ABSTRACT:

Heightened concerns about wildlife on produce farms and possible introduction of pathogens to the food supply have resulted in required actions following intrusion events. The purpose of this study was to evaluate the survival of Salmonella in feces from cattle and various wild animals (feral pigs, waterfowl, deer, and raccoons) in California, Delaware, Florida, and Ohio. Feces were inoculated with rifampin-resistant Salmonella enterica cocktails that included six serotypes: Typhimurium, Montevideo, Anatum, Javiana, Braenderup, and Newport (104 to 106 CFU/g). Fecal samples were stored at ambient temperature. Populations were enumerated for up to 1 year (364 days) by spread plating onto tryptic soy agar supplemented with rifampin. When no colonies were detected, samples were enriched. Colonies were banked on various sampling days based on availability of serotyping in each state. During the 364-day storage period, Salmonella populations decreased to ≤2.0 log CFU/g by day 84 in pig, waterfowl, and raccoon feces from all states. Salmonella populations in cattle and deer feces were 3.3 to 6.1 log CFU/g on day 336 or 364; however, in Ohio Salmonella was not detected after 120 days. Salmonella serotypes Anatum, Braenderup, and Javiana were the predominant serotypes throughout the storage period in all animal feces and states. Determination of appropriate risk mitigation strategies following animal intrusions can improve our understanding of pathogen survival in animal feces.

Food Poisoning Bulletin

Homestead Creamery unsalted butter is being recalled because it may be contaminated with Listeria monocytogenes bacteria, according to a press release issued by the Virginia Department of Agriculture and Consumer Services. No illnesses have been reported to date in connection with this problem. The creamery is located in Wirtz, Virginia.

The Homestead Creamery unsalted  butter was distributed to the company’s distribution partners, through home delivery, and was sold in the company’s retail store. The recalled unsalted butter was packaged in 1/2 pound packages, marked with an expiration date of 04/30 printed on a sticker that was attached to the plastic packaging.

The potential for contamination was found after routine testing by Homestead Creamery found the pathogenic bacteria in the unsalted butter. Production of this product has been suspended while public health officials investigate the source of the contamination.

If you purchased this butter, do not eat it. There is zero tolerance for Listeria monocytogenes contamination in ready-to-eat products. You can discard the butter in a secure garbage can, or take it back to the place of purchase for a full refund.

Research – Why health experts aren’t warning about Coronavirus in food

Wbay

Chicken with Salmonella can make you sick. So can romaine lettuce with E. coli and buffets with lurking Norovirus. So why aren’t health officials warning people about eating food contaminated with the new Coronavirus?

The answer has to do with the varying paths organisms take to make people sick.

Respiratory viruses like the new Coronavirus generally attach to cells in places like the lungs. Germs like Norovirus and Salmonella can survive the acid in stomachs, then multiply after attaching to cells inside people’s guts.

“Specializing in what tissues to attach to is typically part of the disease’s strategy to cause illness,” according to the U.S. Centers for Disease Control and Prevention.

The CDC and other experts note that the virus is new and still being studied. But they say there’s no evidence yet that COVID-19 sickens people through their digestive systems, though the virus has been detected in the faeces of infected people.

How these germs spread also differs.

Respiratory viruses like the flu and the new Coronavirus spread mainly through person-to-person contact and air droplets from coughing, sneezing or other flying saliva.

What you should do

If you think you became sick from consuming a recalled product, call your doctor.

Check to see if you have the recalled products in your home. Recalled products should be thrown out or returned to the store where they were purchased.

Food contaminated with Listeria monocytogenes may not look or smell spoiled but can still make you sick. Symptoms can include vomiting, nausea, persistent fever, muscle aches, severe headache and neck stiffness. Pregnant women, the elderly and people with weakened immune systems are particularly at risk. Although infected pregnant women may experience only mild, flu-like symptoms, the infection can lead to premature delivery, infection of the newborn or even stillbirth. In severe cases of illness, people may die.

Background

This recall was triggered by the company. The Canadian Food Inspection Agency (CFIA) is conducting a food safety investigation, which may lead to the recall of other products. If other high-risk products are recalled, the CFIA will notify the public through updated Food Recall Warnings.

The CFIA is verifying that industry is removing the recalled products from the marketplace.

Illnesses

There have been no reported illnesses associated with the consumption of these products.

USA – U.S. lacks sufficient aflatoxin checks on peanuts destined for Europe

Food Safety News

The United States has limited controls to manage aflatoxin contamination in peanuts for export to Europe, according to findings from an audit carried out because of regular detection of non-compliances.

Officials from DG Sante, the European Commission’s unit for food safety and health, said there was scope to develop and improve good practices across the industry to help reduce levels of aflatoxin in peanuts.

The audit assessed if the systems to control aflatoxin contamination in peanuts sent to the European Union comply with, or are equivalent to, EU laws to ensure limits for contaminants are respected. It found the legal framework primarily addresses peanuts for the domestic market and imports. There are no specific standards for peanuts intended for the EU.

It is possible for processors to export a lot to Europe which has, in the analysis of another sample from the same lot, had a result exceeding EU limits, according to DG Sante.
