confirmed patient’s symptoms began on Sep 15.

Five of the six people bought and ate English cucumbers from various Costco stores in Washington. According to the WSDH, the cucumbers linked to the infections were sold in three-packs of individually wrapped cucumbers. It urges consumers who bought English cucumbers at Costco between Aug 18 and Sep 10 and still have them in their refrigerators to throw them away.

USA -McCain Foods USA expands recall to all products it makes at Colton, CA facility – Salmonella – Listeria monocytogenes

Food Safety News

Details about the recalls by national retailers and multiple manufacturers over common ingredients remain murky but  McCain Foods USA Inc. is now recalling all products from its Colton, CA facility 60 miles east of Los Angeles, which produces fire roasted caramelized or sauteed frozen fruit and vegetable products.  Ingredients from that California facility may be the cause of the multiple recalls in recent days.

In a news release, McCain said it “identified a potential health risk” to its product line at Colton.  But the company was not exact about its problem at Colton, when it originated, volume of production involved or where it was distributed.

More than 755.5 tons of additional meat and poultry products were recalled by a half-dozen companies over the weekend for containing various vegetables apparently supplied by McCain over potential contamination from both Salmonella and Listeria pathogens.

Information – How Temperature Influences Legionella Growth

Legionella Control Legionella_Plate_01

In this review the experts at Legionella Control International look at how water temperatures influence legionella growth and how this information can be used to control the risks from the bacteria.

Under certain circumstances Legionella bacteria can lead to serious illness and fatalities in humans. Since Legionella bacteria can exist in man-made water systems, it is imperative to ensure the water is stored, maintained and distributed at temperatures that do not encourage the growth and spread of the bacteria.

There are three temperature ranges that have an influence on the growth and proliferation of Legionella bacteria. Read at the link below.
