USA – Legionnaires’ Disease Outbreak Linked to Christmas Mountain Resort

Outbreak News Today Legionella_Plate_01

Three people have been diagnosed with Legionnaires’ disease and one person has died following stays at the Christmas Mountain Resort in Wisconsin Dell. At this time, the local health authorities are investigating the outbreak.

As the investigation unfolds, a representative for the resort told the local media that some of their accommodations did indeed have Legionella present. “After testing, we found that the water supply in certain units had been affected and, subsequently, tested positive for the bacteria,” the spokeswoman said. The resort claims to be telling prospective guests about the disease, but thus far denies that the confirmed illnesses occurred on their property – despite the fact that all of those who are ill stayed at the resort within 2 weeks of their illnesses.

USA – New Dates For Implementing Agricultural Water Produce Safety

Food Poisoning Bulletin Eurofins Food Testing UK

FDA’s Commissioner Dr. Scott Gottlieb and Deputy Commissioner Frank Yiannas have addressed advancing new tools and science for produce safety via agricultural water, and have set new dates for implementation. The two E. coli O157:H7 outbreaks that were linked to romaine lettuce in 2018 were allegedly caused by contaminated agricultural water.

Research – Does physical state of farm housing and milking practices affect total bacteria and somatic cell count of cow milk?

Wiley Online

Abstract

The study determined the effect of physical state of farm housing on total bacteria and somatic cell count (SCC) of cow milk. Milk records collected at Dairy Services Zimbabwe were used. Effects of physical state of ceilings, doors, ventilation, walls, drains, fly‐proofs, windows and roof type on total bacterial count (TBC) in milk, and SCC were determined using general linear models procedure. Poor physical state of ceilings, doors and floors in milking parlors, wash rooms and bulk tank rooms result in high TBC and SCC in milk (p < 0.05). Poor ventilation in the bulk tank room results in high TBC in milk (p < 0.05). Floors, doors, and ceilings of milking houses should be kept in sound condition and good repair in order minimize TBC and SCC in raw milk.

Practical applications

Understanding how physical state of farm houses and management practices affect total bacterial count and somatic cell count in fresh milk enables farmers and regulatory agencies to put in corrective action to reduce bacterial contamination of milk at farm level. This helps keep the population of disease causing bacteria in raw milk, which is widely consumed by human beings, as low as possible. It also helps reduce contamination by some resistant bacteria that might survive processing and cause further defects in milk products. The shelf‐life of the milk and its products is, thus, improved. Reducing bacterial and somatic cell count in raw milk also helps the milk producers to score high milk grades on the market and, thus, fetch high prices.

USA – State health department warns against Salmonella when handling baby poultry this spring

The Oakland Press

 

Officials at the Michigan Department of Health and Human Services are asking people to know about the potential for baby poultry to carry Salmonella bacteria.

As spring arrives and chicks and ducklings become available in local feed and agriculture supply stores, officials warn that if proper precautions are not taken, even handling baby birds displayed in stores can cause a Salmonella infection.

“Raising birds for eggs and meat can be fun and educational, but all poultry, even those that appear healthy and clean, have the potential to carry the Salmonella bacteria,” said MDHHS Public Health Veterinarian Dr. Mary Grace Stobierski. “Washing your hands thoroughly before and after handling chicks and other poultry protects both you and your family from the risk of Salmonella, and also helps keep the birds healthy.”
