Research – Effects of edible coating containing Williopsis saturnus var. saturnus on fungal growth and aflatoxin production by Aspergillus flavus in peanuts

Wiley Online

Abstract

Production of aflatoxin by Aspergillus flavus in peanuts is both a health hazard and major problem. This study investigated the ability of a whey protein concentrate (WPC)‐based edible coating containing Williopsis saturnus var. saturnus to prevent growth of Aflavus and aflatoxin production in peanuts. WPC with/without Wsaturnus (7 log colony‐forming unit [CFU]/g) or Wsaturnus alone was sprayed on peanuts inoculated with Aflavus (3 log CFU/g) and stored for 84 days at 25°C. Application of coating with Wsaturnus reduced both growth of Aflavus and aflatoxin level by 82 and 69.5% compared with the control, respectively. Thiobarbituric acid values were around 60% lower in peanuts coated with WPC compared with the control. Sensory and chemical properties of peanuts were not significantly affected by coating treatment (p < .05). Based on results, coating with Wsaturnus appears useful in preventing both growth of Aflavus and aflatoxin production in peanuts.

Practical Applications

Improved WPC based coating containing W. saturnus can be applied on surface of roasted peanuts to prevent growth of A. flavus and aflatoxin production.

Research – Aflatoxin cross‐contamination during mixing of shelled almonds

Wiley Online

Abstract

Reports indicate that aflatoxin contamination in almonds comprise a few highly contaminated kernels among a much larger bulk with low concentrations, hypothetically due to cross‐contamination during processing. To test this, kernels exhibiting this distribution were generated by distributing 141.5 µg of aflatoxin between 20 almonds (approximately 7 µg each) which were then mixed with 5 kg (approximately 4,000 kernels) of local raw unroasted almonds for 20 min using an industrial mixer. A second 5 kg lot of noncontaminated kernels was marked for later identification then similarly mixed with the contaminated group. The groups were re‐separated and aflatoxin content was measured using High Performance Liquid Chromatography (HPLC) analysis. Twenty‐three micrograms of aflatoxin was recovered from the initially noncontaminated group, indicating cross‐contamination during mixing. Approximately 0.10 µg of aflatoxin was recovered from equipment surfaces. The results emphasize the need to reduce the potential for cross‐contamination between nuts by removing contaminated nuts and routinely cleaning processing equipment.

Practical applications

Shelled almonds have an atypical aflatoxin distribution that appears consistent with a combination of two distributions: first, infrequent highly contaminated nuts and second, a uniform low‐level aflatoxin contamination. This second distribution appears to come from cross‐contamination during postharvest processing, but this has not been previously tested. Results of this study confirmed that aflatoxin can transfer between contaminated nuts and uncontaminated nuts via simple mechanical mixing contact, as would occur during postharvest processing. Almond producers will want to take this finding into account when reviewing their processing and cleaning procedures and reduce any opportunity for nut to nut cross‐contamination by removing contaminated nuts as early as possible and routinely cleaning processing equipment.

Research – Prevalence and identification of Aspergillus and Penicillium species isolated from peanut kernels in central Myanmar

Wiley Online

Abstract

The objective of the present study was to conduct a survey to evaluate the postharvest handling of peanuts at farm level and to screen and identify the strains of Aspergillus and Penicillium species from peanut kernels in central Myanmar. A total of 640 samples from the stores of farmers, collectors, and wholesalers were collected and seeded for growth, isolation, and characterization of fungi. Out of 85 isolates, Aspergillus flavus (38), A. niger (20), A. terreus (15), and Penicillium citrinum (12) were identified and confirmed by molecular techniques including DNA sequencing using internal transcribed spacer (ITS5/4) and beta‐tubulin (Bt2a/2b) primer sets. The study indicates different factors associated with fungal contamination at farm level peanut storage and warrants an immediate attention of food safety regulatory authorities to design and implement strategies for postharvest handling and storage practice in developing countries to minimize fungal contamination.

Practical applications

In developing countries like Myanmar, there are lack of food safety practices and policies regarding the food storage, handling, and farmer education. The current study indicates the different storage methods for peanut kernels at farm level and their influence on prevalence of fungi. The study will give a deep insight to the policy makers to design food safety practices at farm level and educate the farmers to adopt the better practices to assure the consumer health and satisfaction in developing countries.

Hong Kong – CFS announces food safety report for October

CFS

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department today (November 29) released the findings of its food safety report for the last month. The results of about 16,400 food samples tested were satisfactory except for 21 samples and they were announced earlier. The overall satisfactory rate was 99.9 per cent.

A CFS spokesman said about 1,800 food samples were collected for microbiological tests, some 5,500 samples were taken for chemical tests and the remaining 9,100 (including about 8,400 taken from food imported from Japan) were collected to test radiation levels.

The microbiological tests covered pathogens and hygiene indicators, while the chemical tests included pesticides, preservatives, metallic contaminants, colouring matters, veterinary drug residues and others.

The samples comprised about 4,200 samples of vegetables and fruit and their products; 1,100 samples of cereals, grains and their products; 1,300 samples of meat and poultry and their products; 1,200 samples of milk, milk products and frozen confections; 2,000 samples of aquatic and related products; and 6,600 samples of other food commodities (including beverages, bakery products and snacks).

The 21 unsatisfactory samples comprised eight frozen confection samples detected with counts of hygiene indicator organisms exceeding the legal limits; three crab samples, one vegetable sample and one rice sample detected with excessive cadmium; two silver cod samples detected with mercury exceeding the legal limit; a fresh beef sample found to contain sulphur dioxide; a pickled green mustard sample detected with excessive preservative; a roast drumstick sample found to contain excessive Bacillus cereus; a vegetable sample detected with excessive pesticide residue; a nutmeg powder sample contaminated with aflatoxins; and a chilled chicken sample found to contain veterinary drug residue.

The CFS has taken follow-up action on the unsatisfactory samples, including informing the vendors concerned of the test results, instructing them to stop selling the affected food items and tracing the sources of the food items in question.

Since the Pesticide Residues in Food Regulation (Cap 132CM) came into effect on August 1, 2014, as of October 31 this year, the CFS has taken over 189,500 food samples at import, wholesale and retail levels for testing for pesticide residues. The overall unsatisfactory rate is less than 0.2 per cent.

The spokesman added that excessive pesticide residues in food may arise from the trade not observing Good Agricultural Practice, e.g. using excessive pesticides and/or not allowing sufficient time for pesticides to decompose before harvesting. The maximum residue limit (MRL) of pesticide residues in food is not a safety indicator. It is the maximum concentration of pesticide residues to be permitted in a food commodity under Good Agricultural Practice when applying pesticides. In this connection, consumption of food with pesticide residues higher than the MRL will not necessarily lead to any adverse health effects.

The spokesman reminded the food trade to ensure that food for sale is fit for human consumption and meets legal requirements. Consumers should patronise reliable shops when buying food and maintain a balanced diet to minimise food risks.
